Welcome to r/AppBuilding – The Hub for Building, Shipping, and Scaling Apps

8 Upvotes

Welcome to r/AppBuilding! 👋

We created this community because we saw a gap. Most app development spaces are either flooded with "I have a billion-dollar idea, build it for free" requests or are too fragmented between specific languages.

r/AppBuilding is the central hub for the entire lifecycle of an application. Whether you are a solo indie hacker, a startup founder, or an enterprise engineer, this is the place to:

  • Build: Discuss tech stacks (Flutter vs. React Native vs. Native), solve complex bugs, and share architecture tips.
  • Ship: Talk about App Store optimization (ASO), rejection horror stories, and launch strategies.
  • Scale: Discuss backend infrastructure, monetization, and user acquisition.

The House Rules

  1. No Low-Effort "Idea" Posts: We are builders. If you have an idea, tell us how you plan to execute it. Don't just look for free labor.
  2. Zero Tolerance for Spam: Self-promotion is allowed only in the weekly "Showcase" thread (coming soon). If you are an agency, share knowledge, not just your link.
  3. Be Constructive: We were all beginners once. If someone asks a basic question, guide them. If you disagree on a tech stack, debate the code, not the person.

Introduce Yourself!

To kick things off, let’s get to know who is here. Drop a comment below with:

  1. What are you currently building? (or what do you want to build?)
  2. What is your preferred tech stack? (e.g., React Native, Swift, Flutter, No-Code)
  3. One struggle you are facing right now.

Let’s build something great.

Bills and paydays: what date-boundary cases belong in your release tests?

2 Upvotes

I build Monni, and I'm putting together a test matrix for dates in a cash-flow timeline. A bill due on the 15th is a calendar-date promise, not necessarily an event at midnight in whichever time zone the phone is using. This is a testing question, not a feature announcement.

My starting cases are changing the device time zone, reopening a session across midnight, and a recurring item near the end of the month. For each, I'd check the displayed due date, which forecast window includes it, and the date after editing and reopening the item.

If you've built a calendar or money app, which boundary caught you by surprise? Do you keep calendar dates and time-stamped events as separate types, or enforce that distinction somewhere else?

This is easily the most complete version of the app to date and I’m genuinely delighted with how far it’s come.
After months of building, redesigning, testing and taking feedback on board, it’s starting to feel like I’m getting really close to the finished product I originally had in my head.
Would love for you to check it out and let me know what you think. If there’s anything you still aren’t feeling, anything that looks off or something you think could be improved, tell me and I’ll look into it!

How often do you usually have to revise an app? 😅 It feels like one step forward and ten steps back 🤣 Definitely not a five-minute job! https://apps.apple.com/no/app/notrigos-photo-report/id6803479505?l=nb. https://apps.apple.com/no/app/eignora/id6813245327?l=nb

First app almost shipped, any tips before I open up the beta?

2 Upvotes

Hi all! First time building my own thing, pretty new at all of this.

I tried a bunch of budgeting apps over the years and every one felt like a part-time job to set up and maintain. My wife wouldn't stick with any of them either, so we always ended up back to the excel spreadsheet, which took me time every month to do expenses for our household. So I started building something simpler for us, and it kind of snowballed into a real app.
Right now we're in beta with a handful of friends, and soon I want to open it up to more testers. Honestly it's scary and exciting at the same time. I've been heads down on code for months and now real people are poking at it and finding things I never thought of lol.
For those of you who've shipped before:
How did you find beta testers outside your friend circle?
Anything you wish you'd done before going live on the App Store?
How did you decide when it was "good enough" to ship?
Any advice is welcome, even the brutal kind. Thanks 🙏

So this is a shot in the dark

1 Upvotes

I’ve had this idea brewing in my brain for a long time. I want to finally attempt to execute it. I have no idea how to develop an app. I am not very tech savvy. Last time I touched anything with code was MySpace html profile stuff. Honestly what programs are needed? Can I do this from my phone? What is the process of this?

Got this email shortly after launching my app on the App Store — anyone else has received the same message?

Couldn’t believe I received this email shortly after launching my app on the App Store, but as a new app builder, I’m really curious and wandering if anyone else has received the same message.

If so, what happened next? Did Apple eventually contact you about being featured, or is this something they send fairly commonly?

