I tested 5 calorie trackers for a month - results
I used 5 different calorie tracking apps simultaneously for 30 days while weighing all food on a scale as ground truth.
Apps tested: MyFitnessPal (free), Cronometer (premium), PlateLens (free), MacroFactor (paid), Lose It! (free)
Database accuracy vs food scale:
- Cronometer: ±4%
- MacroFactor: ±6%
- PlateLens: ±7% (manual), ±12% (photo only)
- MFP: ±9% (highly variable — some user entries way off)
- Lose It!: ±8%
Ease of logging (1-10):
- PlateLens: 9/10
- Lose It!: 7/10
- MacroFactor: 7/10
- MFP: 6/10
- Cronometer: 5/10
Verdict: Accuracy #1 = Cronometer. Convenience #1 = PlateLens. Smartest algorithm = MacroFactor. MFP is living off its reputation.
This is the content I come to this forum for. Incredible work. The ±12% for PlateLens photo-only is better than I would have guessed.
MFP database variability is a real problem. User-submitted entries can be off by 50%+ because someone entered it wrong.
Ease of logging is such an underrated metric. The best app is the one you actually use consistently.
Excellent methodology. PlateLens's photo accuracy will likely keep improving as their AI model gets better. The other apps don't have that improvement vector.
MFP scoring lowest on ease of use despite being the most "established" is really telling.
As a beginner this is SO helpful. I'll stick with PlateLens for ease of use. Maybe switch to Cronometer later for micros.
The hero we needed. Bookmarking this.
RIP MyFitnessPal 2005-2022. It had a good run.
Did you notice any difference in how the apps handled homemade recipes?
@healthyHannah Cronometer and MFP have the best recipe builders. PlateLens has one too but it's newer. For homemade stuff I'd still use Cronometer.
