## What is Tadoo?

Tadoo Health is built for testosterone replacement therapy. Bloodwork tells you about one morning; Tadoo estimates your levels for every day in between, calibrated to your own labs, next to the injections you log. It also tracks peptides, daily medications, and supplements.

ESTIMATED LEVELS BETWEEN LABS
Enter your lab results and Trends shows hormone estimates for the days between draws, calibrated to your own bloodwork, alongside your dose history and how you felt. See your peak, trough, and swing across each injection cycle, and how your routine and your numbers move together.

LOG IN ONE TAP
Every medication gets a card on your Home screen. Tap the circle and the dose is recorded with the time, the amount you configured, and, for injections, the next site in your rotation.

BUILT FOR INJECTIONS
Vial-based setup: enter your vial strength and how much you mixed it with, then dose in mg, mcg, IU, or mL. The app converts exactly and shows every equivalent. A body map tracks injection sites and suggests where to go next.

NEVER MISS A DOSE
Reminders per medication and per time of day, weekly or every-N-days schedules, and skip a day when you need to. Log or skip a dose right from the reminder.

MORE
• Apple Health sync for sleep, heart rate, activity, and more, free for everyone
• Bo, a built-in assistant that answers questions about your own log
• Doctor report: a clean PDF of your doses and labs for your next appointment
• Multiple profiles on one device
• Local export, plus encrypted backup on Tadoo's servers

PRO
The free tier covers daily logging, reminders, and Apple Health sync. Tadoo Health Pro adds the full Trends suite, insights, the doctor report, encrypted backup on Tadoo's servers, multiple profiles, the supply tracker, and expanded assistant use. New subscribers get the first month free. After that, Pro is a monthly or yearly subscription, billed through your Apple ID and cancellable any time in your App Store subscriptions. No account is needed to subscribe.

IMPORTANT
Tadoo Health is a personal record-keeping tool. It does not provide medical advice, dosing instructions, or treatment recommendations, and it is not a substitute for your doctor. All doses and schedules are entered by you from your own prescription, product label, or clinician's instructions. Hormone estimates are models, not lab results.

Privacy: your data lives on your device. Backup is end-to-end encrypted on Tadoo's servers. We never sell or share your health information.