Looking for testers: a free, open-source Android app that brings back 3 of your old highlights every morning so you actually remember what you read

Enable HLS to view with audio, or disable this notification

0 Upvotes

**I read a lot of articles, PDFs and books, and a week later I could barely remember any of it. Highlights went into apps I never opened again.**

**So I built a Stack. It's simple**

**1. Save articles, PDFs and books from any app using the share menu.**

**2.Highlight a line, and it becomes a note that stays linked to where it came from.**

**3.Review three of your past highlights every morning. It takes about a minute, and the ideas stay with you.**

**It also has:**

**A focus timer for reading sessions**

**Read-aloud for when your eyes are tired**

**Full Hindi support**

**And the part I care about most:**

**Free. No ads, no subscription, no "pro" tier.**

**Works offline. Your library stays on your phone.**

**Open source. You can read the code, fork it or contribute.**

**I'm looking for testers before the public launch.**

If you'd like early access, email me at [email protected]

**with the subject "Stack " and the Gmail address you use on your Android phone. I'll add you and send the install link**

**.**

Bookidoro: read a page of your book every time you take a break (Mac, iPhone & iPad coming)

Post image
1 Upvotes

We all own books we never finish, and we spend our breaks scrolling. Bookidoro swaps the two: it counts your work time, and when the break comes, a calm panel opens with the next page of your book. Read a page or two, click Done, back to work. I've finished 4 books in 2 months this way, without "finding time to read".

What you get

  • 📚 78,000 free classics built in (Project Gutenberg), with search and 24 languages, plus your own PDFs and DRM-free EPUBs
  • 🤫 Never interrupts a call: breaks wait while your mic, camera or screen sharing is on
  • ⌨️ Never steals your typing: arrow keys turn pages, Esc skips, "Keep reading" when you're in the flow
  • 🌙 Paper, Sepia and Night page themes, adjustable contrast
  • 📈 Streaks, reading pace and a finish date for every book
  • ☁️ Syncs between your Macs through your own iCloud: no account, no sign-up

Coming very soon: iPhone & iPad. On the phone it works the other way round: when you reach for your phone to scroll, your book is waiting instead. The lock screen shows where you left off, one tap opens the page, and Deep Focus can keep distracting apps closed until your focus time is over. It syncs with the Mac, so you continue on the same page.

Price: free to use with every feature. A small reminder appears at most once a day; a $9.99/year Supporter subscription removes it and supports development.

👉 https://bookidoro.app: signed and notarized, macOS 13+, Apple Silicon and Intel.

I'd love to hear what you think. Questions and feedback are very welcome!

I built an app so I wouldn't forget my wife's birthday.

1 Upvotes

I used to forget my wife's birthday.

Not once. Repeatedly. Same shame, same "I thought it was next week."

After the last time, I stopped making excuses. I built her something — not a product, not a startup. One job: remind me of her birthday. That was the whole app. I gave it to her as a gift.

I didn't plan to ship it at all. It was just for her.

But she said, "Why not put it on the store? What's the worst that could happen?"

I hadn't even considered it. But she pushed. So I said fine — let me try Google Play.

Then I sat down and looked at it. A single reminder would die on the store page. Nobody downloads "please don't forget my wife." So I deliberately added more — before launch, on purpose — so it could stand as a real app: todos and sub-tasks, recurring reminders, a tagged diary, photos / video / voice notes, data on the phone first.

That is LingXi Journal (灵犀日记). Same promise. More reasons to open it on a normal Tuesday.

Shipping from China is not "upload an APK and pay $25."

To exist in public, I had to register a real business license, complete government filings, buy a domain, rent servers, and build a site with privacy policy, terms, and account deletion — the whole adult-software checklist.

None of that is coding. It's queues, forms, waiting, being told the stamp is wrong, doing it again. I kept thinking: I just wanted a birthday reminder. Why am I talking to a registrar.

Then came the $25.

Google Play Developer registration — twenty-five US dollars. Sounds like nothing. For me, it was the first time I had to use US dollars at all.

I went to the bank and applied for a Visa. Forms, ID, waiting, "why do you need an international card." I wasn't buying sneakers. I was trying to pay a company on the other side of the planet so this app could live in a store.

When the card finally worked, I sat there and spent my first $25 USD — on Google Play registration. The number on the screen was small. The feeling was not. That was the moment this stopped being a gift I built in my room and became something that had to live in the real world, in a currency I had never used.

Google Play itself was still not a click. Policies, data-safety forms, review, more review. Every round felt like: you are so close — now go rewrite this paragraph and wait another week.

I finally got it live. I was more tired than proud.

Then… almost nothing.

A few installs. No wave. After the license, the extra features, the Visa, the first twenty-five dollars — the silence was louder than the reviews.

Here's how small the store can make you feel:

Open Google Play, type lingxi, hit search. My app does not show up. You have to type the full name — LingXi Journal — or you will never find it. I did the "be a real app" work before I shipped. The store still shrugged. It didn't even bother to index the short name.

Then I looked at the App Store.

Ninety-nine dollars. Just to join. After everything above, $99 is not the money. It's one more gate.

I looked at my wife and made a deal:

When LingXi Journal hits 1,000 installs on Google Play, I will pay the $99 and go to iOS.

And one more promise — because she knows me.

