# MindKeep vs ThinkByte

The clearest difference is review sentiment: MindKeep at 100% against ThinkByte's 50%. MindKeep also leads on rating (5.0 vs 4.1). ThinkByte's advantage is ads (none vs shown) and device support (3 vs 1). On price, ratings volume, update cadence and in-app purchases there is nothing between them.
