Frequently asked
questions.

Scroll to the very bottom of the Add Medications screen — there is an Add Custom Medication option there. You can give it any name, assign your own dosing unit, and it will appear alongside your other medications. This works for vitamins, supplements, peptides, or anything else not in the standard library.

1. Add the medication from the Medications tab.
2. Open the medication detail and tap the Schedule tab.
3. Set a start date and an end date for the first "on" block.
4. For 5-on / 2-off or similar patterns, use a Custom Repeat pattern and configure the active and rest days.

A dedicated tutorial for titration and cycle schedules is being added in an upcoming update.

No — keep logging doses against the same medication entry as before. Your dosing history will remain intact. A dedicated New Bottle flow to reset vial/volume tracking is planned for a future update.

Yes. Create a Group from the Medications tab and drag any medication — including custom-added vitamins and supplements — into it. Groups keep your protocol organised without cluttering the main log view.

The most common cause is an active titration or cycle schedule that is overriding your base dose. Open the medication and go to the Schedule Timeline — from there you can end or adjust the titration schedule, and your new amount will take effect. A confirmation prompt is being added to make this clearer.

Yes — you don't need to duplicate the medication. Open the medication, tap Edit Schedule, then Add Schedule, and set the second time of day. Both doses will then appear in your daily log.

There are two approaches. If the compounds share a single vial, add one custom injectable and use the reconstitution calculator. If they are separate vials drawn together, add each medication and create a Group (Medications → Manage Groups) so they log together as one routine.

You can add it right now as a custom medication (at the bottom of the Add Medications list) with your own name, unit and half-life where relevant. Want it in the built-in library? Email us the compound and we'll add it.

The most common cause is a unit mismatch — your dose is set in one unit (e.g. mcg or IU) while your stock was entered in another (e.g. mg). Open Medications → [medication] → Inventory Tracking → Manage Inventory and make sure the dose unit and the bottle unit match. Once they agree, the doses-left count and run-out date recalculate correctly.

Go to Medications → [medication] → Inventory Tracking → Manage Inventory, then tap an entry to edit it or delete it. To stop tracking stock for a medication entirely, turn off Inventory Tracking in Edit Medication.

Yes. You can enter stock as a number of bottles or vials rather than raw totals, and IU is fully supported as a vial unit (handy for HGH and HCG). If you keep vials of different sizes or concentrations for the same compound, add them as separate entries so each one's size is tracked accurately.

Vials are used First In, First Out — the oldest stock is consumed first. Adding new inventory adds to your total and recomputes the projected run-out date; you can reorder vials with the arrow buttons if needed.

The E2 model currently uses four inputs:

• Testosterone levels (exogenous + endogenous)
• Aromatase inhibitor (AI) use and dose
• Direct exogenous E2
• Your personal baseline from most recent bloodwork

Compounds like Primobolan that indirectly suppress E2 conversion are not yet modeled — the validated pharmacokinetic data needed to do so accurately isn't widely available. If you have references, please share them via support.

Apple Health Records import is now live. OptiPin can pull lab results your provider shares through Apple Health — though what comes through depends on your lab's and provider's coverage.

You can also enter lab values manually any time via the Health Metrics section — testosterone, E2, hematocrit and other markers are all recorded there and used to personalise the forecasting model.

AI-assisted import (e.g. straight from a photo or PDF of your results) is being scoped. Interested? Let us know.

Open Testosterone Estimates, tap the gear icon (top right), and choose Re-calibrate from bloodwork. The "calibrated against" note at the bottom of the graph shows which labs are being used.

One important caveat: the model infers the effect of other compounds from the testosterone-to-E2 ratio in your most recent labs, so the estimate is only accurate while your current stack matches the stack you were on at that blood draw. If you've since added or dropped a compound, the forecast will re-align after your next set of labs.

Swipe-to-log was temporarily removed when medication groups were introduced because the swipe gesture conflicted with expanding and collapsing groups. It is being redesigned and will return in a future update. In the meantime, use a long-press on any medication to get the quick-log menu.

This almost always comes down to the schedule itself. Two things to check:

1. Open the medication, go to the Schedule tab, and confirm the frequency is set to the interval you expect (e.g. "Every 7 days", specific weekdays, or "As Needed" — which won't generate daily prompts).
2. Check whether the medication is on a titration or cycle schedule. An active titration schedule overrides the base schedule and can change which days the dose appears on. Open the Schedule Timeline and end or edit the titration schedule so the days line up with what you expect.

If both look correct but the issue persists, contact support with the medication name and your iOS version.

If you chose GLP-1 as your primary focus during setup, the mood and side-effect trackers are hidden by default. Open the Daily Check-in (Log New Entry), tap Customize, choose Show Hidden, and swipe to show the trackers you want.

Notifications are being revamped so a reminder cancels as soon as you log its dose — including doses logged before the scheduled time. In the meantime, if a reminder or the app-icon badge is stuck, mark the dose "skip for the day" and then unskip it, or simply reopen the app, to clear it.

OptiPin tracks more than 100 injection sites today (104, across the front, back, and an advanced full-body map covering both intramuscular and subcutaneous sites). User-defined custom sites aren't supported yet. Looking for a specific site that isn't there? Let us know and it will be prioritised.

The full body map lives under the Advanced tab on the injection-site picker (it's easy to miss). There you'll find all 104 sites across front, back, intramuscular and subcutaneous. Sites are colour-coded by how recently you used them to help you rotate; automatic rotation isn't built yet.

Not currently — OptiPin uses an annual subscription model. A lifetime purchase option is one of the most frequently requested features and may be offered in the future.

Widgets are on the roadmap. Small and medium widget sizes are planned — showing your next scheduled dose and current estimated hormone levels at a glance, so you can stay on top of your protocol without opening the app.

If you're still inside the free trial you won't be charged, so you can simply let it lapse. To cancel, go to iOS Settings → [your name] → Subscriptions → OptiPin → Cancel Subscription. Refunds are handled by Apple, not by us — request one at reportaproblem.apple.com.

Your data is stored locally on your device and backed up automatically every couple of days — if anything ever looks wrong, restore from Settings → Automatic Backup → Restore. OptiPin doesn't yet sync live across devices; to move to a new device, use a manual backup and restore. Live iCloud sync is being explored.

Yes, though there's no fixed import file format yet. The easiest path is to set up your medications, then use Medications → Track medication usage → Bulk dose logging to enter past doses. If you have a spreadsheet or an export from another app, email it to us and we can help convert it.