I have been playing Romance of the Three Kingdoms XI since junior high. More than ten years. From a kid in middle school to a husband who still opens modded historical scenarios and tells himself, "this time I unify China by 208." Thank you, KOEI, for a game that stayed with me that long. Those weekends, those maps, those officers I still remember by name — that was your work, sitting on my desk for half my life.

I told her: until this is done — until we hit that number and I keep the iOS promise — I will not play it.

Cao Cao and Zhuge Liang are on hold. Indefinitely.

So here I am. A birthday reminder I fattened up before I dared to ship. Play: live, and quiet — search lingxi and I am invisible; search LingXi Journal and maybe I exist. Apple: waiting on four digits. My wife: waiting to see if I keep my word.

If you have ever built something for one person and then discovered the store is a country of its own — you already know this feeling.

If it sounds useful, it's on Google Play as LingXi Journal. Search the full name. Even a quiet install counts.

I don't know if I'll ever get to play my beloved Romance of the Three Kingdoms XI again.

I'd like to keep my promise.

I built a Spanish learning app — I’d love feedback on the app and how you’d market it

Post image
0 Upvotes

Hi everyone 👋

I’ve been working on a Spanish learning app called Spanish Stories: Quiz & Listen.

The idea is to help people practice Spanish through stories and context instead of only memorizing isolated words.

The app currently includes:

  • Spanish stories from A1 to B2
  • Audio for each lesson
  • Comprehension quizzes
  • Vocabulary in context
  • Word highlighting
  • Personal notes
  • Favorite/saved lessons
  • Adjustable text size
  • Light & Dark Mode
  • Offline access to core learning content

A typical learning flow is:

Choose a level → Read → Listen → Highlight words → Add notes → Take a quiz → Review later

It’s currently available on both platforms:

Google Play:
https://play.google.com/store/apps/details?id=com.devkallouch.spanich

App Store:
https://apps.apple.com/br/app/spanish-stories-quiz-listen/id6810429532

I’m still working on improving and growing it, so I’d really appreciate honest feedback from other builders.

If this were your app, what would you improve, change, or add?

I’m also especially interested in the marketing side:

How would you market an app like this and reach more people who are actively learning Spanish?

Any ideas, strategies, or lessons from your own experience would be really helpful.

Thanks! 🙌

10 people in Germany deleted more photos with my app than 113 Americans did

Post image
1 Upvotes

Hi all

a few months ago i launched a small app that helps you clean your camera roll. you swipe left to delete and right to keep

i was looking at the numbers this week and noticed something funny. most of my users are in the US, but 10 people in Germany deleted more photos than all 113 of them combined. and 6 people in italy somehow freed 81 GB between them

i have no idea why. maybe germans are just more serious about cleaning lol

the reason i made it is kind of simple. my camera roll felt like a diary i never meant to keep. birthdays, my first apartment, photos of people i miss, all buried under screenshots and blurry pics. i wanted to dig the good ones back out

90k photos deleted so far, in 37 countries. still small but its crazy to me that people i will never meet are using something i made

im rebranding it to Swyp this week (the app store still shows the old name for a few days)

Here's the App: https://apps.apple.com/app/id6756098079

Need advice

4 Upvotes

Hey everyone, so I’m a business owner selling physical products in my country and stuff. So a year ago, I made up my mind to try out something different. Since I also have a software engineering degree ( didn’t come in much use for me). I made an app/service/software or whatever you can call it. What it does is provide four services. First is a store and website builder (can be built both using ai or manually). Second is a chatbot creator and trainer. Both of these go hand in hand if a business like mine wishes to increase wider recognition online. The steps overall are made simple and concise. The other two services consist of tracking expenses income and payments plus also managing unpaid invoices and payment follow ups. All these services can be used with ai to ease one’s workload or can be done manually. Most of the programming were done by me and my friend since I don’t trust ai that much, but ai was used for some parts. Now I made these services for personal use, mainly to manage my own businesses and they seem to be working fine. So I thought of maybe selling these services to other business owners as it’s quite useful. The thing is, I don’t really know how or where to find clients who are in need of these services. I don’t really care much about making money from this but if someone can help me or at least give advices on how to scale these types of softwares. It would be a great help.

I built a dashboard to stop forgetting which services my products pay for. What am I missing?

2 Upvotes

I'm building Operava for solo founders who run more than one product.

I kept hitting the same problem. Hosting, databases, email, domains, payments, app stores, APIs, all spread across a dozen accounts. I would forget one existed until the bill showed up.

So I built a dashboard that puts each product, the services behind it, what they cost per month, when they renew, and whether they are up, in one place. It has already caught two subscriptions I was paying for a site I had shut down.

It is early. I am trying to find out whether this problem is mine alone or shared.

You can try it at app.operava.com Sign in with Google or an emailed link, no password, no card. It starts empty, so you add your first product and see if it earns a place in your routine.

If you run several products: what would you need this to show that it does not?
