About
Every tracking method I tried asked more of me than I had,
so I built SymDay.
SymDay came about through my own experiences navigating chronic illness and struggling to track consistently. I know from experience that it can take years to get a diagnosis—a definite answer to, “why do I feel like this?” In the meantime you spend years trying to gain control of what you don’t understand.
One way is to track symptoms, trying to identify triggers and things that make you feel better. I’ve tried many times, but I found the infinite possibilities of factors to keep track of overwhelming and the need to be consistent a burden. Instead of focusing on managing symptoms, I was adding to my plate by having to remember what to track, when, and how. I created SymDay as a way to help those of us who struggle to know what to track and struggle to track consistently.
I thought SymDay could be the app that tracks the data for you, while separating you from the specifics of trying to fit your symptoms into a box. I learned from my own experience with chronic illness that no two people experience symptoms the same way. Not only can they present differently with the same diagnosis but even the perception of pain can vary from person to person. With that in mind, I made sure tracking in SymDay could also be customizable in a way that validates that experience.
Ground Rules
Your data is yours.
Your data will always belong to one person: you. SymDay will not sell or share your symptom data. You can export it or delete it whenever you want.
No AI touches your symptom data.
Your entries are never sent to a model, for analysis, for training, or for anything else. What you log stays between you and your data.
Built for differing abilities.
Accessibility was part of the build from the start, not a pass at the end. SymDay won’t always get it right, and improving it is ongoing work.
No health advice.
SymDay doesn’t tell you how to manage your health. It reflects where you’ve been and where you currently stand in your health journey, and leaves the interpreting to you and your care team.
No automatic renewals.
The dread of forgotten subscriptions isn’t an issue with SymDay.
The Future of SymDay

SymDay is currently in beta. My goal is to learn what’s working and what isn’t with the help of beta users, and I hope to move SymDay into a full release by Spring 2027.
I can’t promise a full release. I can’t support free beta users indefinitely, and paid plans only make sense if there’s enough interest. If there isn’t, SymDay may shut down, and I’ll let users know before it does. If you follow along and want it to continue, let me know!
Improvements I’m planning:
- A habits tracker for self care like sleep, water, etc.
- The ability to group symptoms so you can switch between health focuses.
- A tags menu that lists your existing tags for reuse as you type your notes.
- Import of wearables data.
- A one-time purchase version of SymDay that you install on your own device, so you can store and manage your own data.
