Verdict
The clearest difference is price: SupplementApp at Free against SimpleHR's $0.99. SupplementApp also leads on iOS requirement (12.0 vs 17.0). SimpleHR's advantage is rating (4.0 vs 3.7) and update cadence (every 4 months vs every 10 months). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.

SupplementApp is free to download; SimpleHR costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
SimpleHR holds the better App Store score, 4.0 against 3.7. Both are backed by a comparable volume of ratings — 13 and 6 respectively. Written reviews complicate that: 43% of SimpleHR's written reviews are positive against 50% of SupplementApp's, so the app with the better star average is not the one people write more warmly about.
SimpleHR ships an update every 4 months, SupplementApp every 10 months. The most recent releases landed on October 4, 2026 and September 24, 2026 respectively.
