Verdict
The clearest difference is ads: Interval Timer at none against TimeFit's shown. Interval Timer also leads on rating (5.0 vs 4.7). TimeFit's advantage is ratings volume (321 vs 2) and update cadence (fortnightly vs monthly). On price, in-app purchases, monetization model 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. TimeFit sells 4 in-app purchases, starting at $3.99 per month and Interval Timer sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Interval Timer holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: TimeFit has 321 ratings behind it against 2, so its average is the more settled of the two.
TimeFit ships an update fortnightly, Interval Timer monthly. The most recent releases landed on October 12, 2026 and September 20, 2026 respectively.
