StreakApp is a small Codename One app for tracking daily language-study streaks from real Android app usage. It reads Android Usage Access statistics locally, checks whether the configured study apps reached their daily target, and keeps a simple streak with limited streak freezes.
- Tracks usage time for AnkiDroid, Duolingo, Drops, Rosetta Stone, Talkpal, and Quizlet.
- Lets each app be enabled or disabled and gives each app an editable daily minute target.
- Supports calendar days ending at midnight or study days ending at 4:00 AM.
- Awards one streak freeze every four completed days, capped at four available freezes.
- Opens the tracked Android apps directly from the dashboard.
- Refreshes usage asynchronously and refreshes again when the app returns to the foreground.
- Supports English and Italian localization. Additional localizations can be added fairly easily.
- Supports system, light, and dark appearance modes.
- Supports in-app text size adjustment on top of the device text settings.
StreakApp reports the time an Android app remains in the foreground, not the strict amount of active study time inside that app. Android's usage statistics include the time spent while the app is launching and visible. On an older phone, for example, a language app that takes twenty seconds to start can add those twenty seconds to the foreground total.
For this reason, the daily minute target for each app is editable. You can tune the target to account for launch time and other foreground time that is not actual study.

Usage tracking requires Android's Usage Access permission for StreakApp. The app does not request a normal runtime permission dialog because Android exposes this permission through system settings.
All usage calculations happen on the device. StreakApp does not send usage data to a server.
