Prime Timed was made for those who wanted a simple interval timer app — but also love deep sound customization for rounds as well as personal training programs utilizing voice to create the workouts. Use it as plain as a stopwatch, or go as deep as you like. It can be as simple or as complex as you need. Live widget and privacy focused. START IN SECONDS Pick from a list, hit Start. Huge, readable numbers and round names you can see from across the room, with color-coded Work, Rest, and Get Ready screens. READY-MADE TIMERS INCLUDED Popular HIIT and Tabata protocols are already set up — Tabata Classic, 30/30, 40/20, 45/15, 50/10, EMOM, AMRAP, sprint intervals, and more — plus boxing rounds, Muay Thai and MMA rounds, CrossFit benchmarks (Murph, Fight Gone Bad, Fran), and a full set of jiu jitsu competition-prep timers built on standard match times for every belt, from White through Black, along with ADCC-style rounds. SOUND CUSTOMIZATION THAT GOES DEEP • A distinct sound for every moment: work start, rest, finish, beginning countdown, round countdown, and a round-ending warning — each with its own volume. • Record your own voice, or import audio, right inside the app. Every sound you add is available everywhere. • Timed Sounds: play any sound at an exact second of any round — into the round, before it ends, before it starts, even before the whole workout's countdown. Pick exactly which rounds it plays in. • Inspirational Sounds: build a pool of clips that play at random intervals during work — motivation that never gets stale. • Pause-while-playing: freeze the clock while an instruction plays, then resume automatically. Perfect for coached drills. • Music-friendly: your playlist keeps playing; Prime Timed can duck it under cues and bring it right back. DON'T LIKE THE COLOR OR FONT • Now a font selection system in the settings menu that allows you to pick from a number of fonts that change not only the system font but, the timer fonts as well. • Don't like the default color scheme then you can pick from a number of them or completely customize it to your liking MADE FOR TRAINERS Personal trainers of any kind: record your own voice giving commands at any interval, in any round. Build a coached session once — "switch sides," "last ten seconds," "water break" — and it runs itself. SHARE EVERYTHING Send a timer to anyone and it arrives complete — settings AND your custom recorded sounds travel with it. Build once, share with your whole gym.

Verdict
The clearest difference is price: Somnee at Free against Prime Timed's $0.99. Somnee also leads on ratings volume (71 vs 3) and iOS requirement (15.1 vs 17.0). Prime Timed's advantage is rating (5.0 vs 3.6) and update cadence (every 2 days vs every 2 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
