A log for blood, plasma and platelet donations. It works out the earliest date you could give again, flags the trips a clinic will ask about, and reminds you when it is time to book.

The next date, per type of donation

Whole blood, plasma and platelets do not wait the same length of time. Héma-Québec’s intervals are built in and were checked against their site on 20 September 2026. Other organisations — Canadian Blood Services, the American Red Cross, EFS, NHSBT — ship with starting values the app marks as unverified, and you can change them.

The trips that count

Malaria, Zika, Chagas: where you have been changes when you can give. Dono Log reads the places you already recorded in Tessella, works out which stays matter, and prints a sheet you can hand to the nurse.

It asks instead of guessing

Some rules turn on a city rather than a country. When what it knows is not enough to decide — Peru without a city, say — it asks you rather than assuming the answer.

Never a verdict

The app counts days and points at rules. It does not tell you that you are eligible: that decision belongs to the clinic that sees you. The widgets show your number of donations, deliberately, and never a ruling.

Your donor card, ready at the counter

Photograph it once. The number, the blood group and the barcode are read on the device, shown full screen when you arrive, added to Wallet, and mirrored on the Watch.

Appointments that actually remind you

Add one to your calendar — write-only: Dono Log never reads your calendar — and get a reminder the evening before and two hours ahead.

On your wrist and your lock screen

Home screen and lock screen widgets, a Control Centre button, an Apple Watch app with a “donated today” button, and complications for four watch face shapes.

Yours to take with you

Export everything as CSV or JSON, whenever you want, without asking us.

No server of ours

No account, no ads, no tracking. Your donations live on the iPhone and, if you want, in your own private iCloud. Dono Log is an independent app: it is not affiliated with Héma-Québec or with any blood service, and it does not connect to their systems.

English, French, Spanish, Italian and Japanese. Paid once, $4.99, with no in-app purchase and nothing held back.

Dono Log is at version 0.1 and is being finished. There is nothing to download yet — this page will carry the link when there is.
