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 NEW IN 2.0: RUN MODE Switch from TIMER to RUN and Mariabs measures your run with GPS. • Just run: distance, pace, time and your route on a map, with an optional time goal and/or distance goal • Run / walk: run and walk intervals on top of the run (default run 4:00, walk 1:00 × 6), spoken over your music • Your split for every kilometre (or mile) is called out with its pace • Lock Screen and Dynamic Island show the countdown, distance and pace • Save or discard each run. Saved runs stay on your iPhone, with map and splits, and can be exported as GPX • No account, nothing uploaded. Runs are not written to Apple Health 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, runs and routes stay on your device. Location is used only during a run. 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.
