Pet projects

My Simple Workout Tracker

- a personal workout tracker. (In development) Web-application oriented on usage on smartphones. Developed with React, Capacitor, IndexedDB, NodeJS(Express), MongoDB. The app for my own purposes since I didn't find any suitable one on Play Store. You can create exercises, compose workouts, track progress. Development in progress but most of functionality is already implemented. At the moment I'm migrating the project to Capacitor with adding plugins on Java and SwiftUI and planning to release it on RuStore, Play Store and App Store.
