# Puzzelfit vs SUM

The clearest difference is in-app purchases: Puzzelfit at none against SUM's 1. SUM's advantage is ads (none vs shown) and update cadence (every 3 days vs every 2 weeks). On price, device support and iOS requirement there is nothing between them.

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

Puzzelfit ships an update every 2 weeks, SUM every 3 days. The most recent releases landed on October 11, 2026 and October 2, 2026 respectively.
