TreeSheets is free Zlib-licensed desktop software. You supply the computer, storage and backups. Its optional local agent socket is off by default; connecting an external AI assistant has that provider’s own account, model and service terms and can cost separately. The application does not include a paid-model allowance or a managed team workspace.

The GPL-3.0 source and documented desktop packages have no required application subscription. Your computer, storage and backups are separate costs; no managed synchronization service or cloud quota is included.
Record habits and inspect progress on an Android phone.
Loop is free GPL-3.0-or-later Android software. The provider states there are no in-app purchases or artificial habit limits, and all features are available to every user. No account or hosted service is required. It replaces local habit schedules, reminders and progress charts, rather than Habitify’s cross-platform account sync, location reminders or paid integrations. Data stays local in the app; Android’s own backup settings can separately copy device data to Google. Keep your own exports before switching devices.

Key MapperProduct logo · See the interface on the official websiteCreate useful physical-key shortcuts on an Android device.
The reviewed GPL-3.0 FOSS edition has a usable free core for physical-key remapping and actions. The provider explicitly offers certain advanced triggers and special features as paid add-ons; do not label the entire product feature set free. F-Droid also flags promotion of the paid Play version. This selection covers the available FOSS package, not a paid extension or every Button Mapper Pro feature. Some actions need accessibility, keyboard, Shizuku, ADB or root support and can depend on Android version and device hardware; basic remapping does not require buying a server or API.
Fossify CalendarProduct logo · See the interface on the official websiteKeep events, recurring reminders and calendar widgets on your Android phone.
The GPLv3 Calendar source links official package routes including F-Droid and has no required source-license subscription. You provide the Android device and any configured calendar account/service; those services may charge separately. Fossify does not supply a hosted synchronization plan. Prices and features of separate supporter apps were not verified here.
