Ukrainian created an epilepsy tracker for his son that reduced the number of seizures by a third: now it is available for free on the App Store

From parental care to the App Store

Although Oleg Klyapko's career path is connected with the banking sector, programming has remained his passionate hobby since the 90s. Having started coding in Basic and Pascal, he later learned the modern React/Next JS/Node JS stack, and is now mastering Python. This IT experience became indispensable when the need arose to create a medical tool for his son, who struggles with epilepsy.

Anyone who has experienced this illness knows how important it is to record each attack in detail, track potential triggers, and have a clear picture of the disease.

For a long time, Oleg entered all the data about his son’s seizures, his tracking, and influencing factors into a regular Google calendar. However, he later realized that flipping through dozens of entries in the calendar during a doctor’s appointment is inefficient. Precious time is wasted, and the doctor, due to limited timing, may still miss important details. Then Oleg decided to create a specialized tool.

Oleg started developing Seizure Dairy on his own, using AI tools only in consultation mode. But the real breakthrough came when he brought in Claude Code, an AI assistant.

The process of writing code accelerated many times over. By devoting a maximum of 10 hours a week to the project in his free time from his main job, Oleg was able to create, test, and release the first full-fledged release to the App Store in exactly one month.

Seizure Dairy

Seizure Dairy is a seizure diary that helps people with epilepsy and their caregivers track, understand, and manage their condition.

"The main value of the application is a report for the doctor in PDF format. After reviewing it, the doctor can make a decision about adjusting medications, additional diet, etc.," notes Oleg.

• Captures every seizure in seconds: record type, duration, time, triggers, post-contact state, injuries, and video — all from one screen.
• Daily health tracking: Track sleep, stress, medication, and physical activity to identify patterns that trigger attacks.
• Ketogenic diet tracking: enter your daily fat, protein, and carbohydrate intake. The app automatically calculates your keto index and includes your daily nutrient averages in a PDF report for your neurologist.
• PDF and Excel reports for neurologist: generate detailed reports: seizure calendar, time of day distribution, trigger analysis and medication history. Export in PDF or Excel (.xlsx) format.
• Medication management: add medications with dosage and schedule. mark them as taken directly from the tracking screen. get daily reminders when it's time to take your medication.
• History and statistics: view history with filters, calendar, graphs and key indicators - daily average, days without attacks, main triggers.
• Caregiver support: Add caregivers to keep your care team informed.

All data is stored in the users' personal account, and only they have access to it.

The application is available in Ukrainian and English for iOS. You can also check out the development on GitHub .

"About 2 weeks after the start of the application development, I was already running it locally and entering data on my son (including historical data), showing it to the doctor, we had already started to correct a lot of things, and in fact the number of seizures decreased by 30%, which I think is cool," added Oleg.

The role of AI in creating Seizure Dairy: how to be a conductor, not a hostage to technology

For Oleg Klyapko, artificial intelligence has long become not just entertainment, but a basic working tool. Over the past six months, there has been practically no day when he has not used neural networks — both at work and in personal projects.

At work, he uses AI 100%: from preparing presentations and organizing team-building meetings to deep Data Science analysis of customer behavior, modeling product impact triggers, and processing quality survey results (NPS, CSAT).

So when the idea of ​​creating a health tracker for his son came up, bringing in AI was an obvious step. Technically, the process looked like this: Oleg connected the Claude Code terminal assistant to his VS Code development environment, purchased the Pro version ($24 per month), and started coding.

However, the developer emphasizes: AI is not a magic wand that will do everything for you.

"Here you have to be very critical and say "no" to AI more often than agree. Claude Code often proposed wrong solutions or the wrong architecture. In such a process, a person must remain the conductor, otherwise there is a great risk of writing a completely unviable application," Oleg shares his experience.

Based on his successful experience with a one-month release, the developer highlights two key steps for those who want to build products using AI.

"First, you need to understand the goals of vibecoding: what exactly do you want to create to cover some pain (yours or other people's), and whether you are ready to support it constantly, as well as develop in this direction (i.e., whether you get a buzz from the process). Then you should choose a stack and study the base: understand the architecture, the essence of the work and the logic of interaction with a browser or mobile phone, as well as how to support and secure the product. AI will help with this. For example, for mobile development, the React Native + Expo bundle allows you to immediately create applications for iOS and Android, so you don't have to learn Swift or Kotlin separately," the developer advises.

Seizure Dairy Development Plans

The Seizure Dairy application has been in release for over 2 weeks and work on it does not stop for a moment. The developer has already managed to release 5 updates (the current version is 1.1.1), promptly adding new features and fixing bugs. The first testers were Oleg's colleagues at work, whose feedback helped to quickly polish the product. The next important step is to receive expert suggestions and comments from a practicing neurologist, which will make the tracker even more effective from a medical point of view.

In the future, the developer plans to implement two large-scale general functions that will take the application to a new level:

• Adapting the application as a separate interface for caregivers and doctors who can have multiple wards, enter and manage data, as well as implementing an alert button that will allow a person to start recording a seizure and notify their caregivers, which may prevent injury and help record seizures more accurately.

• ML seizure prediction: development of a unique Machine Learning model based on Python that will analyze the patient's historical data and predict the probability of future seizures. Oleg emphasizes: the more high-quality data can be collected, the higher the precision of the neural network's predictions will be.

• Community building: building a safe space within the app where people with epilepsy, their loved ones, and doctors can come together, share experiences, and support each other.

Despite the fact that almost all analogues of Seizure Dairy in the App Store are paid or work on a not cheap subscription, for Oleg this issue is fundamental. The application is and will remain absolutely free.
