# Sandflow vs PK10000

The clearest difference is rating: PK10000 at 4.3 against Sandflow's 3.5. PK10000 also leads on iOS requirement (15.2 vs 17.0). Sandflow's advantage is review sentiment (71% vs 55%) and update cadence (every 9 days vs every 3 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Sandflow sells 5 in-app purchases, starting at $3.99 per month and PK10000 sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

PK10000 holds the better App Store score, 4.3 against 3.5. Both are backed by a comparable volume of ratings — 10 and 6 respectively. Written reviews complicate that: 71% of Sandflow's written reviews are positive against 55% of PK10000's, so the app with the better star average is not the one people write more warmly about.

Sandflow ships an update every 9 days, PK10000 every 3 weeks. The most recent releases landed on September 26, 2026 and August 18, 2026 respectively.
