Tempo is a fast interval timer that turns plain-English workout descriptions into structured intervals you can run.
Describe what you want — "8 rounds of 30 seconds work and 15 seconds rest", "tabata", "20 minutes mixed boxing", or paste a list of strength sets — and Tempo converts it into a timed workout with audio cues, haptic feedback, and a clean ring display.
If you'd rather skip the prompt, jump into a preset: Tabata, Quick HIIT, Sprint Intervals, or Long Endurance.

PRIVACY
Tempo is built to stay out of your way. No account is required. Analytics are anonymous (no user identifier). Crash reports contain stack traces only — never your prompts or
workout content. When you dictate a workout, the audio is sent to OpenAI for transcription and discarded; the text prompt itself is sent to OpenAI to generate the workout
structure and is not stored on Tempo's servers afterward.

SUBSCRIPTION / PRICING
Tempo is free to download and use. The timer, presets, your own workouts, workout history, voices and themes are free for everyone, along with 5 AI-generated workouts every month
and the current month in the calendar.
Tempo Pro is an optional auto-renewing subscription, available monthly or yearly (the yearly plan starts with a 7-day free trial). Pro adds up to 100 AI-generated workouts a
month (instead of 5), your full calendar history, every saved workout, and workout planning with reminders and a weekly template. Prices are shown in the app before you buy and may vary by country.
Payment is charged to your account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current
period; you can manage or cancel it in your account settings at any time. Any unused part of a free trial is forfeited when you buy a subscription.
