"This isn't just another timer app. This is your favorite timer app's favorite timer app" - Cody Lee, iDownloadBlog. "What I like most about TimeWave, though, is its clean, black-and-white design" - John Voorhees, MacStories. "Liquid Glass really comes to life on its widgets" - Michael Burkhardt, 9to5Mac. "Best iPhone Apps of July, 2021" - Beau Hamilton, Slashdot. WHAT CAN YOU DO WITH TIMEWAVE? TimeWave allows you to combine your breathwork app, your workout app, your focus timer, cooking timer and much more into one single app. You can use TimeWave for: • Breathwork — build custom breathing flows like 4-7-8 Breathing to lower blood pressure, Physiological Sigh to reduce stress and anxiety, Wim Hof Breathing to increase alertness, Box Breathing to relax and much more. • Intermittent Fasting — Create your own intermittent fasting using various splits like 16:8, 12:12, 5:2, etc. You can create timer-splits for each day or for the entire week. • Workout Routines — create your own workouts by chaining excercise and break durations. You can make Tabata/HIIT workouts or even yoga routines. • 20-20-20 Rule — create a timewave to follow the 20-20-20 rule (Every 20 minutes look at something 20 ft away for 20 seconds) while working with screens to prevent eye-strain. • Focus Timers — create pomodoro timers or any kind of work-break timewaves. You are not restricted to 25 minute session, you can create any sequence that suits your preferences. • Cooking — ever had to keep resetting your timers after each whistle? well, now you wont have to. Just create a timewave for each recipe. • Everything — anything else that involves timed sequential tasks. SPECIAL FEATURES: • TimeWave A.I — TimeWave will tell you what has to be done for how long while the Calibre is running. For eg: "Breathe In For 4 Seconds" so you don't have to look at the screen. • iCloud Sync — Available on Mac, iPad, iPhone and Apple Watch and keeps everything up-to to date on all your devices with iCloud Sync. • Black & White UI — B&W is a lot of colours. If you are anything like us, you'll love our ironically modern black and white UI. MORE: • Personal touch — a hand-crafted Indie app. If you have any questions or feedback, you can reach out to us at timewave.team@gmail.com Privacy Policy: https://timewaveapp.com/privacy Terms of Use: https://timewaveapp.com/terms

Verdict
The clearest difference is rating: Interval Timer at 4.6 against Chain Timers's 4.0. Interval Timer also leads on ratings volume (25 vs 1) and update cadence (every 3 weeks vs every 6 weeks). Chain Timers's advantage is in-app purchases (none vs 3) and review sentiment (100% vs 86%). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Interval Timer sells 3 in-app purchases, starting at $4.99 per month. Chain Timers asks for nothing beyond the download.
Interval Timer holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Interval Timer has 25 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 86% of Interval Timer's written reviews are positive against 100% of Chain Timers's, so the app with the better star average is not the one people write more warmly about.
Interval Timer ships an update every 3 weeks, Chain Timers every 6 weeks. The most recent releases landed on October 9, 2026 and September 23, 2026 respectively.
