Questions
Is it really free?
Yes. No subscription, no trial, no ads, no account.
Why isn't it in the App Store?
PinLabs installs straight from your browser — tap Add to Home Screen and it opens full-screen like any other app, with notifications. No store, no update prompts: it's always the latest version.
Will reminders work on my iPhone?
Yes, on iOS 16.4 or later once PinLabs is on your Home Screen. Open it from there and turn on reminders when it asks.
Where is my data kept?
On your phone. To send notifications, our server keeps the names and times of your reminders — nothing else. Erase everything from Settings whenever you like.
Does PinLabs tell me what or how much to take?
No. It reminds you of the schedule you enter and keeps your log. It's not medical advice — talk to a clinician about anything you take.
