Find out which foods are gentle on your reflux.

Everything you need to eat with less heartburn
Start with a simple food check. When you're ready, Premium helps you find your own triggers and plan meals around them.
Check any food in seconds
See a food's pH on the color strip, a clear Gentle, Caution or Avoid rating, and gentler swaps from the same food group.
Find the foods that bother you
Log meals and symptoms in a few taps. pHBytes spots patterns — like oatmeal being fine but orange juice not — and you can download your log for your doctor.
Scan, cook and shop with confidence
Scan a barcode to see triggers in packaged foods, and get a 7-day meal plan built around how you eat, the foods you leave out, and your own triggers — with a grocery list sized for your household.
pHBytes started when someone in our family with acid reflux couldn't find a simple way to check which foods were safe to eat. So we built one.

Common questions
Is pHBytes medical advice?
No. pHBytes is an educational and tracking tool. It helps you notice patterns and have better conversations with your doctor, but it doesn't diagnose or treat any condition.
Why does a food's pH matter for reflux?
Acidic foods can irritate an esophagus that's already sore from reflux. Many reflux diets favor foods at pH 5 or higher. pHBytes also warns about triggers that pH alone doesn't show, like fat, caffeine, mint and chocolate.
Do I need an account?
Not to check foods. An account keeps your saved foods and logs safe across devices, and you need one for Premium.
Can I cancel anytime?
Yes. Cancel from your account in two taps. You keep Premium until the end of the period you paid for.
