IntervalBeats vs Mariabs · Interval Timer

IntervalBeats is a focused interval timer for workouts, HIIT, tabata, stretching, meditation, and anything else that benefits from structured time. Built around Apple Music — pick your intervals, choose a work playlist and a rest playlist, press start. APPLE MUSIC — RECOMMENDED FOR THE FULL EXPERIENCE Apple Music is the smoothest path. Connect once and IntervalBeats plays, pauses, and switches between your work and rest playlists automatically — even while the screen is locked. The Sleep Timer pauses Apple Music precisely at zero whether your phone is locked or not. Requires an Apple Music subscription. WORKS WITH OTHER AUDIO APPS TOO Prefer Spotify, Apple Podcasts, Overcast, Audible, or YouTube Music? Start playing in your audio app, then launch an IntervalBeats session — your audio mixes with our beep cues. Workout auto-pause and the Sleep Timer also work with these apps; just keep IntervalBeats on screen (we dim it for you) so iOS allows us to send the pause. No Apple Music subscription needed.

Mari is a sharp, minimal interval timer for anyone who trains in rounds — tabata, HIIT, EMOM, circuits, or your own custom intervals. Set your prepare, work, rest, cycles, blocks, and block-rest durations in seconds. Press the white play button. Mari counts you in, calls out each phase, and chimes the final 3-2-1 of every interval so you can keep your eyes on what you're doing instead of on the screen. WHAT YOU GET • Six adjustable parameters: prepare, work, rest, cycles per block, number of blocks, and rest between blocks • Voice cues for every transition: "Prepare", "Work", "Rest", and "Block complete — get ready for the next" • Distinct musical chimes per phase, generated on-device, synced with light haptics • 3-2-1 countdown ticks before each phase change • Big, monochrome timer dial with a subtle progress ring tinted to the current phase • Cycle and block progress shown at all times so you always know where you are • Plays over your music — Spotify, Apple Music, podcasts — and ducks them only when Mari speaks • Stays awake automatically while a workout is running • Settings remembered between launches DESIGNED TO STAY OUT OF THE WAY The screen is dark, glanceable from across a gym, and built around one button. There are no menus, no levels, no streaks, no badges, no analytics. You configure once, then press play. PRIVACY Mari collects nothing. No account. No email. No analytics. No tracking.
