Scored highest of 30 apps for behavioral strategies in the American Journal of Preventive Medicine. The New York Times called it simpler, quicker, and better-looking than the competition.

Speed: In our January 2026 test, we logged the same 127 foods in every major app over a week. MyNetDiary took 31% fewer taps than the most popular calorie tracker. Results: In a peer-reviewed JMIR study of 5,132 MyNetDiary users (2026), those who tracked food 6-7 days a week lost 11.33% of body weight on average over 6 months.
