Verdict
The clearest difference is in-app purchases: Stairs at none against 99 Problems's 1. Stairs also leads on ratings volume (24K vs 38) and rating (4.6 vs 4.3). 99 Problems's advantage is ads (none vs shown) and iOS requirement (6.1 vs 13.0). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. 99 Problems sells 1 one-off in-app purchase. Stairs asks for nothing beyond the download.
Stairs holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Stairs has 24K ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 74% of 99 Problems's written reviews are positive against 68% of Stairs's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on September 7, 2026 and September 26, 2026 respectively.
