# iDoctor vs Bolt Stack

iDoctor and Bolt Stack both sit at 5.0 stars, but that hides the real split: 100% of Bolt Stack's written reviews are positive against 22% of iDoctor's. Bolt Stack also leads on update cadence (every 8 days vs every 105 months) and ratings volume (65 vs 1). iDoctor's advantage is ads (none vs shown). On price, rating, in-app purchases and monetization model there is nothing between them.
