Verdict
The clearest difference is review sentiment: Subintervals at 100% against Slid's 49%. Subintervals also leads on rating (5.0 vs 4.4). Slid's advantage is ratings volume (118 vs 2). On price, update cadence, ads and in-app purchases 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. Slid sells 10 in-app purchases, starting at $0.99 per 7 days and Subintervals sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Subintervals holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Slid has 118 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 49% of Slid's written reviews are positive against 100% of Subintervals's.
Both ship on a similar rhythm, roughly weekly. Both last shipped on October 24, 2026.
