Yes. Tend is free to download and use, with no ads, subscriptions or in-app purchases.

No. Tend works without an account, login or email address: open the app and start.

Discharge instructions, clinic letters and medication lists from any doctor, for a surgery recovery or a long-term condition. Upload a PDF or a text file, or paste the text in. Add more documents as new doctors weigh in.

Tend can't read scans or photos of pages yet. If a PDF is a scan, Tend will tell you. Type or paste the instructions instead, or ask the care team for a digital copy, often available in the patient portal.

Tend never merges them on its own. When a new document changes a dose you already have, repeats a medication, or says to stop one, the review screen shows both and asks you to replace, add alongside, or skip. It warns you when a dose changes tenfold or more, which is usually a typo. When in doubt, ask the care team.

Everything you enter stays on your phone, protected by Apple's on-device storage and encryption. We have no copy. Full details are in our privacy policy.

AI features read uploaded documents into a care plan for you to review, write the morning briefing and caregiver tips, and check symptom entries against your care team's warning signs. They're optional: turn them off any time in Settings, and the rest of Tend keeps working.

When AI is on, only the text a feature needs is sent to Anthropic's Claude, after names and identifiers are removed. Anthropic doesn't use it to train models. Photos are never sent.

No. It compares an entry with the warning signs your care team wrote down and with the last two weeks of entries, and tells you plainly whether something matched. It never says everything is "normal". If you're worried, contact the care team, or call your local emergency number in an emergency.

Not yet. Symptoms are entered by hand: pain, fatigue, mood, nausea, temperature and notes. If we add Apple Health, it will be optional and stay on your phone.

Not yet. It's the next big feature: everyone who helps will see the same plan, and a dose given on one phone will show as done on everyone's. Accounts will stay optional, and we'll update the privacy policy before it arrives.

Delete any record in the app, or delete the app to remove everything. Because nothing is stored on our servers, that's all it takes.

Not yet. A web app is next, so caregivers in a shared circle can take part without an iPhone, and Android comes after that. If this matters to you, tell us at hello@commongenelabs.com: it helps us prioritize.

Email hello@commongenelabs.com with what happened, a screenshot if you can, your iPhone model and iOS version, and Tend's version (Settings → About). We'll get back to you as quickly as we can.
