Why Logify

More than counting calories.

  • Spot what doesn't agree with you

    Log symptoms like bloating or heartburn and link them to a meal. Logify shows you which dishes keep causing trouble.

  • No subscription

    Buy once, use it for good. No trial that turns into a yearly plan, no features behind a paywall.

  • Your data stays yours

    No account, no servers of ours. Your entries live on your iPhone and in your private iCloud – we never see them.

Food tolerance

Your gut keeps a diary.

Most nutrition apps only count calories. Logify also remembers how you felt after eating – and finds the patterns you miss in everyday life.

  1. Rate the meal

    After eating, tap a face: good, so-so or bad.

  2. Log a symptom

    Pick from nine symptoms – from bloating and heartburn to fatigue – and link them to the meals of the last 24 hours.

  3. See the pattern

    The "Possible Intolerances" statistic shows how often a meal leads to symptoms, e.g. "Latte macchiato: 6 of 12 times, mostly bloating".

  • Bloating
  • Stomach ache
  • Heartburn
  • Diarrhea
  • Nausea
  • Feeling of fullness
  • Headache
  • Fatigue
  • Skin

Logify helps you spot patterns and does not make a diagnosis. If symptoms persist, please talk to your doctor.
