# Quickgrind vs Thread Chart

The clearest difference is in-app purchases: Quickgrind at none against Thread Chart's 1. Thread Chart's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 18.0). On price and ads there is nothing between them.

Both are free to download. Thread Chart sells 1 one-off in-app purchase. Quickgrind asks for nothing beyond the download.
