# About Calypstok Calypstok is a workout companion for people who train with gym equipment. The app combines structured training plans with the real machines available to the user. A user can choose a sport/activity training plan, select the training day (A, B or C), complete exercises, and record the actual weight used. Calypstok remembers the user's machine-specific weights and provides Progress views so the user can see whether the weight used on a machine is changing over time. The app also provides exercise alternatives where available, a training calendar, optional Measurements, and a Gym Bag checklist. Several people can share one device — each keeps their own plan, history, and machine weights. Calypstok is available in Polish and English. Calypstok does not provide medical or therapeutic advice.
