How to build a Pomodoro timer app for iOS
What a Pomodoro timer app needs
- A timer with configurable work and break intervals, for example 25 and 5 minutes
- A long break after a set number of sessions
- A session counter and a simple daily focus total
- Local notifications so an interval ending is announced even when the app is backgrounded
- A Live Activity on the Lock Screen and Dynamic Island showing the live countdown
- Sound and haptic cues at the end of each interval
- Optional history and stats so users can see focus time over the week
Background timing is the detail that separates a real Pomodoro app from a toy. Schedule notifications for interval ends rather than relying on a timer that the system may suspend.
How to build it with AppFlight
Describe it in plain English, for example: "A Pomodoro timer with 25-minute work and 5-minute break intervals, a longer break after four sessions, a count of completed Pomodoros, a notification and haptic when each interval ends, and a Live Activity on the Lock Screen showing the countdown. Let me adjust the interval lengths in settings." AppFlight plans the screens, generates native SwiftUI, wires up the notifications and the Live Activity, and launches it in a live simulator so you can run a cycle and watch the Lock Screen behavior. You iterate in plain language, for example adding ambient sounds or a weekly stats view.
Monetization for a Pomodoro timer app
The proven model is a free basic timer with a paid upgrade. Free users get standard intervals and the core timer; the subscription unlocks custom interval lengths, detailed focus stats and history, extra sounds, and themes. Add a RevenueCat paywall for subscriptions, and use Superwall if you want to test paywall designs without shipping an update. A few dollars a month, or a discounted yearly plan, fits this category.
Shipping it to the App Store
When the app is ready, AppFlight signs the build, uploads to TestFlight so you can confirm the notifications and Live Activity work on your own device, then submits to the App Store with metadata and screenshots from the simulator. If Apple rejects the build, AppFlight reads the reason, works on the fix, and resubmits. Apple reviews every app, so a submission is not the same as an approval, but the whole pipeline runs without you opening Xcode.
FAQ
Do I need to code to build a Pomodoro timer app?
No. You describe the app in plain English and AppFlight generates native Swift and SwiftUI. You can read and edit the generated code, but it is not required.
How does a Pomodoro app keep timing when it is in the background?
It schedules local notifications for the end of each interval, since a timer cannot run freely in the background. A Live Activity on the Lock Screen and Dynamic Island shows the countdown, and the notification fires when an interval ends.
How do focus timer apps make money?
A free basic timer with a subscription for custom intervals, detailed focus stats, sounds, and themes is the common model. A RevenueCat or Superwall paywall handles the subscription, usually a few dollars a month or a yearly plan.
