What to look for in a seizure diary app: a practical checklist

There are dozens of seizure diary apps available, and choosing between them can feel overwhelming — especially when you're already dealing with a new diagnosis or a change in your seizure pattern. The truth is that most of the features apps advertise don't matter. What matters is whether the app does the basics well enough that you'll actually use it every time you have a seizure.

This checklist covers the features that genuinely make a difference, based on what neurologists look for in seizure records and what people with epilepsy actually need in daily life.

The essentials: features you can't do without

Fast logging

The single most important factor. After a seizure — especially a tonic-clonic — you're exhausted, confused, and possibly injured. If the app requires you to fill in a long form before saving, you won't use it. Look for an app where logging takes under 30 seconds. The minimum you need to capture is seizure type and time. Everything else — duration, triggers, notes — should be optional fields you can fill in later.

Automatic date and time

Never rely on manual entry for timestamps. Your postictal brain cannot accurately recall when a seizure started. An app that auto-fills the current time (with the option to adjust if you're logging retrospectively) removes this source of error. Accurate timing is what reveals nocturnal patterns, morning clusters, and trigger correlations.

Seizure type selection

Different seizure types respond to different treatments. Your app should let you record the type — focal, tonic-clonic, absence, myoclonic, atonic — quickly, ideally from a simple list rather than a free-text field. This makes your data consistently structured and easier for your doctor to analyse.

Export to PDF

Data locked inside an app is only useful to you. At your neurology appointment, you need a printable report that your doctor can read in seconds. For PIP assessments, you need formal documentation of seizure frequency and impact. A good app generates clean, professional PDFs that serve both purposes.

Important but not essential

Shared access for carers

If you have seizures that affect your consciousness or memory, a carer with access to your diary can log episodes you don't remember. This is particularly important for nocturnal seizures and tonic-clonic episodes where you may be unconscious. Not everyone needs this feature, but if you live with someone who witnesses your seizures, it's transformative.

Notes field

A free-text notes field lets you record context that structured fields miss: "was very stressed at work," "missed morning dose," "slept badly," "happened in the bath." Over months, these notes build a picture of your personal trigger profile that you and your neurologist can review together.

Works without downloading from an app store

A web-based app that runs in your browser means no compatibility issues, no storage taken up on your phone, and anyone (including carers) can access it from any device. It also means the developer can update and improve the app without you needing to install anything.

Features to be sceptical about

Medication reminders, mood trackers, weather correlation, wearable device integration, AI-generated insights — these features add complexity without strong evidence that they improve outcomes. They also slow the app down and make the interface busier. A seizure diary's job is to record seizures reliably. If an app tries to be a general health platform, it's likely failing at the one thing that matters most.

The real test

The best way to evaluate a seizure diary app is to ask yourself one question: will I still be using this after my worst seizure? If the answer is no — because it's too complicated, too slow, or requires too much effort — it's not the right app. The best seizure tracker is the one you actually use, consistently, for months and years. Everything else is secondary.
