Biohack Tracker is a private log for the protocols, supplements and medications you already use. Set reminders on the days you choose, tick each one off in a tap, and keep a site-rotation log for prescribed injectables. Import your blood tests to see every marker against its reference range over time, and sync sleep, HRV, resting heart rate and workouts from Apple Health. Biohack Tracker is a tracking and education tool. It is not a medical device and does not sell, source, recommend or dose any substance. WHAT YOU CAN DO • Today: what's due, what's done and your Biohack score at a glance, with one-tap "Mark taken". • Protocol log: log protocols, supplements and medications by route with colour-coded icons, set reminders on the days you choose and see your adherence. • Site rotation: numbered body sites with rest rings that show how recently each was used, plus a general rotation guide to use alongside your prescriber's or pharmacist's instructions. • Blood tests: import a PDF or photo. Each marker is shown against its reference range and trended, with "worth discussing with your GP" patterns and retest reminders. • Sleep, recovery and training: sleep stages, HRV, resting heart rate, breathing rate, blood oxygen and temperature from Apple Watch, Oura, Whoop, Garmin and more, plus workouts (including sessions synced from Strava or Runna) and your Runna plan. • Scores: a Vitality score from your labs and a Wellbeing score from your last 7 days combine into one Biohack score, with ways to improve. A guide to your own trends, not a medical assessment. • Templates and library: educational routine templates (no doses) and a reference library of 215 supplements and compounds with evidence levels, safety flags and legal status. • Biohack coach (Pro): ask about your own data. The coach can build a simple 4-week habit plan from a result, show the before and after when you retest, answer questions about a photo of a meal or label, and remembers what you tell it (see or clear it any time). General guidance only, never dosing or diagnosis. AI features run only after you allow them. • Clinician-ready reports, progress photos and metabolic health. PRIVACY Your data is stored in your private account and encrypted in transit and at rest. We never sell your data or use it for advertising, and your health data is never used to train AI models. Apple Health data is read-only. Download all your data or delete your account at any time. LIFETIME UNLOCK & PRO Free to download. A single one-time purchase (A$4.99, no subscription) unlocks all tracking: protocols and reminders, site rotation, sleep and recovery sync, templates, blood test import, charts, progress photos, metabolic health and retest reminders. Pro adds the AI layer and includes the unlock: the Biohack coach, 4-week plans, blood test and protocol analysis, trend projections, clinician-ready PDF export and the weekly digest. Pro is A$7.99/month or A$79.99/year. After the unlock you can ask the coach 5 questions and run 1 blood test analysis free. Fair-use limits apply to AI features. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless cancelled at least 24 hours before the period ends; manage or cancel in your device Settings. IMPORTANT Biohack Tracker is for educational and organisational support only. It is not a medical device, does not diagnose, treat, cure or prevent any disease, does not prescribe or recommend doses, and is not a substitute for professional medical advice. Wearable readings are device estimates. Always check with your doctor before making health decisions. In a medical emergency, call your local emergency number.

Verdict
The clearest difference is ads: Biohack at none against 75 Hard's shown. Biohack also leads on update cadence (every 2 days vs every 8 days). 75 Hard's advantage is device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.
