Kangru

Blood types in your pocket

Free · In‑App Purchases

Keep your family's blood types on your device, see who can donate to whom, and share everything with one tap in an emergency. Your data stays on your phone. Blood type info is never around exactly when you need it. Kangru organizes your loved ones' blood types, computes donation compatibility and turns sharing into a single tap — while your data stays on your device. HIGHLIGHTS • Contacts list: Save family and friends with their blood types — your family, your spouse's family and others, organized in one list. • Donation compatibility: Who can donate to you and whom you can donate to — automatic across all 8 ABO/Rh groups. • Emergency mode: Pick the blood type, find a nearby hospital; a help message is ready in seconds. • Emergency alerts: Get notified instantly when someone in your list urgently needs blood. Phone numbers are never sent in the clear — they are irreversibly hashed. • Share lists via QR: Share your list with a QR code; if the recipient approves, people are added to their own list. • Nearby sharing: Exchange blood-type cards with nearby Kangru phones — no internet required. • Widget set: Home screen and lock screen widgets keep your blood type one glance away. • Badges: Unlock levels from Droplet to Kangru Legend as your network grows. • Face ID lock & encrypted backups: Lock the app with Face ID; backups are AES-GCM encrypted. PRIVACY FIRST Kangru has no servers of its own. Blood types and your contact list are stored only on your phone; sharing starts only when you choose. Emergency alerts travel through Apple's iCloud infrastructure. IMPORTANT NOTE Compatibility information in Kangru is based on general ABO/Rh rules and is for informational purposes only; it is not medical advice. Always consult healthcare professionals before any blood donation or transfusion.
