Features & Capabilities

JAB – Boxing Interval Timer

JAB is a free, modern timer designed for boxing, workouts and other sports. It features a clean, intuitive interface with flexible round timings (prepare, warning, intense, rest), clear sound and light signals, and hands-free Siri control to keep your focus on the work. Music integration lets you listen to Apple Music or Spotify without leaving the app, making training more enjoyable and efficient.

A standout feature is Intense mode, which divides a round into equal segments for precise interval work. JAB offers ready-made presets for different training sessions, background operation (screen off), and both vertical and horizontal display options. An optional JAB PRO subscription is available via iTunes with auto-renewal; the free version remains fully usable for standard workouts.

User Reviews

Reviewers consistently praise the app as simple, easy to use, and effective for boxing workouts, with useful presets and a positive training aid. However, a major recurring complaint is Spotify/music integration: sufferers report issues linking Spotify, missing playlists, and music being muted during rounds. A smaller but notable grievance is that paying for the full version does not resolve music-related features.
Pros
  • Easy to use; simple, efficient interface
  • Great for training; generally well-regarded and recommended
  • Has presets and adjustable workout settings to avoid constant reconfiguration
Cons
  • Spotify/music integration problems: linking Spotify and playlists not syncing
  • Music playback limitations: music is muted during rounds and third-party music support is limited
  • Paying for the full version does not fix music features or allow adding music
