How it works

You speak

Press record and describe what happened. "She ate yoghurt at breakfast, got hives on her face within 20 minutes."

We organise

Your voice note automatically becomes a structured entry with foods, symptoms, timings, severity and more.

Fully prepared

Generate ladder progress reports to share with your GP or specialist. Print or copy to your messaging app.


Designed for privacy

📱 Stored locally on your device

No cloud sync, no servers. Your child's personal information never leaves your phone unless you choose to export.

🛡️ GDPR compliant

Built for parents who care about data protection. We don't collect more than we need, we can't access what we don't store.

🏥 Easy to share reports

Generate reports that work with your healthcare provider - formatted for specialists who need structured symptom diaries.

🔐 You control your data

Export or delete your records anytime. No lock-in, no subscriptions required to access your own child's health information.


Frequently asked questions

Does this work on Android and iPhone?
Yes. Crumb works on iOS and Android devices, as well as desktop.

Can I share the diary with multiple doctors?
Yes. Copy reports and share via email, print, or show it on your phone during appointments.

What if I forget to log a reaction immediately?
No problem. You can add entries later by voice or manually. The app timestamps based on when the reaction happened, not when you logged it.

How accurate is the voice transcription?
We use high quality speech recognition that understands allergy terminology - so your voice notes are transcribed accurately.

Is this a replacement for seeing a doctor?
No. Crumb helps you document symptoms. It does not offer medical advice and doesn't diagnose allergies.
