Introduction
As a security and app developer enthusiast, I’ve been using Flipper Zero for some time now. For those who don’t know, Flipper Zero is a versatile multitool device designed for hardware and RF enthusiasts, security researchers, and hobbyists. It’s a portable gadget that can interact with various digital systems and wireless protocols.
Flipper Zero has a range of capabilities, including reading and emulating RFID cards, interacting with NFC devices, transmitting and receiving radio signals, and communicating with infrared devices. It features a compact design with a monochrome display, navigation buttons, and an SD card slot for expandable storage. The device runs on open-source firmware, which is one of its most exciting aspects.
The cool thing about Flipper Zero is that you can write custom applications for it, which is exactly what I’ve been trying to do. Recently, Flipper allowed Rust language execution, and I jumped into the possibility of writing an application in Rust for Flipper. However, I faced some challenges. The unsafe clusters and the way Rust is built made it difficult for me to write the apps the way I wanted.
That’s why I decided to implement the same idea directly in C programming language, often referred to as the father of all languages. These endeavors ended up with the creation of Flipper Time Tracker.
Flipper Time Tracker is an application for the Flipper Zero device that allows the user to track multiple tasks simultaneously. The application uses a CSV file to store and handle task data, which can be easily exported to Excel or similar software for further analysis. This approach also allows for tracking task time in the background or even when the device is switched off!
Features
- track multiple tasks at the same
- start / stop the task at will, resume tracking when needed.
- mark task as complete
- edit task details (name, description, price per hour)
- quick continue last used task
- task running with timer counter view
- you can download your csv file from
apps_data/trackerflipx/data.csv
This project showcases the potential of Flipper Zero as a platform for custom application development. The active community of developers and users who create and share applications and modifications for Flipper Zero has been a great source of inspiration and support throughout this project. It’s exciting to see how this compact device can be transformed into a practical tool for time management and productivity.
