Two separate codebases
Building iOS and Android separately doubles the work. We use React Native and Expo for one shared codebase.
We build a mobile MVP for iOS and Android from one codebase and submit it to the App Store and Google Play within 2 weeks. Store approval is outside our control, so we never promise it inside those 2 weeks. With DiaryDad, both stores approved the app on the first attempt and it was live 14 days after kickoff; our experience with store submissions helps, but each review depends on Apple and Google.

Mobile apps carry work a web MVP does not: two platforms, device testing, and store review. Planning for these on Day 1 keeps the build on track.
Building iOS and Android separately doubles the work. We use React Native and Expo for one shared codebase.
Missing requirements such as account deletion or privacy details can lead to rejection. We check these before submission.
Mobile screens need fewer steps. We design the journey for the phone from the start.
One app for iOS and Android, ready for store submission.
Technologies we use for this
App Store and Google Play review is outside our control, so we never promise store approval within the 2 weeks. We build and submit inside the sprint; approval timing depends on Apple and Google.
Day 1
Your one to three decision makers sit with our product manager or lead developer. We decide which part of the product will test your idea and write down what waits for later.
Days 2–3
We study your top two or three competitors, agree the pages and screens, finalise the user journey, and use AI to create a demo from your brand guidelines.
Days 4–9
Our developer builds the core features, sign-in, database, and the other parts the product needs, using AI coding tools such as Claude, Cursor, and Codex.
Day 10
We create the production builds and submit them to the App Store and Google Play.
Days 11–14
We test on real devices through TestFlight and internal testing, make one or two rounds of changes, and respond to store review.

Built an iOS and Android AI journaling app with React Native and Expo from the client's designs. Both stores approved it on the first attempt, and it was live 14 days after kickoff.
App Stores Deployed
Kickoff to Live on Both Stores
Attempt Approval: App Store & Google Play
App Store and Google Play review is outside our control, so we never promise store approval within the 2 weeks. We build and submit inside the sprint; approval timing depends on Apple and Google.
Yes. The listings belong to you, so you keep the app, its reviews, and its ratings. We help you set the accounts up.
On a fixed-price project, fixing a rejection and resubmitting is our responsibility. On an hourly project, we plan for one rejection in the estimate; unexpected extra rounds are billed as extra hours.
Yes. Building for more than one platform, such as a mobile app plus a website, adds to the price.
