Verdict
The clearest difference is review sentiment: Kasa Smart at 82% against PurrSong's 26%. Kasa Smart also leads on rating (4.8 vs 2.3) and ratings volume (81K vs 4). PurrSong's advantage is update cadence (every 9 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Kasa Smart sells 8 in-app purchases, starting at $2.99 per month and PurrSong sells 3 in-app purchases, starting at $2.90 per month. Whichever you choose, the download price is not the number that matters.
Kasa Smart holds the better App Store score, 4.8 against 2.3.

Written reviews point the same way: 82% of Kasa Smart's written reviews are positive against 26% of PurrSong's.
Kasa Smart ships an update every 3 weeks, PurrSong every 9 days. The most recent releases landed on November 9, 2026 and November 7, 2026 respectively.
