What is the best app for IBS?

It depends on what you need: a FODMAP food reference (Monash, FODMAP Friendly, Low FODMAP diet A to Z), a detailed diary (mySymptoms, Bowelle), or an app that reads your diary for you (Ojafi).

Are IBS tracker apps accurate?

They show what tends to come before your symptoms, which is useful for finding foods to test. They cannot diagnose IBS or rule out other causes.

How to choose

Not diagnosed yet: see a GP first. IBS shares symptoms with conditions that need a different answer.
Diagnosed and starting low FODMAP: a FODMAP food list plus a diary, ideally with a dietitian.
You want to see every number: mySymptoms or Bowelle.
You want the app to do the reading: Ojafi.

The NHS recommends keeping a diary of what you eat and any symptoms you get. Any of these apps does that; pick the one you will keep using for three weeks.

Ojafi

Ojafi is our app, so weigh this accordingly. It is a food journal built to be read: you log meals and how they sat, and the iPhone app, in review now, looks for the foods and meal times that keep coming before a bad day, including the foods that turned out fine. It never puts anybody on an elimination diet. The journal works in your browser today, free to start.
