Verdict
S2 and WORKIT both sit at 4.1 stars, but that hides the real split: 60% of WORKIT's written reviews are positive against 41% of S2's. WORKIT also leads on device support (3 vs 1) and iOS requirement (9.0 vs 16.0). On price, rating, ratings volume and update cadence 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. S2 sells 2 in-app purchases, starting at $22.99 per year and WORKIT sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
S2 holds the better App Store score, 4.1 against 3.9. Both are backed by a comparable volume of ratings — 126 and 74 respectively. Written reviews complicate that: 41% of S2's written reviews are positive against 60% of WORKIT's, so the app with the better star average is not the one people write more warmly about.
S2 ships an update fortnightly, WORKIT every 2 weeks. Both last shipped on October 12, 2026.
