Built for peptide, TRT, and GLP-1 protocols. Set up your vial in seconds, log every dose, and see your modeled levels between doses. Skip the spreadsheet and the back-of-envelope math: enter your vial size and water volume to get the concentration and the syringe units to draw. YOUR DATA IS YOURS No account, no sign-up. Your protocol stays on your device and syncs only through your own private iCloud, and your Ask PinPoint history is kept on the device and never synced. Nothing is sent until you tap Allow. When you ask a question, your message, your recent messages, and the relevant tracker context are sent, and PinPoint doesn't store any of it on its servers. ASK PINPOINT (PRO) - An in-app assistant for questions about your own protocol and the compound library - Ask what's on your schedule, what you logged last month, or what published references say about a compound - Educational reference with sources. It never recommends a dose or a protocol change. - Consent first: nothing is sent until you tap Allow DOSE TRACKING & SCHEDULING (PRO) - Log injections with compound, dose, site, and pain level - Titration phases: plan step-ups and step-downs, and the schedule follows them - Backfill past doses so your history is complete from day one - Site rotation suggests where to inject next - Daily, every other day, 3.5-day, weekly, every two weeks, or custom - Reminders tied to the day and time you set, and a color-coded calendar VIAL SETUP & UNIT CONVERSION (PRO) - Enter vial size in mg, mcg, or IU and water volume for instant concentration and syringe units - Visual fill-line guide for 0.3, 0.5, and 1.0 mL insulin syringes YOUR LEVELS BETWEEN DOSES (PRO) - The Home curve models your levels between doses from published half-life data - Drag to scrub modeled values at any timestamp, or preview 30 days of a dose pattern VIALS & PENS (PRO) - Track vials and prefilled pens side by side - A supply forecast estimates when your stock runs out, so you reorder in time ONE LIBRARY: PEPTIDES, TRT, GLP-1 - BPC-157, TB-500, Ipamorelin, CJC-1295, GHK-Cu, PT-141, and more - Testosterone Cypionate, Enanthate, and Undecanoate - Semaglutide, Tirzepatide, Liraglutide, Retatrutide - Longevity and ancillaries: NAD+, Glutathione, Epitalon, HCG, Anastrozole - Injection, oral, nasal, topical, and sublingual routes - Half-life and absorption data from FDA prescribing labels and peer-reviewed literature, cited in-app ALSO IN PRO - Weight, calories, protein, and water, with trend charts - Side effects with severity ratings, plus daily notes - Apple Health sync for weight, water, nutrition, and activity - Home Screen quick actions and Siri dose logging - Next-dose countdown gauges and Home Screen widgets - Accent themes, PDF/CSV/JSON export, and iCloud sync NOW IN 11 LANGUAGES English, German, Spanish, French, Italian, Japanese, Korean, Polish, Portuguese, and Chinese (Simplified and Traditional).
