Know exactly what to draw. PepSync turns the numbers on your vial label amount, water, syringe into one clear answer: the units to draw to. Then it keeps the books: what's left in every vial, when each one should be discarded, and the schedule you built for yourself. No spreadsheet. No napkin math. No squinting at tick marks. ALL-NEW IN 2.0 Version 2 is a complete redesign a ground-up UI overhaul built around one idea: the answer comes first. A cleaner dark interface, a streamlined four-tab layout with a quick-add button always under your thumb, and every number you'd act on rendered in crisp monospace. Faster to read at 7 AM, faster to log, easier to trust. THE CALCULATOR - Answer-first: the draw-to units stay pinned while you adjust inputs - Clean-mark check: if your numbers land between syringe marks, PepSync suggests the water amount that fixes it - Show Math: every step of the calculation in plain English — verify anything - Blend support: multi-component vials with per-draw breakdowns - Reverse calc, water calc, unit converter (mcg / mg / mL / IU / units), and titration tools VIALS THAT COUNT THEMSELVES - Log an entry and the vial's remaining count ticks down automatically - Discard countdown runs from your reconstitution date - Projected-empty date tells you in advance whether you'll finish a vial before its discard day - Multiple vials of the same compound? One wears the "in use" badge logging just works - Optional cost tracking per vial SCHEDULES YOU AUTHOR - Build simple daily plans or staged ones — step changes, on/off phases, multiple compounds — entirely from your own entries - "Up next" shows what you scheduled, when, with your rotation site - Missed an entry? It's recorded honestly. Plans never shift and never double up - Optional reminders that respect your privacy: lock-screen text is discreet by default YOURS ALONE - Local-first by architecture: no account, no server, no analytics, no cloud copy - Your data lives in a database on your iPhone — the only way it leaves is you tapping Export - Full backup and restore: one file, readable, yours - Filterable history with CSV export ONE-TIME PURCHASE Pay once, own it. No subscription. Restore anytime on your Apple ID. PepSync is a calculation and record-keeping utility. All compounds, amounts, and schedules are entered by you; the app performs unit math on your numbers and organizes your records. It does not provide dosing recommendations, protocols, or medical advice. For research and educational purposes only. Consult a qualified professional for health decisions.

Every time your kid heads out on their electric ride — e-bike or e-scooter — their phone quietly records it on its own. Minutes after they stop, the whole ride is on your phone: the route on a map, their speed along every street, and the moments worth a conversation pinned right where they happened — over the limit you set, corners taken too hot, phone use mid-ride, rolled stops at the signs you marked. Watch a ride while it's happening, replay it afterward, and send your rider a recap with your notes. No score, no grade to argue about — Rygiene is a recorder, not a referee. Just an honest picture of the ride, and a calmer way to talk about riding better. FOR PARENTS • Every ride mapped, with flagged moments pinned on the route — speeding, hard turns, phone use, rolled stops. • "What went well" — rides highlight the good habits too, not just the flags. • A progress view that shows whether the riding is trending better over time. • You set the speed that matters: alerts use your max for your rider, with the road's own limit for context. • Watch a ride while it's happening, or replay it afterward and send your rider a recap. • Add Places — home, school, a friend's house — and get a heads-up when your rider leaves one. • Mark the stop signs you care about and see whether they actually stopped. • A heads-up if they're riding after dark, or past a curfew time you choose. • A heads-up when the riding phone's battery runs low. • Battery-conscious by design — Rygiene only raises GPS accuracy when it's needed, because a dead phone records nothing. FOR RIDERS • Nothing to remember — rides record automatically. • No score, no grade, no feed to check. They just ride. HOW IT WORKS 1. Create your parent account and add your rider. 2. Set up the rider's phone. 3. They ride. Rygiene records it automatically. 4. You get the ride report — and a heads-up if something needs your attention. PRIVACY FIRST We don't sell your data, show ads, or share your family's information. Collecting a child's data requires verifiable parental consent up front, and you can review or delete it anytime. Rygiene is coaching, not constant tracking. IMPORTANT Rygiene is an informational coaching tool to help you stay informed about how your kid rides. It is not a safety device and does not keep anyone safe or prevent accidents. Very short rides or rides with weak GPS signal may not produce a report. Ride reports, live view, and alerts depend on your rider's phone, battery, and signal, and may be delayed, inaccurate, or missed — treat them as a heads-up, not a safety net. Rygiene is not a substitute for parental supervision, traffic laws, or protective gear, and is not an emergency service. Riding safely is up to your rider. RYGIENE PRO SUBSCRIPTION Rygiene Pro is an auto-renewable subscription: $5.99/month or $49.99/year after the free trial. Payment is charged to your Apple Account at confirmation of purchase, and the subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. Terms of Use: https://rygiene.app/terms Privacy Policy: https://rygiene.app/privacy Keep the freedom. Lose the worry.
