19 topics from the guide built into BioHack Track, published in full.
Three ways, all on the Today tab:
Every log updates your streak, deducts from the linked vial, and refreshes the “In Your System” chart.
Logged something by mistake? Right after a quick-log, an Undo toast appears at the bottom. For a completed dose in the list, swipe the row to Undo. To fix details later, go to Today → History, tap the dose, and edit the amount, time, site, notes, or side effects.
If the same compound is due from more than one protocol on the same day, a Check Your Stack card appears above your doses with the real combined total.
Blends are counted by their components. If you run a BPC-157/TB-500 blend and also dose BPC-157 on its own, the card adds the BPC-157 inside the blend to the standalone dose and shows you the true daily figure — something a dose list on its own cannot tell you.
This is arithmetic on the numbers you entered, not medical advice. It never blocks logging, and it is free on every plan.
The Daily Habits card sits above your doses. Tap + to add water a glass at a time — one tap is 8 oz (or 250 mL). Steps are read from Apple Health and shown against your goal; they are never edited here, because Health already owns that number.
Set both goals in Settings → Daily Habits, along with whether water shows in oz or mL. Switching the unit only changes how it is displayed — it never rewrites what you already logged. Clear a goal to hide that row.
Each dose row shows the next site in your rotation (e.g. “L Abdomen”) so you know where before you tap in. Logging a dose automatically advances the rotation. When you log through the confirmation sheet you can also tap a spot on the body map to override it.
Side effects usually show up hours after a dose, not at the syringe — so the app doesn't interrupt you at log time. Instead, each completed dose row has a quiet “How'd it feel?” chip. Tap it whenever a symptom appears to tag it (nausea, injection-site redness, fatigue, etc.) or add your own. You can also add side effects later from Today → History → tap the dose.
Your streak counts consecutive days you've logged your scheduled doses. Finishing the day fires a short confetti celebration and a streak popup. Milestones (7, 30, 100, 365 days) get an extra flourish. Streaks are meant as gentle motivation — missing a day just resets the counter, nothing is lost.
The + button (top-right of Today) is your shortcut hub: Daily Check-In, Log Extra Dose, New Protocol, Log Blood Pressure, Before/After Photos, Add Inventory, Reconstitution Calculator, Export Doctor Report, and Export Financial Report — without switching tabs.
At the top of Today, switch to Calendar to see everything laid out by day, or History to browse everything you've recorded.
History shows all of it, not just doses. Use the filter along the top — All · Doses · Check-Ins · BP · Missed — to narrow it down. Every row opens for editing: tap a dose to change its amount, time, site or side effects; tap a check-in to change any measurement; tap a blood-pressure reading to correct it.
Deleting is per row. Swipe a dose and you'll be asked whether to put it back on the vial. Swipe a blood-pressure row and only that reading goes — the day's weight and measurements stay. Swipe a check-in row and that day's check-in is removed.
Everything you enter can be changed later, from whichever screen you're already on:
Edits take effect everywhere immediately. Correct an old weight and your trends, insights, goal progress and biological age all recalculate on the spot — nothing to refresh.
Two ways in, and they're the same record: the + menu's Log Blood Pressure for a quick reading, or the Blood Pressure fields inside Daily Check-In. Either way it's saved to that day's check-in, shows up in History under the BP filter, and flows into your exports and the Doctor Report.
If you've connected Apple Health, readings are mirrored there too. If that mirror fails — permission not granted, say — your reading is still saved in BioHack Track and the app tells you what happened.
When a schedule is set to Specific Days, you can give each day its own time — e.g. 7 AM on training days and 9 PM on rest days. Open the schedule, choose Specific Days, pick your days, then set a per-day time for any day you want to differ from the default. Days you leave alone just use the schedule's main time, and your reminders follow the per-day times automatically.
Next to your next dose you'll see a drawn U-100 insulin syringe with part of the barrel filled red, and a number like 10 u. That's the app telling you *how far to pull the plunger* — not just what the dose is.
How to read it
• The red fill starts at the needle end and stops exactly at your dose.
• The red line at the edge of the fill is the mark to line the plunger up with.
• The number of units is the same value, written out.
• The tick marks are the real graduations printed on the barrel.
Why units instead of mL? Because that's what's actually printed on an insulin syringe. A U-100 syringe has 100 units per 1 mL, so 10 units = 0.1 mL — but you never have to do that conversion at the vial. Draw to the mark shown.
It only appears when the app can work it out. The draw depends on your reconstitution — how much compound is in the vial and how much bacteriostatic water you added. Set that on the schedule (or on the linked vial) and the syringe appears. No reconstitution on file, or a dose measured in pills/capsules, and you'll just see the dose amount instead.
Where you'll see it: on Today's next dose, on your schedules, in the Reconstitution Calculator, and on the Home Screen widget. On Today only the *next* dose draws the full barrel — the rest show units as plain text, so the screen doesn't become a wall of syringes.
Tap it to zoom. In the app, tapping the syringe opens a large close-up that picks the smallest standard barrel your dose fits (30, 50 or 100 units) so the marks are as far apart as possible for a precise read.
On the widget the syringe is magnified automatically — a small draw is shown against the first 30 or 50 units of the barrel rather than squeezed into the full 100, which makes the fine 2-unit graduations readable. It's always labelled U-100, because it's always the same syringe you're holding — only the zoom changes.
If your vial is measured in IU (HGH, hCG), the same maths applies in IU rather than mg.
Today leads with two dials side by side:
Forgot to log something and it's already the next day? Two ways to fix it:
The Missed list is deliberately quiet about deliberate gaps: days you skipped on purpose, and any stretch while the protocol was paused, are never counted as missed.
Taking a break without deleting anything? Swipe a schedule → Pause (or use the schedule's own Pause control). While paused it stops generating doses and reminders, and the days go grey rather than red — paused days are excluded from your adherence and never show up as missed. Resume picks it straight back up.
Use Pause for a genuine break; use Skip for a single dose you're not taking.
For compounds you step up gradually (a GLP-1, say), turn on cycle phases in the schedule. Give each phase a dose and a length — 0.25 mg for 4 weeks, then 0.5 mg for 4 weeks, and so on — and the app doses you correctly for whichever phase you're in, with no mental arithmetic.
The schedule shows the ramp mapped like a mountain: each phase's dose, its weeks, and the dates, climbing to a clear finish. You'll get a notification at every phase change, including when a break starts.
Open any schedule to see how *that* protocol specifically is going: weight response, body-fat trend, signals worth noticing, and tappable tiles that open the full charts — all scoped to that one compound rather than everything at once.
When a vial tied to an active protocol runs low or empties, a banner appears at the top of Today with a one-tap Restock button (adds a container and refills). Low-stock warnings only fire for compounds you're actively dosing, so a spare vial won't nag you.
The same guide is searchable inside the app under Settings.
