Tracking how you feel sounds simple until you try to do it every day. Most symptom trackers ask you to open an app, scan a grid of checkboxes, rate a few sliders, and remember to do it consistently. On the days you feel worst, which are exactly the days the data matters most, that is often too much. So the log gets patchy, and a patchy log is hard to trust.
tinh is a symptom tracker built around speaking instead of tapping. You say a sentence about how you feel, the way you would mention it to a friend, and tinh transcribes it and sorts it into structured categories on your device. Logging takes seconds, so it survives the bad days.
To be clear about what tinh is: it is a journaling and tracking tool, not a medical device. It does not diagnose anything, it does not give medical advice, and it is not a substitute for talking to a professional. What it does is help you keep an honest, consistent record that you can review yourself or bring to your own doctor.
Track in Your Own Words
Rigid trackers force your experience into their categories. But "a four out of ten headache" and "dull pressure behind my eyes since I woke up, worse when I look at screens" are not the same note, and the second one is often the useful one. Because tinh starts from natural speech, you can describe what is actually happening instead of picking the closest checkbox.
People use tinh to keep tabs on all kinds of things in plain language: pain and where it is, energy levels through the day, sleep quality, mood, digestion, and side effects after starting something new. You are not limited to a preset list; if you can say it, tinh can log it.
How It Works
Speak a note. Tap, say how you feel, and you are done. No grid, no sliders, no required fields.
tinh organizes it. On-device machine learning reads the transcript and sorts what you said into categories and the custom metrics you care about, so your free-form notes become structured, comparable data.
Patterns surface over time. Because each note is structured, tinh can find statistical relationships across your log, such as a symptom that tends to follow short-sleep nights or certain meals. It surfaces correlations; the meaning is yours to interpret, ideally with a professional. How pattern discovery works covers the detail.
Export when you need to. When you want to bring something to an appointment, you can export your record to share with your doctor. Nothing leaves your device automatically.
Why On-Device Matters for Health Notes
Symptom data is some of the most sensitive information you can record. It can touch on conditions, medications, and details you would not want sitting on a company's servers, subject to breaches, policy changes, or data sharing you never agreed to.
tinh removes that risk by removing the server. Transcription and analysis run on your iPhone or Mac, there is no account, and your log is never uploaded unless you choose to export it. The app works fully offline. For the longer argument, see why an offline journal app matters.
Built for Consistency, Not Streaks
A symptom tracker is only as good as how completely you fill it in. tinh keeps the effort low enough to sustain and does not punish gaps; there are no streak counters to break or guilt notifications. Miss a stretch and you simply pick back up. Low friction is what turns an abandoned tracker into a record worth reading.
