Allergen tracker app
Catches what you can't eat.
Reps is a food allergy alert app built into a full nutrition tracker. Set your allergies once, and every meal you log gets checked against them — so you see the warning before you eat, not after.

An allergy check on every meal you log
Most food trackers count calories. Reps also watches what you're allergic to.
You tell Reps your allergens once — the app keeps a dietary profile you control. From then on, every meal you log is scanned against that profile automatically. Log a plate by snapping a photo, saying it out loud, or typing it, and Reps identifies the ingredients and cross-checks them the moment the meal is recorded. If something matches, you get an alert before it becomes a problem.
The alert is severity-graded, so a trace-risk ingredient reads differently from an obvious one — you see the matched ingredient called out, not a vague warning. It's the difference between a food diary and a food diary that's actually looking out for you.
Set it once
Build a dietary profile with the allergens you need to avoid. Reps remembers it for every future meal — no re-entering, no toggling per log.
Checked instantly
Every logged meal is scanned against your profile as it's saved, so the warning lands before you eat rather than after.
Ingredient-level alerts
Matches are graded by severity and the specific ingredient is highlighted — you see exactly what tripped the flag.
Log any way
Photo, voice, or text. However you record a meal, the allergen check runs the same way.
Not just a warning — a whole nutrition picture
The allergen check rides on top of Reps' full meal logging. The same photo that gets scanned for allergens also gives you calories and macros — protein, carbs, and fat — plus water tracking, so eating around an allergy doesn't mean giving up on your goals. And because Reps also reads your Apple Watch recovery and training, the AI coach, Rex, can reason about your nutrition in the context of how you're actually training.
Reps is a tracking aid, not a medical device, and doesn't replace reading ingredient labels or professional medical advice for serious allergies.
Common questions
How does Reps check my meals for allergens?
You set your allergens once in your dietary profile. Every time you log a meal — by photo, voice, or text — Reps scans the identified ingredients against that profile and raises a severity-graded alert on anything that matches, so you see the warning before you eat.
Is Reps a medical device or a substitute for reading labels?
No. Reps is a tracking aid, not a medical device. It helps you catch likely allergens in meals you log, but you should always read ingredient labels and follow your doctor's guidance for serious allergies.
Can I track more than one allergy?
Yes. You can add multiple allergens to your profile, and every logged meal is checked against all of them at once.
What do I need to use Reps?
An iPhone. An Apple Watch Series 6 or later unlocks the recovery and readiness features, but meal logging and allergen alerts work from the iPhone.
