# PIECO vs Algorithms

The clearest difference is in-app purchases: PIECO at none against Algorithms's 3. PIECO also leads on review sentiment (100% vs 79%). Algorithms's advantage is update cadence (every 3 weeks vs every 3 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Algorithms sells 3 one-off in-app purchases. PIECO asks for nothing beyond the download.

PIECO ships an update every 3 months, Algorithms every 3 weeks. The most recent releases landed on October 9, 2026 and October 5, 2026 respectively.
