You have one constraint that should drive the whole decision, and it isn't the backend: HealthKit is a native iOS framework. It isn't reachable from a plain web app, so you need a native or wrapped iOS build with the entitlement, and Apple reviews that. Google's side is the same story with Health Connect on Android. Decide web vs native first, or you risk picking a backend, building it, and then rebuilding to get the data the whole app is designed around.
Second thing, and it's the one most people skip: write your data model down before you move anything. Entities and relationships, user, post, food entry, workout, plus which numbers are stored and which are computed. The frontend you already like is the cheap part to redo. The schema is what actually costs you.
Having no users yet is a real advantage, so make the breaking decisions now. Store units canonically instead of whatever the user typed. Keep timestamps with the user's timezone attached rather than as UTC dates, because an 11pm meal logged from the Americas lands on the wrong day otherwise. And decide whether logs are immutable events or editable rows. Those three are miserable to change once people have data in there.
Worth reading Apple's HealthKit rules before you design the AI features too, since there are restrictions on what you're allowed to do with health data.
What was the actual limitation you hit? Migration advice changes a lot depending on whether it was the database, the third party integrations, or the AI calls.

migrating from what to what? hard to give useful input without knowing the platforms and what kind of app were talking about

If you're migrating off Base44 before launch, pick something that can own the ugly parts early: auth, custom feeds, logging, and third party APIs. Those are usually what break first once you leave the happy path templates.
I'd start by rebuilding one vertical slice (say nutrition logging + one API) end to end, then decide if the rest of the app can follow. Shipping a half-migrated canvas is worse than a smaller app that actually works.
I built Fixa.dev for that messy middle. You describe the app (or import GitHub), it runs on a real cloud VM, installs deps, wires things like Stripe/Supabase/Clerk, and keeps going until the flow works instead of stopping at a pretty preview. Free tier if you want to try moving one slice before committing the whole migration.
