Seconds 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 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 reads your body measurements and year of birth from Health to estimate calories burned. FREE TO TRY, ONE PAYMENT TO UNLOCK - Everything is available from the first launch. Build any timer and run it. - Each timer locks after you run it once. A single in-app purchase removes the lock on every timer you make. SECONDS AND SECONDS PRO - Seconds Pro is the same app, paid once up front, with nothing to unlock. 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.

Time2WOD: a workout timer designed specifically for High Intensity Interval Training (HIIT) and cross-training. What sets Time2WOD apart are the advanced features it provides, making it the perfect companion app for your HIIT routine. - Customize the display of the timer with workout text that is shown below the timer. This is a very useful feature so you can view your HIIT workout routine while the timer is running. - Extremely accurate timing: if your phone dies or you accidentally close the application while a timer is running, it will continue exactly where you left off when you relaunch the app. - Designed to act like the iOS Music application, the app provides a familiar interface that all users will recognize. Tap the "Launch" button from your list of timers to start using a timer. Simply swipe down to hide the current timer and use the floating bar interface to manage its properties. - Circular timer progress provides an easy way to view how much time is left for the current workout. A single tap inside the progress circle will pause or resume the timer. - Options to enable a beep or vibrate notification that will fire during key moments of the timer. - For interval and tabata timers, you can enable the text-to-speech feature to have the current interval read to the user. This is useful when connected to headphones or a speaker so you can be notified of what is next in the timer. - Powerful search features allowing you to filter the timers based on the title or what is included in the workout. Like other workout timers available for iOS, Time2WOD includes enough basic functionality for any type of athlete. With this application, you can create 4 different types of timers: - Count Up: a simple timer that starts at 0:00 and counts up, either indefinitely or until a specified cutoff time. - Count Down: another simple timer that starts at a user-specified time and counts down to 0:00. - Interval: a more powerful timer that allows a user to create one or more intervals that will each count down to 0:00. You can set a particular interval to repeat or have all intervals repeat allowing for infinite possibilities. - Tabata: a single tabata is 20 seconds of work followed by 10 seconds of rest, repeated for 8 cycles (consuming a total of 4 minutes). You can create multiple tabatas that run sequentially, and optionally add additional rest time in between each tabata. These powerful features are all part of the FREE experience with Time2WOD. To take things to the next level, you can optionally purchase Time2WOD Rx for the full premium experience. This is a one-time purchase which you can use across all of your devices. With Time2WOD Rx, you will be able to: - Create an unlimited number of fully-customizable timers (with the free version, you are limited to only 3 user timers). - Gain access to a large database of pre-defined HIIT workout timers. This includes over 400 pre-configured timers from different categories like The Benchmark Girls, The Heroes, and The Games / Open. - Backup and restore your timers. Easily move your timers from device to device using Dropbox. Copyright © 2023 Joshua Seltzer. All rights reserved.

Verdict
