Symptom & Habit tracker

Track daily. Export instantly. Keep it private.

You've tried the other apps. Too many questions, too many screens, too expensive subscriptions. Scrambled Brain is different: log what matters in seconds, generate a professional report in one tap, and keep everything stored privately on your device.


No accounts. No cloud. No complexity.


Enjoy all features for free from December 1st to April 1st — no limitations, no subscription needed.

WHAT MAKES US DIFFERENT

Private by design

Your health data lives on your phone. Encrypted, never uploaded. We can't see it, sell it, or lose it in a breach. This isn't a privacy policy. It's how it should be.

Just tracking.
No predictions.

We don't use AI to "analyze" your patterns or predict triggers. Your data, your conclusions, your control.

Simple

One screen. No submenus.

No 21-question onboarding.

Get in, log your day, get out.

That's it.

Flexible

Track symptoms, habits, moods, meals, medications — whatever matters to you. Create unlimited custom trackers. No premium paywall for basic personalization.

Generous

Basic features like unlimited customizations will remain free. Forever. Really.

Humane

We're building this because we need it ourselves. No investors rushing us. No VC playbook. No exit strategy. Just two people trying to make something that actually helps.

FROM CHAOS TO CLARITY

This is what other tracking apps give you

CSV files are technically data...

but they don't look readable when printed.

Especially not from a phone.

FAQ

Ever forget what you were about to say? 
That's a scrambled brain.
We all have one sometimes. Plus, our mascot Ryan (the pink brain) is adorable.

Nope. We started there, but Scrambled Brain works for anyone tracking chronic conditions, mental health, medications, habits, or symptoms. Fibromyalgia, IBS, migraines, Long COVID, anxiety, chronic pain — if you need to remember patterns, this helps.

Everything you track is stored on your device, encrypted. We don't have servers collecting your symptoms or health info. When you generate a PDF, it's created on your phone. You can email it, print it, or share it however you want — but it never passes through us.

Yes! Download it from the App Store (iOS only for now). Android version is coming Q1 2026 — we'll announce when it's ready.

It's called neobrutalism, and it's intentional. Research shows high contrast and bold typography could help people with ADHD to process information faster. Some people love it, some people find it intense. We're adding additional themes in the future so you can customize it.

Two people, husband and wife: River (founder, developer, proud owner of a really scrambled brain who needed this tool himself) and Bogi (co-founder, operations, design support...and honestly, the person keeping River alive while he works 16-hour days). We're bootstrapped, building in public, and weirdly transparent about everything.

Email us at hello@scrambledbrain.app. We actually read every message and seriously consider what users ask for. Not kidding.The Frozen-Stuck log and the dopamine counters were requests by the community.

We will not, but more importantly we couldn't do it even if we tried. Your data is not on our servers. This isn't a promise — it's the architecture. Physically impossible for us to access your tracking data.

Your data is on your device, so the app keeps working. You can still generate PDFs. You just won't get updates. But we're building for the long term — no VC pressure to exit, no hypergrowth playbook. Slow, sustainable, and honest. If you like Scrambled Brain then support us with a Buy-me-a-coffee subscription.

Fair, but you shouldn’t trust anyone blindly anyway. Download it. Use it for free right now. See if it actually helps. If it does, stick around. If not, delete it — no hard feelings. We’re betting on building something genuinely useful, not on tricking you into a subscription you’ll forget about.

The Most Important 9 Weeks of My Life

Just a few months ago, my world got a new name: ADHD. It was a diagnosis that finally explained a lifetime of chaos. I wanted a tool to help me navigate it, but every app I found was a cluttered, overwhelming mess. So, I decided to build my own — a simple, quiet app I called Scrambled Brain.


Then, life presented a non-negotiable deadline.


In the following weeks, I had to navigate a layoff, a family move, and a surgery. But a funny thing happens when your back is against the wall: you don’t have time for distractions. You get focused. You get clear.


So I made a bet on myself. Every night, after my day job, I channeled that focus into building Scrambled Brain.


The RevenueCat Ship-a-ton provided the perfect arena for that fight — a 9-week sprint to turn code into a future. Their tools gave me the power to build a real business, and their deadline gave me the fire.


This wasn’t a story about the obstacles. It was a story about what you can build when you have no other choice but to win.


I built this in public, every step of the way.
