✨ What is Dosely?

Dosely helps people on GLP-1 medications (semaglutide, tirzepatide, dulaglutide, liraglutide, CagriSema) stay on track with everything that matters — and nothing that doesn't:

💉 Injection tracking & 6-site rotation	Log doses in seconds — medication, mg, injection site, notes. 6-site visual rotation prevents tissue fatigue and soreness.
📈 Medication levels & decay curves	Smooth cubic Bézier pharmacokinetic curves model estimated circulating levels and 7-day half-life elimination.
💧 Daily care: water & protein	1-tap quick logging for hydration (+250 mL / +500 mL) and protein (+20 g / +30 g) to combat GI side effects.
⌚ Wear OS smartwatch companion	Standalone wrist app with rotary input, 1-tap shot confirmation, quick hydration logging, and weight steppers.
💎 Dosely+ ad-free ($0.99 / mo)	Optional auto-renewing Google Play subscription to remove all banner ads while keeping data 100% private.
🖊️ Pen stock & re-up alerts	A pen is deducted per injection. Low-stock and out-of-stock warnings arrive before you run dry.
⚖️ Weight journey	Start weight, goal, total change, 7-day average, trend chart — in kg or lb with Health Connect support.
📅 Calendar & insights	Month view of doses, skips and weigh-ins. Streaks, adherence, projected goal date.
🤖 On-device AI coach	Google's Gemma model runs fully offline on your phone. Ask about nausea, nutrition, titration, habits.
🌍 59 languages	The entire app translates on device via Google ML Kit. No server round-trips.
🔔 Reminders	Dose reminders, refill nudges, weekly weigh-in prompts.
📱 Home-screen widget	Next dose, pen stock and latest weight at a glance.
🌗 Beautiful & dark	Light and dark themes, smooth animated transitions.

🔒 Privacy-first, by design

• All health data stays on your phone — injections, weights, notes and AI chats live in local storage. There is no account, no cloud sync, no analytics SDK.
• The AI coach is offline. The Gemma model sits in your app's private storage and runs on your device's CPU. Your questions never leave your phone.
• No ads inside your health data. The optional ad banner (which keeps Dosely free) is governed by Google's consent flow, and you can review choices anytime via in-app Privacy options. Details in the Privacy Policy.
• Read the Terms of Service.

Medical disclaimer: Dosely is a tracking tool, not a medical device. It does not provide medical advice, diagnosis or treatment. The AI coach can make mistakes — always consult a qualified healthcare professional about your medication and health.
