Often asked "which GLP-1 app ?" — and what I actually tell people

By: Ruby Marusic, APD

I get this question in almost every consult now: "I downloaded [an app] to track my Ozempic/Zepbound — is it any good, and is there something better for the food side of things?"

The short version: most of the popular GLP-1 apps are genuinely good at the logging side — doses, weight, side-effect timing. Very few of them help with the question that actually determines whether your week goes smoothly: what do I cook that I can tolerate, that also feeds the rest of my household, without a separate grocery trip just for me?

What the current crop of apps actually does well

If you've looked around, you've probably seen a few names come up a lot:

None of that is a knock on these apps — they solve a real problem, and if dose-and-symptom logging is what you need, several of them do it well.

The gap I actually see in practice

What I don't see any of them do is connect how you're feeling to what to actually put on the plate — and then help that scale to a whole household, not just one plate.

A symptom log tells you that today is a rough nausea day. It doesn't tell you what to cook for dinner tonight that's less likely to set it off, or how to adjust that same meal so it still works for a partner or kids who aren't on the medication and don't need a smaller, gentler portion.

That's the specific gap Food Signals is built around: every recipe is scored against five common GLP-1 side effects — nausea, bloating, constipation, fatigue, and low appetite — so when you're having a rough day, you can filter straight to meals that are more likely to sit well, rather than guessing. And because most people on these medications are still cooking for a household, not just themselves, the meal plan can scale up the same recipe to feed everyone else at the table, then turn the week into a shopping list automatically.

The bit I do want to flag: medication sales and your data

This one matters clinically, not just practically. A few apps in this space — MeAgain is one — sell compounded semaglutide or tirzepatide directly through the app to the same people logging their symptoms in it. I'd rather my patients know that going in: if an app's business model includes selling you medication, it has a financial interest in that conversation, on top of the tracking one.

Food Signals doesn't sell medication, and doesn't sell or share your health data for any commercial purpose — full stop. That's not a unique claim in this category (a couple of the dedicated trackers take the same stance), but it's worth checking for any app you're using, because not all of them do.

What I'd actually suggest

Meds are one tool in the plan — they work best alongside steady meal patterns, movement, sleep, and someone keeping an eye on the clinical side. If you want detailed dose and pharmacology tracking, a dedicated tracker can genuinely complement what we do. If the harder part of your week is "what do I actually cook, for myself and my family, on a day when my stomach isn't cooperating" — that's the part I built Food Signals to solve.

If you'd like to see how that works for a whole household, here is the family meal plan.

If you're curious, the fastest way to see the difference is to pull up a recipe scored against whichever symptom is giving you trouble this week, and see what it recommends.
