About Zestimer

Zestimer is an interval timer for iPhone and Apple Watch that calls every switch — work, rest, round — with voice and haptics, so you never watch the clock mid-workout. Paste a YouTube workout and it becomes a timed, follow-along session; or tell AI Coach what you want to train and get a ready-to-run circuit in seconds. It ships with 224 illustrated exercises, dozens of preset workouts, and week-based streaks with earned freezes — built natively in SwiftUI, localized in nine languages, with no tracking.

It started with a familiar frustration: following a YouTube workout means scrubbing back and forth to see what's next while the trainer talks over your rest. So we built a timer that reads the video for you — then kept going: an AI coach for days without a video, a Watch app so the phone stays down, and streaks that make consistency feel earned.

What makes it different

Paste a YouTube workout

Any workout video becomes a timed, follow-along session — every interval mapped, every switch called with voice and haptics.

AI Coach

Describe the session you want and get a ready-to-run circuit in seconds, with inline AI edits for any exercise or timing in the builder.

Built for the wrist

A full Apple Watch app calls every work, rest, and round with taps, so the phone stays in the bag.

Readable at arm’s length

A flat, high-contrast design on a warm cream canvas, centered on a big dial that counts work in orange and rest in green — legible from the far end of a mat.

Momentum that lasts

Week-based streaks with earned freezes, weekly goals, lifetime stats, widgets, and an Instagram-ready share card.
