## Description

**Seconds Pro** is a flexible interval timer for HIIT, Tabata, EMOM, circuit training and any workout built from timed intervals. Create workouts from templates or from scratch using sets, rounds and custom intervals. Chain warm-ups, main sets and cool-downs together, color-code intervals, and share timers with friends.

Train without watching your screen using voice cues, countdown warnings, beeps and bells. The timer runs in the background and supports your own music, with cues automatically lowering the volume. Seconds Pro works on iPhone, iPad and Apple Watch, including standalone watch workouts and Quick Intervals. It also includes stopwatch and countdown modes, full-screen displays, a lock button, and Apple Health workout and mindful-session logging. Paid once with all features included—no recurring subscription or unlocks.

## Review summary

Overall, Seconds Pro is praised for its high customizability, class-ready workflows, and a straightforward, low-friction experience, plus a one-time purchase model and solid backups. However, multiple reviews report recurring reliability problems with Apple Watch syncing and complications, timing glitches during workouts, and occasional failures to save workouts to Health data, especially after updates. These issues can disrupt live sessions, though the core features remain valuable for planning and delivering timed workouts. The app shows strong potential with continued stability improvements on watchOS and iOS.

### Pros

- Highly customizable timers and routines; easy to set up.
- Great for workouts and group classes; ideal for trainers.
- Robust backups and data recovery; cross-device syncing (iCloud) and offline functionality.
- One-time purchase with no ongoing subscription.
- Simple, intuitive interface with large clear controls.

### Cons

- Unreliable Apple Watch integration and complications; syncing issues and difficulties adding to watch faces.
- Timing glitches: beep irregularities and countdown inaccuracies.
- Saving workouts/Health data can hang or fail at the end of a session.
- Stability issues after OS/watch updates; occasional crashes and sync failures.
