Lots of people have a good app idea. Far fewer get it into the App Store and Google Play, and fewer still get people using it. The difference is rarely the idea. It's usually the process.
Here's the path from "I've got an idea" to "it's live", step by step.
1. Check people actually want it
Before spending a rupee on development, talk to the people you're building for. Ask how they solve the problem today and what annoys them about it. If you can, put up a simple landing page describing the app and see whether anyone signs up for early access. Ten honest conversations will teach you more than any amount of planning on your own.
2. Define your MVP
Your minimum viable product is the smallest version that solves the main problem well. List every feature you want, then cut ruthlessly. A good test for each feature: would a user stop using the app without it? If not, it can wait for version two.
3. Sketch the screens
Map out every screen and how users move between them. Start rough with pen and paper, then turn it into wireframes and finally a clickable prototype. Showing a prototype to a few real users at this stage can save you weeks of rebuilding later.
4. Choose how to build it
Decide on native or cross-platform (we compare them in this guide), what backend you'll need, and which ready-made services you'll use for logins, payments and notifications.
5. Build in short cycles
Good teams build in one or two week cycles and show you working progress at the end of each one. That way you can try things on your own phone and change direction early, when it's cheap, rather than at the end, when it isn't.
6. Test properly
Test on a range of real devices, including cheaper Android phones with less memory, since that's what many Indian users carry. Check slow mobile connections, what happens when the internet drops halfway through a payment, and every error message.
Then get real people using it. Apple's TestFlight and Google Play's testing tracks let you share pre-release versions.
Plan for this: at the time of writing, Google Play requires new personal developer accounts to run a closed test with at least 12 testers for 14 days in a row before the app can go live publicly. Organisation accounts aren't subject to this rule, which is one reason to register as a business.
7. Prepare your store listings
Both stores need more than just the app. Get these ready in advance:
- App name, short and long descriptions, and keywords
- Screenshots for different screen sizes, and an app icon
- A privacy policy hosted on your website
- Apple's App Privacy details and Google Play's Data safety form, explaining what data you collect and why
- If users can create accounts, a way for them to delete their account from within the app. Both stores require this.
- Login details for reviewers, if your app needs an account
8. Submit for review
Apple reviews every app, and rejections on a first submission are common. The usual reasons are crashes, broken links, missing privacy information or features that don't work for the reviewer. Don't panic if it happens. Read the feedback, fix it and resubmit. Leave a few days of buffer before any launch date you announce publicly.
9. Launch and tell people
Nobody stumbles across a new app by accident. Tell your existing customers, share it on social media, put download links on your website and ask early users for reviews. Store ratings have a big effect on how many people install.
10. Measure, listen and improve
Track what people actually do: where they drop off, which features they use, and what they complain about. Your second version should be shaped by real behaviour, not assumptions.
