Looking for the best diet tracking app for 2025?
We compared popular nutrition and calorie-tracking tools like Cronometer, MacroFactor, Lose It!, YAZIO, Eated, and Hava using Reddit reviews, pricing data, and published clinical evidence — so you can see what actually works, not just what’s trending.
If you’ve ever downloaded a diet app with great intentions — then stopped logging by week three — you’re not alone.
For most of us, it’s not about “more willpower.” It’s about finding a tool that feels supportive, simple, and actually fits your life.
This year, I looked at what people are really saying on Reddit, what the science tells us, and what new tools like Hava are doing with the satiety-per-calorie idea — helping you eat in a way that keeps you full, not frustrated.
What We Compared
We reviewed eight popular diet apps based on:
- Real Reddit feedback (what users love and hate)
- Current UK pricing (2025)
- Clinical evidence from recent studies
- Ease of use and long-term sustainability

Final Thoughts
Key takeaway:
Apps do help—but only if you use them consistently and pair tracking with feedback or coaching.
The most effective tools combine science-based design, ease of use, and psychological support.
- For data precision → Cronometer or MacroFactor
- For simplicity → Lose It! or MyNetDiary
- For habit building → Eated or YAZIO
- For motivation with humour → CalorieDaddy
- For satiety science fans → Hava
Choose the one that makes tracking feel easy—and you’ll already be ahead.
Do diet-tracking apps really work?
Yes — but results are usually modest. Clinical studies show most users lose about 1 – 2.5 kg in the first three to six months if they track consistently.
Apps work best when combined with personalised feedback, coaching, or social support rather than used alone.
📖 Evidence: https://pubmed.ncbi.nlm.nih.gov/39757698/ and https://pmc.ncbi.nlm.nih.gov/articles/PMC4422872/
Which diet-tracking app is best for weight loss?
It depends on your style:
Cronometer / MacroFactor – for accuracy and adaptive feedback
Lose It! / MyNetDiary – for quick, everyday logging
Eated / YAZIO – for gentle habit building
Hava – for a satiety-per-calorie approach that focuses on fullness instead of calorie counting.
What is “Satiety per Calorie”?
“Satiety per Calorie” (SPC) measures how filling a food is for its calorie cost.
Foods higher in protein, fibre, and water—and lower in energy density—score higher on satiety.
Apps like Hava use this science to help you pick foods that keep you full on fewer calories.

Are calorie-tracking apps safe for mental health?
Most users find them motivating, but anyone with a history of eating disorders or obsessive behaviours should use them cautiously.
Look for apps that encourage balanced meals, rest days, and self-compassion (like Eated or MacroFactor).
If tracking becomes stressful, it’s better to step back or seek professional guidance.

How can I get the most out of a diet app?
Log daily, even imperfectly.
Weigh or scan food for accuracy.
Reflect weekly—not obsessively.
Use reminders or streaks to stay consistent.
Focus on progress, not perfection.
Are free diet apps good enough?
Yes — for many people the free versions of Lose It!, MyNetDiary, or Cronometer provide everything needed to start.
Premium upgrades add analytics or coaching, but consistency matters far more than paid features.
