# LoopTodo vs Formula Lab

The clearest difference is in-app purchases: LoopTodo at none against Formula Lab's 1. LoopTodo also leads on ads (none vs shown). Formula Lab's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 26.0). On price there is nothing between them.

Both are free to download. Formula Lab sells 1 in-app purchase, starting at $1.99 per month. LoopTodo asks for nothing beyond the download.
