## What is Mariabs · Interval Timer?

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. Your settings stay on your device. The privacy policy is one page; you can read it before you tap install.

NO ADS
Mari has no ads, no in-app purchases, and no premium tier. No account required.


## Version history (last 5 releases)

### 1.12.1 — 2026-09-03

Interval navigation replaces the 30-second scrub: one tap back restarts the work, rest or prepare period you're in, one tap forward jumps to the next. Tapping back twice steps to the previous interval.

Fixed: on the Lock Screen, intervals longer than a minute no longer sit on a stuck “2:--”. iOS can't count seconds in real time across a range that long, so long intervals now show the minutes left and switch to seconds for the final minute — and the progress ring keeps moving throughout, including in Always-On.

Fixed: pause and play on the Lock Screen now work even after iOS has closed the app in the background — your workout is picked up exactly where it was.

Fixed: the post-workout share card now actually appears in the share screen.

New: an Apple Health section on the main screen shows that finished workouts are saved to Apple Health as high-intensity interval training, and lets you turn that off.

### 1.12 — 2026-08-20

Skip forward and back 30 seconds at a time, while the timer is running or paused. The buttons sit either side of play.

Reset has moved to the top-right corner. It used to sit right under play, which made it far too easy to graze when pausing.

Small thing: the Mariabs wordmark now has a rule under it.

### 1.11 — 2026-08-14

Share your workout when you finish. Pick a photo and Mariabs lays the session's numbers over it — straight to Instagram Stories, or any other app.

The Lock Screen no longer keeps counting a workout that has ended. If you force-quit mid-session, the banner now goes quiet instead of ticking down a workout that isn't running.

### 1.10 — 2026-07-26

Your saved workouts, front and center:

• A new bookmark button sits right beside Play — your presets are one tap away.
• The Lock Screen now shows which preset you're running ("BOXING 3×3", not just "Workout").
• Pause and resume straight from the Lock Screen, without unlocking.
• Stopping now takes two taps — no more accidentally killing a workout with a stray touch.
• Rename and reorder your presets (swipe to rename, Edit to drag).

### 1.9 — 2026-07-24

The Lock Screen timer now counts the way you'd expect:

• The big countdown follows the current interval, ticking every second.
• Total time left in the workout is shown in minutes alongside cycle and block.

(iOS only ticks Lock Screen timers second-by-second inside the final minute — the previous whole-workout countdown could appear stuck as "18:--". The new layout works with that rule instead of against it.)
