Daruj kri
A blood donation companion for Slovenia: live national blood stock for your group and all the others, donation drives and transfusion centres near you, and a private donation log that tells you when you can donate again. Every donation counts.
Drag through the app
From stock levels to your next donation
Daruj kri shows the public data of Slovenia's transfusion institute and pairs it with your own private donation log. Everything you enter stays on your device, and the app never sends anything about you anywhere.
Live national blood stock
Stock levels for all eight blood groups, straight from the public ZTM data. Your own group gets a hero card with an animated gauge; the rest line up in a bar chart colour-graded by level.
The compatibility wheel
An interactive donor wheel shows who you can give to and who you can receive from. Turn it around and check any group at a glance.
Drives and centres near you
Live field donation drives from the ZTM data plus all 11 permanent transfusion centres in one list, with phone numbers you can tap to call.
Search and favourites
Search works with or without Slovenian diacritics, so any spelling finds the place. Star the locations you visit and they sort to the top.
A private donation log
Every donation in one place, with optional hemoglobin values and a hand-drawn trend chart. The log lives only on your device.
The eligibility countdown
An eligibility card counts down to the day you can donate again: 3 months for men, 4 for women. No maths, no guessing.
An optional reminder
A local notification at 09:00 on the day, a day before or a week before your next eligible date. No push servers; everything is generated on your phone.
Profile and guidance
Your gender and blood group personalize the whole app, and the Info tab covers who can donate and what to do before and after donating.
Built natively for iPhone and iPad
The iOS build is Swift and SwiftUI, not a wrapper, with the same stock, locations, log and reminders as Android. One extra: onboarding can prefill your blood type and biological sex from Apple Health with a single optional, read-only request; the values are stored only in the local profile. Available now on the App Store.
Data and privacy
Daruj kri reads two public ZTM endpoints over HTTPS: the national blood stock levels and the list of field donation drives. The requests carry no account, identifier or personal data. Your profile, donation history and reminder settings stay on your device. Daruj kri is an independent app, not an official ZTM product; it simply presents the same public data.
