Add HabitFlow (flipper_habit_flow) to Apps Catalog under Tools.

[Endika]

Application Submission

HabitFlow is an offline habit tracker for Flipper Zero. You define habits with a day-based goal (1–365 days, default 66), mark today as done from the device, and see streaks, your record streak, and progress toward mastery.

When the calendar advances, the app can walk through a short “did you finish yesterday?” flow so streaks update in a deliberate way; longer gaps without opening the app are handled according to the rules described in the README.

This submission: first listing of HabitFlow in the Apps Catalog (applications/Tools/flipper_habit_flow/manifest.yml), targeting source commit 6cfbe2100bb203233c15895cf52226aaf1ad6561 on https://github.com/Endika/flipper-habit-flow (version 0.1.2 per application.fam).

Extra Requirements

• Hardware: none beyond a stock Flipper Zero (no GPIO, Sub-GHz, NFC, etc.).
• Software: none beyond installing the .fap from the catalog; data is stored automatically in the device app data area (no PC or phone required for normal use).
