# picocalc vs ScheduledList Countdown

The clearest difference is update cadence: ScheduledList Countdown at every 2 months against picocalc's every 16 months. ScheduledList Countdown also leads on review sentiment (80% vs 66%) and iOS requirement (10.0 vs 17.6). picocalc's advantage is monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.8). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. picocalc sells 1 one-off in-app purchase and ScheduledList Countdown sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

picocalc holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 3 and 5 respectively. Written reviews complicate that: 66% of picocalc's written reviews are positive against 80% of ScheduledList Countdown's, so the app with the better star average is not the one people write more warmly about.

picocalc ships an update every 16 months, ScheduledList Countdown every 2 months. The most recent releases landed on October 31, 2026 and November 1, 2026 respectively.
