TrainUs is a training-tracking application. You create exercises, group them into combos (crossfit-style sequences, timed or not), then into sessions. Sessions can in turn be organized into collections — a multi-week program, for example. When it’s time to train, you launch a session in Execution Mode: the app guides you step by step, with a timer for timed combos, and keeps a record of everything you actually did (reps, weight, duration) so you can track your progress in the statistics.https://kaivalya.eu/projects/trainUs/en/docs/how-to-guides/Tue, 16 Jun 2026 00:00:00 +0000https://kaivalya.eu/projects/trainUs/en/docs/how-to-guides/Install TrainUs as an App on Android TrainUs is a Progressive Web App (PWA): it installs as a real app on your phone, with its own home screen icon, and runs without the browser’s navigation bar. Important: if TrainUs is already open in a browser tab, the installed app may not launch correctly — the browser and the installed app conflict with each other. Close the browser tab first before launching the installed app.https://kaivalya.eu/projects/trainUs/en/docs/user-guide/Tue, 16 Jun 2026 00:00:00 +0000https://kaivalya.eu/projects/trainUs/en/docs/user-guide/This page describes every TrainUs screen in detail: available actions, form fields, keyboard shortcuts. For a general introduction, see Getting Started; for the “why” behind the choices, see Understanding TrainUs. First Launch The very first time you open TrainUs, a one-time warning modal explains two important constraints of the app: One tab at a time — TrainUs can only be open in a single browser tab at once. Opening it in a second tab causes errors.https://kaivalya.eu/projects/trainUs/en/docs/understanding-trainus/Tue, 16 Jun 2026 00:00:00 +0000https://kaivalya.eu/projects/trainUs/en/docs/understanding-trainus/Why a Local App? Many fitness apps run on an account and a central server: convenient for syncing your devices, but it also means a third-party company hosts your data, and the app becomes unusable without a connection — or if the service shuts down one day. TrainUs makes the opposite choice: everything runs in your browser, your data is stored locally, and nothing is ever sent to a server. This choice has a cost — no automatic sync or backup between devices — but that cost is covered by simple, manual solutions: see the How-to Guides for backup and sync.
