Our Take
Symnote is a simple symptom diary for iPhone that lets you track how you feel day-to-day and spot patterns over time. Think of it as a mood journal meets health log—log your headaches, stomach issues, energy crashes, whatever's bugging you, and Symnote shows you the trends. It's the kind of app you don't think you need until you're sitting in a doctor's office trying to remember when the migraines started and how often they're happening.
Tracking symptoms has always been one of those "someone should build this" problems. You could use Notes, but it's messy. You could use a spreadsheet, but that's not exactly user-friendly when you're half-asleep and just want to tap "felt awful today." Symnote strips away the friction—no login walls, no bloated features, just open the app and log. Whether you're managing a chronic condition, prepping for a specialist visit, or just curious about whether your sleep hygiene actually affects your flares, this is the tool that makes it happen.
Built by StanApps, because of course it is.
