# Geometric Sequence vs Atomic Tab

The clearest difference is in-app purchases: Geometric Sequence at none against Atomic Tab's 1. Geometric Sequence also leads on ads (none vs shown) and iOS requirement (12.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Atomic Tab sells 1 one-off in-app purchase. Geometric Sequence asks for nothing beyond the download.
