Verdict
The clearest difference is ads: Interval at none against Profast's shown. Interval also leads on iOS requirement (14.0 vs 18.1). On price, in-app purchases 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 sells 3 in-app purchases, starting at $0.99 per 7 days and Profast sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
