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 with iOS 26's Liquid Glass design, 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.

Liquid Glass throughout

An early, thorough adoption of iOS 26's design language, centered on a big glass dial that counts work in orange and rest in green.

Momentum that lasts

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