saathi
Saathi gives elderly parents one big button for every dose, in their own language, and gives their children a quiet view of the week from wherever they live.
Tap “I took them” on Amma’s phone and watch Rahul’s phone update. Leave a dose untaken for 30 minutes and he gets an alert.
Set up Amma’s phone, scan the QR code from yours, and the two stay in sync. Doses, reminders and the weekly view are locked with a key that exists only on your two phones. Saathi’s server can’t read any of it.
Indian prescriptions say 1–0–1 for “morning and night”. Saathi uses the same shorthand everywhere: when adding a medicine, in the weekly view, in the summary for the doctor. Nobody has to learn a new schedule format.
The elder view answers one question: what do I take now? The next dose fills the screen, each tablet is drawn the way it looks in the strip, and a single 72-pixel button confirms it. There are no menus to get lost in.
Every line on Amma’s phone is available in English, Hindi and Kannada, and can be read out loud. Text size goes up to 150% without the layout breaking, and the default type is Atkinson Hyperlegible, drawn for low-vision readers.
Rahul’s phone leads with one plain sentence about today. Alerts fire only after a dose is 30 minutes late, and they offer the next useful action: call Amma. Refills show days left, not tablet counts.
Before pairing, Amma sees in her own language exactly what her family will see. Medicine names stay private unless she turns them on. She can pause sharing, stop it, or delete everything from her phone and the server in one step.
The pairing QR code carries a 256-bit key that never leaves the two phones. Saathi’s server only relays sealed data (AES-GCM), and prescriptions are read on the phone itself, so the photo is never uploaded. No accounts, no ads, no trackers, and fonts are served from the app itself.
