Seconds Pro is an interval timer for HIIT, Tabata, EMOM, circuits and any workout built from timed intervals. It calls each interval out loud, keeps running with the screen off, and runs on iPhone, iPad and Apple Watch. Apple has featured it, and Joe Wicks, The Body Coach, has said it is the fitness app he uses more than any other. BUILD ANY WORKOUT - Start from a HIIT, Tabata or circuit template, or build a timer from scratch with sets, rounds and intervals of different lengths. - Chain timers into one compound timer, so a warm-up flows into the main set and then a cool-down. - Color-code every interval so you know what is coming before the beep. - Share a timer with a friend in one tap. HEAR IT, DON'T WATCH IT - Voice cues call out each interval by name and warn you before the next one starts. - Beeps and bells are there too if you would rather not be talked at. - Play your own music, per timer or per interval. Cues duck the music and it comes back up when they are done. - The timer keeps going in the background while you use other apps or the screen sleeps. ON THE GYM FLOOR - A full-screen, color-coded display you can read from across the room, in portrait or landscape. On iPad it uses the whole screen. - A lock button stops a stray tap from pausing your set. APPLE WATCH - Seconds Pro runs on the watch by itself, so the phone can stay in the locker. Timers you build on the phone sync to the wrist, and Quick Intervals builds a basic circuit on the watch itself. MORE TIMERS - A stopwatch that marks your best and worst laps. - A countdown timer with five preset durations (three on Apple Watch). APPLE HEALTH - Save workouts and mindful sessions to Health. With a heart rate monitor connected, Seconds Pro reads your body measurements and year of birth from Health to estimate calories burned. PAID ONCE, NOTHING TO UNLOCK - Seconds Pro is paid for up front. Every feature is included and every timer you make can be run as many times as you like. SECONDS AND SECONDS PRO - Seconds is the free version of this app. It has the same features, but each timer locks after one run until a single in-app purchase unlocks it. The two are separate products and a purchase in one does not carry over to the other. If you bought Seconds Pro, download Seconds Pro. If you bought the unlock in Seconds, download Seconds and use Restore Purchases.

Verdict

The call

The clearest difference is review sentiment: Seconds Pro Interval Timer at 80% against Burnd's 0%. Seconds Pro Interval Timer also leads on in-app purchases (none vs 3) and ratings volume (12K vs 1). Burnd's advantage is price (Free vs $7.99) and update cadence (every 4 days vs fortnightly). On ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Burnd holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Seconds Pro Interval Timer has 12K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of Seconds Pro Interval Timer's written reviews are positive against 0% of Burnd's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Seconds Pro Interval Timer ships an update fortnightly, Burnd every 4 days. The most recent releases landed on September 24, 2026 and September 16, 2026 respectively.
