## What is Interval Timer?

Run every HIIT and Tabata interval from your wrist — no iPhone required.

PERFECT FOR
Tabata, circuit training, CrossFit-style WODs, EMOM blocks, home cardio, and gym sessions where your hands are busy and your phone should stay in the locker.

### 2/5 — Есть проблемы

*2026-08-23*

Слишком мало настроек: нельзя настроить количество полных сетов и отдых между ними. Неудобно переключать варианты таймеров из-за случайных нажатий на настройки. В режиме always on display перестает работать таймер совсем, пользоваться невозможно.

**Developer response:** Здравствуйте!

Спасибо, что написали. В версии 1.1.0, она уже в App Store:

• можно задать число сетов и отдых между ними;
• пресет открывается отдельным списком и больше не меняется от случайного касания;
• на всегда включённом экране отсчёт идёт по часам и не замирает.

Обновитесь до 1.1.0. Если таймер всё ещё останавливается, напишите версию и разрешено ли в приложении «Здоровье» на iPhone сохранять тренировки — без этого сессия не продолжается с опущенным запястьем:
