Beanie is a mint-green, bean-shaped friend. The app doesn't lecture. It stays beside the patient while they become the teacher of their own body.
Moments that repeat in patients' lives. Each one became a feature.
"The checkup report said eGFR 54. Nothing hurt."
The kidneys stay quiet until late stage 3. There is a number but no language for it, so most people simply walk past it.
"A three-minute visit. I didn't get to ask a single thing."
Three months of life have to fit into a few minutes. The patient, unable to recall them, says "I've been fine." The doctor sees numbers; the patient lived a life; the two never meet.
"Thirty minutes of searching. All that was left was fear."
Generic information ends at "eat this, don't eat that." Nothing starts from my numbers and my table.
"Ask, and it's nagging. Don't ask, and it's worry."
The person cooking and the person logging are different people, looking at different information — so care turns into surveillance.
SLOW · SILENT · EXPENSIVE — where all three overlap
It progresses slowly, shows no symptoms, and costs dearly when caught late. A disease with all three needs a tool that records daily, organizes before the visit, and is seen together.
The base screens are the same for anyone worried about their kidneys; only the dialysis log is an add-on.
Ninety days of labs, blood pressure, weight, body signals, and questions on one page. Print it or save as PDF and bring it along. The patient holds the report — the app never sends it to clinicians.
Last labs beside this one, last 30 days beside these 30. In a chronic condition, holding steady must be shown as an achievement.
A single line at a time. No nagging on skipped days. It speaks only before a visit, in a high-blood-pressure week, or when swelling persists.
The patient picks which items to show (eGFR, blood pressure, weight, body signals, meal patterns, questions) and sends one link. Unchecked items are not in the link at all. Family opens it read-only in the same app. Live sync comes once a server exists.
Breakfast, lunch, dinner and snack — one line and a photo each, pattern chips, and potassium / phosphorus / sodium caution tags. You set the daily count goal; the app only counts. The next step, Reverse Content (swap suggestions that start from what you ate), is v2.
Only for those on dialysis. Pre/post weight per session and the gain between sessions, dry weight, cups of fluid, symptoms and access-site signals, medication check. Off, it appears nowhere in the app. Read more →

Rows are the three needs of Self-Determination Theory; columns are the product's five systems. Ego-depletion theory overlaps: management fails not from weak will but from too many daily decisions. Good design removes decisions rather than adding features.

| 05 Family & Community | Choose what to show later | Anonymous peers, same stage later | Learn from those ahead later |
Two cells come from system 02 because the pre-visit report is the most defensible feature. CKD Tracker and KidneyPal already advertise "a PDF for your doctor"; lose here and everything is lost.
Most early churn comes from the feeling that "this app bosses me around." Competence takes time to build; autonomy is decided on the first screen.
Time-in-app and log counts prove the app is well made — not that the patient is better off.
No language for one's own state.
Facts recovered. Phase 1 goal for most users.
Language acquired. Phase 2 goal. Pass/fail line for each R&D cycle.
Life linked to numbers. Phase 3 goal. This is where the visit changes.
Few reach it, but those few pull the next patient up.
Korea's MFDS judges by intended use and risk, and the deciding factor is the wording. The same feature is wellness if it "helps you record" and a medical device if it "slows progression." In the U.S., the FDA explicitly lists tools that let patients record and organize health information as not medical devices.
| What we don't do | What we do instead |
|---|---|
| Stage the disease from eGFR and raise risk alarms | Let the patient enter, store, and chart the numbers the hospital gave them. eGFR is shown as a reference value only |
| Tell an individual "cut protein to X grams" | General dietary information from authoritative bodies, plus reminders. Individual guidance only within a clinician's prescription or referral |
| Transmit or analyze patient data for clinicians | The patient prints their own report and carries it in |
| Use "diagnose · treat · slow · improve" in marketing | Consistent health-management language: record, organize, look together |
