Overview

Intertakt is an interval timer for HIIT, Tabata, and rounds-based workouts, built around audio cues rather than a visible display. Settings are set up once, then a session starts with one tap and the phone can be laid face-down, locked, or put in a pocket. Beeps and a voice announce phases, rounds, and the halfway mark over whatever music is playing, and the volume for music, voice, and cues can be set independently.

The product is designed to survive interruptions: lock screens, app switches, and incoming calls pause the session, which resumes from where it stopped. Intervals are set in whole seconds so each exercise can have its own time, and plans are saved by name and autosaved as they are edited. Presets include Tabata 20/10, HIIT, a desk break, and a mobility routine.

The site states there are no ads and no accounts, with settings and plans stored on the device. The free tier offers unlimited sessions, all presets, and up to three custom plans. A one-time Premium purchase adds unlimited custom plans, session history, and export and import of plans as files. The Android app is listed as coming soon to Google Play, with iOS planned.
