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.

Side by side.

This is Fettle.

MyFitnessPal records what you ate. Fettle plans what you’ll eat, moves your targets each week, and turns the plan into a shop.

A calorie target set in week one is wrong by week six — the body it was calculated for no longer exists. So people do everything right, stall anyway, and blame themselves. The plateau isn’t a discipline failure. It’s a tooling failure.

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.
