Arcline is the TRT tracking app built for men who take their hormone therapy seriously. If you're on testosterone replacement therapy, the difference between a good protocol and a great one comes down to data. Not more data — better data. Arcline captures the details that actually matter: when your bloodwork was drawn relative to your last injection, which assay method your lab used, how your symptoms track against your protocol over months. It's the tool you wished you had after your first lab panel came back. WHAT ARCLINE DOES • Logs every dose — testosterone, HCG, anastrozole, enclomiphene — with injection site, time, and volume. • Captures full bloodwork panels with trough-vs-peak timing on every draw. Enter 20+ markers: Total T, Free T, SHBG, Estradiol, Hematocrit, PSA, full lipid panel, CMP, and more. • Flags when your hematocrit, hemoglobin, or PSA crosses clinical thresholds — using the same deterministic rules your endocrinologist uses. • Tracks daily symptoms — energy, libido, sleep, mood, morning erections, cognitive clarity, joint comfort — so you can see how your protocol is actually affecting how you feel. • Exports a one-page physician-ready PDF summarizing your last three panels, protocol timeline, and symptom trends. Walk into your appointment prepared. WHY ARCLINE Most TRT trackers treat bloodwork as a single number. Arcline treats it as a measurement in context — the hours since your last injection, the assay method your lab used (sensitive vs. standard estradiol, direct vs. calculated free T), and the protocol version it reflects. That's the context your clinician actually needs to interpret a result. Arcline is also honest about what it isn't. It doesn't give medical advice. It doesn't recommend doses. It doesn't use AI to interpret your labs. Every safety banner, every reference range, every pattern callout uses clinical-grade language — because medical content should read like medical content, not like a fitness app. WHO IT'S FOR • Men on prescribed TRT for at least three months • Patients at clinical TRT practices, urology groups, or endocrinologists • Anyone who's tired of spreadsheets, Notes-app logs, and forgetting what their last estradiol was PRIVACY BY DESIGN Your health data stays on your device and in your private iCloud account.
