Kronos

Kronos is a workout app for your phone. Ask your AI for a workout, a multi-week plan or an interval timer and it opens in Kronos, ready to run, with timers, rest, set logging and the weights you lifted last time. You can also show it on a TV.

Before anything is saved, Kronos checks it against its exercise catalogue and shows a preview of exactly what will run. Nothing is saved until you agree.

With your permission it can read your plan, your saved workouts, your setup and your training history, so the next session fits what you actually did. It can change this week or next week of your plan, and only what you ask: swap a move, add a set, skip a session.

For coaches: write a plan with your AI and send it to a client who linked you, with the rules you want kept (moves they must do as written, the swaps you allow, a weekly load limit, a shortest session). Where a client chooses to share their training with your AI, it can read what they did against what you prescribed: sets, reps, loads, effort, swaps and skips, and whether each change was within your rules. A client can stop sharing at any time. Creators can also save drafts to their Kronos Studio.

Needs a Kronos account and the Kronos app. Workouts run in the app, not in the chat.
