# Math Games vs OpenDay

The clearest difference is in-app purchases: OpenDay at none against Math Games's 1. OpenDay also leads on ads (none vs shown). Math Games's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.5). On price and update cadence there is nothing between them.

Both are free to download. Math Games sells 1 one-off in-app purchase. OpenDay asks for nothing beyond the download.

Math Games ships an update every 2 weeks, OpenDay fortnightly. The most recent releases landed on November 8, 2026 and November 5, 2026 respectively.
