Sustainable weight loss isn’t about the strictest app — it’s about the one whose method matches how you actually change. If you just need to count, MyFitnessPal or Lose It! work. If you want targets that adapt automatically, MacroFactor wins. If your problem is behavior, not math, Noom is built for that. Here’s how the major weight-loss apps compare in 2026, with real pricing.
MyFitnessPal: the default calorie counter
MyFitnessPal remains the most popular tracker — 280M+ users and the largest food database (20M items). The free tier handles daily calorie and macro logging; Premium is $79.99/year. The trade-off: that huge database is full of inaccurate user-submitted entries, so your numbers are only as good as the entries you pick.
MacroFactor: best for “set targets and forget”
MacroFactor is the strongest pick for data-driven dieters: it recalculates your calorie and macro goals every week based on your real weight trend, so you never have to guess when to eat less. The food database is fully verified (no junk entries). There’s no free tier — $11.99/month or $71.99/year after a 7-day trial.
Noom: best when behavior is the problem
If counting alone never sticks for you, Noom targets the psychology with daily cognitive-behavioral lessons — the best in class for changing eating habits. It’s the priciest here at roughly $70/month, so it’s worth it specifically for people who need the mindset work, not just a calorie tally.
Lose It! and WeightWatchers: simple and community
Lose It! is the natural MyFitnessPal replacement at a much lower price — Premium is $39.99/year, the most affordable premium option here. WeightWatchers (WW) remains the strongest community option: its Points system simplifies the math, and the workshops drive accountability an app alone can’t.
Side-by-side comparison
| App | Price | Best for |
|---|---|---|
| MyFitnessPal | Free; Premium $79.99/yr | Largest database, simple counting |
| MacroFactor | $11.99/mo or $71.99/yr | Adaptive targets, verified data |
| Noom | ~$70/mo | Behavior change / psychology |
| Lose It! | Premium $39.99/yr | Cheapest simple tracker |
| WeightWatchers | Subscription (Points) | Community & accountability |
Worked example: a 20-pound goal
If you respond to numbers, start free on MyFitnessPal or Lose It! ($39.99/year). If you keep stalling because you don’t know when to adjust, MacroFactor’s weekly recalibration ($71.99/year) is worth the upgrade. If you’ve counted before and always rebounded, that’s a behavior signal — Noom’s lessons target exactly that.
What to expect realistically
Every app here works if you log honestly — the app is a mirror, not magic. Pick the method that fits your failure point (math, consistency, or psychology) rather than the most expensive one, and weigh on a trend, not a single day.
Frequently asked questions
Free or paid weight-loss app?
Free (MyFitnessPal/Lose It! basic) is enough to start. Pay only for adaptive targets (MacroFactor) or behavior coaching (Noom) if simple counting hasn’t worked.
Why are my MyFitnessPal numbers off?
User-submitted entries can be inaccurate — pick verified entries, or use a verified-database app like MacroFactor or Cronometer.
Is Noom worth $70/month?
Only if your barrier is behavioral; for pure calorie tracking it’s overkill versus cheaper apps.
