Lucerya is a daily companion for people on GLP-1 medications who want to lose fat without losing muscle. Most weight loss includes some muscle. How much depends on what you do about protein, resistance training, and sleep. Lucerya tracks all three alongside your weight, then tells you what the patterns mean in plain language. WHAT LUCERYA DOES Every day, Lucerya reads your logged data and writes a short narrative about what it sees. Not a score. Not a streak. A few sentences about where you are and what to focus on today. Some days the message is encouraging. Some days it tells you something you might not want to hear. It does both calmly. At the end of each week, Lucerya writes a weekly review. The shape of your week in numbers and in words. What worked, what slipped, and what to watch next week. WHAT YOU TRACK Protein. Log whether you hit your protein floor each day. Lucerya calculates your floor based on your body weight and goals. Weight. Step on the scale when you can. Lucerya watches the trend, not the daily number. Resistance training. Log your sessions. Even two days a week changes what happens to your muscle during weight loss. Sleep. Lucerya reads your sleep data from Apple Health. Short sleep and appetite are connected, and Lucerya will notice when that pattern shows up. Symptoms. Nausea, fatigue, constipation, headache. Common on GLP-1 medications, worth tracking, and Lucerya factors them into your daily narrative. HOW IT WORKS Lucerya runs a pattern-recognition engine on your device. Your data never leaves your phone. There is no account, no cloud sync, no server. Everything stays local. The engine evaluates your recent data against a set of rules and selects the most relevant observation for your current situation. The result is a short, specific narrative written for you, not a generic tip. WHAT LUCERYA IS NOT Lucerya is not a medical app. It does not diagnose conditions, prescribe treatments, or replace your physician. It provides general fitness and nutrition insights to help you make informed decisions during your weight loss journey. SUBSCRIPTION Lucerya requires a subscription after a 7-day free trial.

About

Arcline

Features
Read full description

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. Arcline has no accounts, no logins, and no third-party data sharing. Anonymous usage analytics are opt-in. SUBSCRIPTION OPTIONS Arcline is free to try. Premium unlocks unlimited bloodwork panels, trend visualizations, symptom correlation, and PDF export: • Annual — $129/year (best value, includes 7-day free trial) • Monthly — $19.99/month • Lifetime — $149 one-time Terms of use: https://www.arcline.health/terms/ Privacy policy: https://www.arcline.health/privacy/ Subscriptions auto-renew unless canceled at least 24 hours before the end of the current period. Manage or cancel in Settings > Apple ID > Subscriptions. No refunds for partial periods
