# Problem solver vs Geometry

The clearest difference is in-app purchases: Problem solver at none against Geometry's 10. Problem solver also leads on iOS requirement (8.0 vs 15.5). Geometry's advantage is ads (none vs shown) and update cadence (every 2 months vs every 6 months). On price and device support there is nothing between them.

Both are free to download. Geometry sells 9 in-app purchases, starting at $3.99 per month. Problem solver asks for nothing beyond the download.

Problem solver ships an update every 6 months, Geometry every 2 months. The most recent releases landed on May 16, 2026 and September 23, 2026 respectively.
