Mariabs · Interval Timer

Tabata, HIIT and EMOM timer

Free · Designed for iPad. Not verified for macOS.

Mariabs 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. Mariabs 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 whatever you're already listening to — music, podcasts, anything — and lowers it only for the moment Mariabs 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 Mariabs collects nothing. No account. No email. No analytics. No tracking. Your settings stay on your device. The privacy policy is one page; you can read it before you tap install. NO ADS Mariabs has no ads, no in-app purchases, and no premium tier. No account required.

  • This app has not received enough ratings or reviews to display an overview.

Lock Screen and stability release. • The Lock Screen now shows the right phase at every interval change, even when iOS delays the app's update — the next phase is already on the banner and takes over on time. • Resuming from the Lock Screen shows the running workout straight away, and the pause button always does what it shows. • If the phone was busy and the app fell behind, it now catches up to where your workout should be instead of drifting. • New: switch off the voice cues in SOUND. Chimes and the 3-2-1 countdown stay. • Changing settings on Apple Watch while a workout runs on iPhone no longer alters the running workout; the change applies when you're done. • Fixed a crash that could occur when Bluetooth headphones disconnected mid-workout or when resuming from the Lock Screen after the app had been closed. • Workouts resumed after a relaunch are now saved to Apple Health with their real start time. • Apple Watch keeps the workout alive even if you paused during the Health permission prompt. • Clearer Apple Health wording, better VoiceOver support on the timer dial and steppers, and localized widget descriptions.
