YAZIO vs MyFitnessPal vs Noom: which app fits?

Start with what you want the app to ask of you. Choose YAZIO if nutrition planning and activity records feel useful; choose MyFitnessPal if you want detailed food records; choose How It Felt if you want a reflective journal without nutrition numbers. The Noom details linked on this page need checking against its current offering before you decide. If tracking or another app feature feels activating during eating-disorder recovery, a clinician's guidance comes first. How It Felt keeps photos, note text and the local database on your device, while selected entry-derived fields may go to Firebase and AdMob and RevenueCat process service data. You are allowed to use none of them.

When to pick which

Pick YAZIO vs MyFitnessPal vs Noom if…

YAZIO may suit you when nutrition planning and its tracking tools feel neutral and useful.
MyFitnessPal may suit you when detailed food or activity records feel supportive rather than demanding.
Review the linked Noom pages if you are considering that service; confirm its current offering, price and privacy terms first.
Read each service's current plan and privacy details before signing up.

Pick How It Felt if…

You want an on-device journal rather than a structured programme.
You want to notice hunger, fullness, emotion or sensation without turning the entry into a number.
You prefer no account and no external target to maintain.

Verdict

YAZIO and MyFitnessPal offer structured records, while the linked Noom offering should be checked on its current pages. How It Felt leaves more room around the experience itself: an on-device journal with no assigned outcome. None is automatically best. Choose the approach that leaves you feeling supported, and pause any app that makes eating feel like a test.

Frequently asked

What is the main difference between these apps?

YAZIO focuses on nutrition planning and tracking. MyFitnessPal focuses on a detailed food and activity diary. Check the linked Noom pages for its current offering. How It Felt is an on-device journal for reflection without nutrition numbers or a programme.

Is How It Felt another food-tracking app?

No. It does not calculate nutrition values or set a progress target. You can note how a meal felt in your body and mind, or choose not to record it.

Which app is most private?

This page does not rank them. How It Felt does not require an account. Photos, note text and the local database stay on-device, but the privacy policy says selected entry-derived fields — including meal type, emotion, hunger level, photo presence and note length — may be sent to Firebase, while AdMob and RevenueCat also process service data. Review every service's current disclosures for your plan and region.

Can I use How It Felt with one of these apps?

Only if the combination feels supportive. How It Felt does not import or judge another app's data. If tracking or coaching increases pressure, pausing is a valid choice.

Are these consumer apps a substitute for medical treatment?

This comparison does not assess any of these services as medical treatment. How It Felt is a self-reflection journal, not a clinical tool. Consumer apps are not a substitute for assessment or treatment; if eating, hunger, fullness or body image is causing distress, speak with an eating-disorder-informed clinician.
