This update is all about reliability: • If you pause a workout yourself, a brief interruption like a phone call or Siri no longer makes it restart on its own. • You can now change settings or load a preset right after a workout finishes — no need to tap Reset first. • Smoother, more dependable Lock Screen Live Activity.

Lock-screen polish, workout presets, and German/Spanish/French support. • The lock-screen Live Activity no longer lingers after you close the app, and the countdown stays smooth between phases. • Save your favorite workouts as presets — Tabata, Boxing, EMOM, and HIIT come ready to go; add your own with one tap. • The app now speaks German, Spanish, and French — voice cues, on-screen labels, and the Live Activity all follow your device language. • Also includes iPad support, a standalone Apple Watch app, and auto-pause when your Bluetooth headphones disconnect.

Lock screen polish + home-screen widget + Apple Health + watch complication. • Lock-screen Live Activity no longer lingers after a workout ends or the app is closed. The countdown stays smooth across all phases. • Tap the new Stop button on the lock screen to end a workout without unlocking your phone. • Add the Mariabs 2x2 widget to your home screen for one-tap workout start. • Completed workouts can be saved to the Health app as High Intensity Interval Training sessions (opt-in; only duration is written, no biometrics are read). • Pick Mariabs as a watch face complication in circular, corner, rectangular, or inline slots.

Accessibility, audio, and standby polish. • Auto-pause and resume if a phone call, FaceTime, or Siri interrupts your workout. • Honors Reduce Motion in iOS Accessibility settings. • Larger Text setting now scales the configuration list. • VoiceOver reads phase and remaining time on the play button. • Lock-screen Live Activity optimized for StandBy and Always-On Display: brighter phase color, bolder counter, less visual noise. • Now runs on iOS 16.2 and up.

Polishes the lock screen Live Activity rendering. • Per-second countdown on the lock screen during each phase. • Smooth transition between phases. Counter never sticks at 0:00 between Prepare, Work, Rest and Block Rest. • Progress bar fills in lockstep with the counter.

Fixes a lock screen Live Activity countdown that could stall mid-workout. • The on-screen timer now ticks continuously through every phase, anchored to the workout's total runtime. • Apple Watch and iPhone settings stay in sync. • Small stability and timing polish.

v1.5 — now Mariabs. • Lock Screen Live Activity: a live, ticking countdown that follows your workout through Prepare, Work, Rest, and Block Rest — driven by the system clock so it stays in sync even if the app sleeps. • Apple Watch companion: adjust all six settings (Prepare, Work, Rest, Cycles, Blocks, Block Rest) from your wrist. Settings sync both ways. • Refreshed brand and store listing. • Stability and timing polish.

You can now adjust your interval settings directly on Apple Watch — same six controls as iPhone, all on your wrist. Plus a sync polish that prevents settings from briefly cycling between devices on launch.

Apple Watch companion. Start, pause, and run interval workouts from your wrist — same chimes, same haptics, settings synced automatically from your iPhone.
