Zelia is your AI health companion — built for people managing a chronic condition, a weight-loss journey, or both at once. No medical degree required. Just clear, sourced answers and a system that remembers your context so you don't have to repeat yourself. MEDICATIONS, MADE SIMPLE • Smart reminders for every dose, with lock screen and widget confirmation • Scan a label, a Webster pack, or an eScript — Zelia reads it for you • Drug and food interaction checking against RxNav and FDA/ACSQHC sources • Refill and repeat tracking so you're never caught out WEIGHT LOSS SUPPORT — BARIATRIC SURGERY & GLP-1 MEDICATIONS • Track weight, body measurements and body composition over time • Log GLP-1 injections (Ozempic, Wegovy, Mounjaro, Zepbound and more) with dose titration history • Bariatric surgery timeline — know exactly what stage of your recovery diet you're in • Dumping syndrome and side-effect logging, matched to your actual recovery stage • Supplement timing checks (calcium, iron, B12 and more) built for post-surgical absorption • Follow your own surgeon's diet plan — scan or paste it in and Zelia follows it, not a generic timeline • Non-scale victories, hydration tracking and progress photos that never leave your device BUILT FOR REAL APPOINTMENTS • AI-generated pre-appointment briefings with your real trends — heart rate, blood pressure, weight, sleep, adherence • Export a clean PDF summary to bring to your doctor, specialist or pharmacist • Save questions and notes as they come to you, review and clear them before your visit ZELIA IS FREE TO USE Track your medications, log symptoms, vitals, weight, GLP-1 injections and hydration, and store your appointments and progress photos — all free, with no time limit. Nothing you log is ever locked away from you. ZELIA PRO — 14-day free trial included Unlocks the full AI health companion: unlimited chat with Zelia, camera scanning for medication labels and eScripts, AI-generated pre-appointment briefings with PDF export, drug/food/supplement interaction checking, advanced health trend charts (HRV, blood pressure, SpO2, AFib), and family/carer sharing. A$8.99/month or A$79.99/year after the trial. DESIGNED TO STAY IN ITS LANE Zelia never diagnoses, never changes your medication or dose, and never replaces your care team. Every piece of clinical information is sourced — TGA, ACSQHC, RxNav, FDA, ASMBS and equivalent regional bodies — and cited so you can check it yourself. If something looks urgent, Zelia tells you to seek care, plainly and immediately. PRIVACY FIRST Your name never leaves your device. Progress photos are stored only in Zelia's private, on-device storage — never your Photos app, never uploaded anywhere. Health data you choose to share with Zelia's AI is used only to answer you, not to build an ad profile. Whether you're managing a heart condition, diabetes, a bariatric recovery, a GLP-1 titration schedule, or all of the above, Zelia adapts to you — not the other way around.
