Flexify is an open-source gym tracking application engineered to record strength and cardio workouts without internet connectivity. Licensed under the MIT license, it enables athletes to log reps, track weights, configure rest timers, and analyze physical progression locally on their devices.
Technical Overview of Flexify
Built with the Flutter framework, Flexify operates completely without network permissions, eliminating background data transfer overhead and remote telemetry. The software is distributed as portable archives for desktop environments that execute without traditional installation, as well as native application packages for mobile devices. Data storage relies on a local relational SQLite database with integrated schema migration tools to maintain fast read and write speeds directly on internal storage.
Core Features of Flexify
- Offline-only architecture ensures complete data sovereignty by operating with zero internet access, network permissions, or third-party analytics.
- Comprehensive exercise logging handles both resistance metrics like weight and repetitions alongside diverse cardio training entries.
- Visual progress graphs plot strength curves and training history across custom timeframes directly inside the local interface.
- Built-in rest timers trigger audible alarms between training sets to keep rest intervals structured and consistent.
- Modular interface controls let users toggle specific workout tools on or off and switch between dark and light themes.
System Compatibility & Updates
Flexify provides official builds for Android (ARM64, ARMv7, x86_64), Windows (x64), and Linux (x64). Recent version updates delivered stability fixes for the workout chart renderers by properly clipping border edges, corrected field spacing across cardio entry pages, and improved test automation workflows.
Why Choose Flexify?
Flexify delivers complete training privacy by keeping your entire lifting log stored strictly on local hardware without subscriptions or mandatory account creation. Its clean, MIT-licensed design combines rest alarms and performance charts into a lightweight, distraction-free tracker that respects your hardware.
