Get a usable photo first.
The capture screen is built on CameraX with a hand outline over the preview. A bad photo spoils every step after it, so the flow starts by getting the hand where the outline is.

Palm reading
starts with the camera.
An AI palmistry app: the user photographs a palm, answers a couple of questions and gets a reading broken down by palm line. Published on Google Play.

A guided photo,
then a reading.
Future Lines takes the user through a short onboarding, a camera screen with a hand outline, a quick quiz and a subscription offer. The main screen splits the reading into palm lines, each with its own explanation.
I developed the Android app, including the camera flow and two distribution builds with separate billing.
The screens below are from the current Google Play build, captured on a Pixel 9 Pro XL.

The first screen, the palm line overview and a line explanation. Open any capture to inspect it.
03 / ENGINEERING CONTRIBUTIONSCamera, checks,
Camera, checks,
and two channels.
The app is small, so the work went into the parts that decide whether a reading is possible and how it is paid for.
Tell the user what is wrong.
ML Kit pose detection runs on the device and checks whether the hand is inside the guide frame. When it is not, the user sees a hint instead of waiting for a poor result.

One codebase, two channels.
Google Play and direct-APK builds come from the same code as two product flavors, each with its own billing path.
Gradle product flavors · Google Play Billing
Show value before the paywall.
The subscription offer comes after the photo and the quiz, and each line explanation is partly free, so users see what they would pay for.

Camera, on-device ML
and distribution.
Future Lines covers a guided camera flow with an on-device check, product flavors for two distribution channels, and subscription monetization in a consumer app.
