HealthC vs Log Dose

HealthC is a private, on-device tracker for everything you put in your body: prescription medications, hormones, GLP-1 injections, peptides, supplements, vitamins and nootropics. Log a dose in seconds, get reminders so you never miss one, and see how much is still active in your system with clear in-body level charts based on each compound's half-life. Built for people who take their health seriously and want their data to stay theirs. No account. No cloud. No tracking. Everything lives on your iPhone. WHAT YOU CAN DO - Log doses in one tap and never lose track of what you took and when - Smart reminders, a next-dose Home Screen widget and a Lock Screen Live Activity, so your schedule is always a glance away. Log, snooze or skip a dose right from the reminder or the widget without opening the app - In-body level charts that estimate how much of each compound is still active, from published half-life data - Recurring schedules and multi-compound programs with per-compound start dates - Log how you feel (energy, sleep, mood, libido, side effects) and see it right under your level chart, together with sleep, HRV and resting heart rate from Apple Health and your weight trend - Read a lab report by scanning it, taking a photo or opening the PDF: the values are read on your iPhone and converted into the right units - Controls for Control Center, the Lock Screen and the Action button, plus widgets for check-ins and your level - Every blood value shows its phase in your dosing interval, and you can plan the next draw at the same point - Your own check-in questions (like food noise or focus) and "After the dose": how the days after a dose tend to feel - Import from spreadsheets and other apps (CSV), and an automatic backup into a folder you choose - A reconstitution calculator for peptides: powder plus water gives you the exact draw on an insulin syringe - Injection logging with site rotation - Vial and inventory tracking that counts down your supply and reminds you to reorder - Blood-work tracking with reference ranges and trend charts, overlaid on your dose timeline - Body metrics and Apple Health activity (steps, energy, exercise) - A mindfulness breathing timer - A private, on-device place-and-time timeline - Full local backup and CSV export that you control PRIVATE BY DESIGN All of your health data is stored only on your device. HealthC has no servers and no account system; nothing is uploaded, sold or shared. Apple Health data is read on-device and never leaves your phone. Turn on Discreet Mode to hide compound names from your Lock Screen, widget and notifications. IMPORTANT HealthC is a personal tracking tool, not a medical device and not medical advice. The in-body level charts are estimates for personal tracking, not measurements, and must not be used to make dosing decisions. Always consult a qualified healthcare professional, and only track substances that are legally prescribed to you or legally obtained in your jurisdiction.

Track every dose. See what's working. Log Dose is a fast, private tracker for supplements, peptides, GLP-1s and medications: built for people who want to see their health data and their dose history in one place. LOG IN SECONDS • Scan a product barcode to autofill the name and dose • Pick a formulation (tablet, capsule, injection and more) • Quick re-entry: your last dose pre-fills the form • Back-date or pre-log doses with the built-in calendar TAG SIDE EFFECTS • Add symptoms to any dose from quick-tap chips or your own words • Your custom tags are remembered for next time • Review any dose later (time, amount, formulation, effects, notes) SYNC WITH APPLE HEALTH - READ-ONLY • Weight, steps, sleep, resting heart rate, dietary and active energy • Log Dose only reads the categories you approve, and never writes to Health SEE THE PATTERNS • Trends for every metric across 4 weeks to all-time • Dose timeline per medicine - see exactly when you changed dose • Estimated concentration curve based on published half-lives • Compare mode: overlay your body data on your dose history to spot lag • Energy balance: calories in vs out, with your daily deficit or surplus • A monthly activity calendar that fills in as you weigh, log and move PRIVATE BY DEFAULT • Your data is yours: export everything as CSV/JSON at any time • Delete your account and all data in one tap • Optional anonymous cohort comparisons - off by default, and group stats are only ever shown when enough people are in them to prevent identification Log Dose is an informational tracking tool. It is not a medical device and does not provide medical advice, diagnosis or treatment. Estimates such as the concentration curve are for general education only. Always consult a qualified healthcare professional about your medications and doses.
