HackitRx 2026 solution concept
The build, in plain words
The solution files
Bleedwise is a bleed record for people with haemophilia. It holds the plan your centre gave you, takes you through a bleed one step at a time, and tracks it to recovery. It has no AI and does no dose maths. Live at bleedwise.org.
How it works
Your centre's plan, at the bleed
1. Set up once.
Type, severity, product, the dose your centre wrote, the centre's number, your kit and stock. A caregiver can set it up for someone else.
2. Log a bleed.
Tap where it is on the body map and answer a few questions. You get one next step: treat at home, dose then go to A&E, or call 995.
3. Follow it to recovery.
Each bleed gets a page with check-ins at 24 hours, day 2, day 3, the physio point and two weeks, until you close it.
- Patient
- Adults on prophylaxis or on demand.
- Caregiver
- Logs for someone else in the same app.
- Care team
- Desktop view: a queue of shared bleeds, pattern flags, one prompt back.
- Product team
- A dashboard showing where people drop off.
The gap it answers
Familiar bleeds are handled. The hard ones are a new site, an odd symptom, or a Sunday night with the clinic closed.
That is when people fall back on memory, a group chat or a search engine. Bleedwise puts their own centre's plan in front of them instead, with sources on every card, and shows whether the centre's line is open right now.
See it working.
Open it on a phone. Set up, then log a bleed.
Sharing with a care team is demo only. Nothing logged reaches a hospital yet.
Open BleedwiseThe rules the app cannot break
You type in the dose your centre wrote and the app shows it back: "Your dose, as your centre wrote it". The only sum it does is how many vials make up that dose.
The symptom checker counts what you ticked, for example "3 of 5 signs of a joint bleed", then asks "Think it is a bleed?". You make the call.
Logging a bleed and checking a symptom both open on "Any of these? Call 995 now." Tap one and the next screen is Call 995.
Joint, muscle, bruise, mouth, nose, cut, urine: treat it at home now. Head, eye, abdomen and gut, iliopsoas: give your dose, then go to A&E. Neck or throat: call 995.
After the card the app asks "What are you doing now?": home, A&E or 995. Pick something else and it shows what the card suggested, then saves both.
"Your nurse decides that, not this app." It tells you whether the line is open now or when it next opens. A check-in that lands on a weekend says go to A&E if it is getting worse, not wait for Monday.
The emergency signs, the symptom checker, each bleed card and the end of every library deck list the published guidance behind them, mostly the WFH guidelines.
Nothing in the app calls a model. The cards and the next step are fixed content, so the same answers always give the same result.
You choose, as a default or bleed by bleed. A shared bleed waits in the care team's queue until they open it. Today that queue is demo only, and the app says so wherever it offers sharing.
The app saves both the step it advised and the step the patient took, so a centre can later count how often people went further than advised and how often they held back.
What is built, and what is not
Built
Setup and the card. Bleed logging with body map, red flags and three lanes. The bleed page with check-ins and closing. Dose logging with stock and adherence. The symptom checker and library. Care team notes, signed by a clinician. My record with CSV export. Works offline. Developer dashboard.
Built, demo only
Sharing a bleed with the care team, and the care team queue, roster, patient and centre views. The app tells patients nothing reaches a hospital yet.
Not built yet
Clinician sign-off on library cards. Push reminders. Spreadsheet import. Physio booking: the app prompts, the centre books.
Will not build
Dose calculation. A second dose on the app's say-so. AI in the decision path. A helpline. Chinese, Malay and Tamil come after English.
