Credit where due: MyFitnessPal has the largest food database in the industry, two decades of brand trust, and its free tier — though much reduced since barcode scanning moved behind the paywall — still lets you log meals at no cost. If all you want is a diary, it remains a reasonable one.
The philosophical difference is what happens after you log. MyFitnessPal records; the target you set on day one sits still until you change it. Fettle plans your meals in advance, recalculates your targets every week from your weigh-in trend, explains each change, and turns the plan into a ready-to-buy grocery checkout. One is bookkeeping. The other is coaching.
MyFitnessPal prices are published US App Store prices as of July 2026; UK pricing varies by store. Feature availability may change — corrections welcome via our contact form.
This is Fettle.

One-tap grocery checkout

Adaptive engine · targets recalculated weekly
Choose MyFitnessPal if…
You want a free diary and don’t mind ads or manual macro maths
You eat lots of niche packaged foods and want the biggest database
You already know your targets and just want to count against them
Choose Fettle if…
You’ve stalled before and never knew why — you want targets that adapt weekly
You want to be told what to eat, not just what you ate
You want the week’s food decided, shopped and delivered in one tap
You want every change explained, not a silent number
The short version
MyFitnessPal is a very good ledger. Fettle is a coach with a shopping trolley. If logging alone worked, you probably wouldn’t be reading this page.
