VitalsTrack

Why it exists

I built this so I wouldn't have to keep filling in paper forms and notebooks while tracking health readings for someone close to me. Anyone in the same situation can use it.

Why on-device

Health numbers are personal. VitalsTrack does not talk to a server, does not require a login, and does not send readings anywhere. The database lives on the phone. If the phone is offline, the app still works.

There is no cloud backup unless you make one yourself. Use Export for Doctor (PDF) or Backup in settings to save a copy to a folder on the phone.

What it does

• Log blood sugar in mg/dL or mmol/L, with the time, context (fasting, before/after a meal, bedtime, or random), an optional note, and an optional meal photo
• Log blood pressure in mmHg with systolic and diastolic values, the time, and an optional note
• See your latest blood sugar and blood pressure readings in separate Home cards
• Browse a combined history or filter it by blood sugar or blood pressure
• View separate trend charts for blood sugar and blood pressure
• Set your personal low and high target range for blood sugar
• Log medications and A1C results
• Set a daily reminder so a reading doesn't get skipped
• Save separate blood sugar and blood pressure PDF reports for a selected date range

Support this work

VitalsTrack is the first of several planned apps for health and lifestyle tracking — all offline, all on-device, and built around problems people actually face. No accounts, no cloud, and no subscriptions.

If this project is useful to you, starring the repository on GitHub is a simple way to show support. It also helps make the case for building more tools in the same spirit.
