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.

Lock Screen countdown, fixed for real.
• The big number on your Lock Screen and in the Dynamic Island now counts down every second of every interval — including 2- and 3-minute rounds, which used to sit on a static "3 min".
• A TOTAL line shows the time left in the whole workout and keeps counting on its own, so the banner stays honest even when your phone is locked for the entire session.
• Updates to the Lock Screen are now sent in a way iOS accepts from a running workout; if you ever saw the banner freeze at 0:00 or dim to "Open Mariabs" mid-workout, this is for you.
On iPhones with an Always-On display, iOS shows timer seconds as "--" while the screen is dimmed. That's the system's rendering, the same as Apple's own Timer; wake the screen and it ticks.
