# Summa vs SUM

The clearest difference is in-app purchases: Summa at none against SUM's 1. SUM's advantage is update cadence (every 3 days vs every 6 weeks) and iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. SUM sells 1 one-off in-app purchase. Summa asks for nothing beyond the download.

Summa ships an update every 6 weeks, SUM every 3 days. Both last shipped on October 31, 2026.
