# Rounds vs CalloutTimer

The clearest difference is in-app purchases: CalloutTimer at none against Rounds's 1. CalloutTimer also leads on ads (none vs shown). Rounds's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.1). On price there is nothing between them.

Both are free to download. Rounds sells 1 one-off in-app purchase. CalloutTimer asks for nothing beyond the download.
