Draft: not yet reviewed by a clinician

Use this page to prepare questions for your care team. It does not replace their advice. Your own targets and doses come from your nephrologist, diabetes team and renal dietitian.

First setup

Setup takes about ten minutes: sign in, fill in your profile, then copy in your care team's targets or ask the app for starting ones. Have your latest lab report and your dialysis schedule (if you have one) next to you.

Starting points, not your prescription

These numbers are typical starting points from guidelines. Your nephrologist, diabetes team and renal dietitian set your own numbers from your blood tests, urine output and medicines, and change them as your labs change. If your lab report or your team says something different, they win.

1. Sign in

Every person has their own account, with their own log, profile, targets and keys (design note 07):

  1. Your admin sends you a link: an invite link, or a setup link for an account the admin already made for you (the page then shows your user name). Each link works once and expires, after 7 days unless your admin chose another time.
  2. Open it on the device you will use most, and choose a user name (for an invite) and a password.
  3. The password must be at least 15 characters (unless your admin chose another minimum). Long is what makes it strong: a short sentence such as blue kettle on a sunny porch is fine, and you do not need symbols or capitals (NIST SP 800-63B-4, section 3.1.1.2). The app refuses very common passwords, your user name or name, and runs such as aaaa… or 12345…. A password manager and pasting are allowed.
  4. You stay signed in for up to 30 days, or 14 days if you do not open the app. Settings → Account lists the devices you are signed in on, and signs out any of them.
  5. On a shared computer, sign out when you finish (Settings → Account → Sign out).

Some changes, such as a new password, exporting your data or adding a key, ask for your password again if you have not typed it in the last 10 minutes. If you forget your password, ask the admin for a reset link; there is no email reset. If your admin set up sign-in through another service (for example Authelia or Tailscale), you sign in there instead and never set a password in the app.

The person who installs the server creates the first account, the admin, with a one-time setup code from the server's log (Self-hosting).

2. Fill in your profile

Open Profile and enter:

Field What to enter Tip
Weight (kg) Your weight today. On dialysis, your dry (target) weight after a session pounds ÷ 2.2 = kg: 154 lb = 70 kg
Height (cm) Your height inches × 2.54 = cm: 5 ft 7 in = 67 in = 170 cm
CKD stage 1, 2, 3a, 3b, 4 or 5, from your nephrologist after a transplant, the stage of the new kidney. A new account shows Not chosen yet; until you pick, the app uses stage 3b
Dialysis None, Hemodialysis or Peritoneal
Dialysis days The weekdays of your hemodialysis sessions lets the app total potassium, sodium and fluid between sessions (Dialysis days)
Diabetes Type 1, Type 2 or None Not chosen yet at first; until you pick, the app assumes type 1, so the Treating a low card stays available. Pick both before you ask for suggested targets
Warn at (% of limit) 80 % unless your team prefers another number when a day turns from "ok" to "near limit"
"About" targets: on target up to (% above) 0 % unless your dietitian gives you a number (0–10 %) how far above a one-number target, such as protein "about 56 g", still counts as on target (Targets and warnings)
Week starts on Monday or Sunday used by Plan and the shopping list

Then tap Save profile.

3. Set your targets

If your care team gave you numbers, type them into Daily targets and save. Those are your targets. Leave a box empty for anything they did not limit.

If not, tap Suggest targets. The app fills the boxes with guideline starting points and a note on each one, and it saves nothing until you tap Save profile (architecture contract). Take the numbers to your next visit and ask your team to change them.

Example: stage 4, type 1 diabetes, 70 kg, 170 cm

Target Suggested Why
Protein about 56 g a day (0.8 g per kg) with diabetes, not below 0.8 g/kg before dialysis (ADA 2026, Rec 11.3; KDIGO 2024, Rec 3.3.1.1)
Potassium 3,000 mg a review ceiling: only restrict potassium if your blood potassium is high
Phosphorus 1,000 mg
Sodium 2,000 mg the same at every stage (KDIGO 2024, Rec 3.3.2.1)
Calories 2,100 kcal (30 per kg) KDOQI's range is 25–35 kcal/kg (KDOQI 2020, 3.1.1)
Carbohydrate 236 g a day, 60 g per meal the app's default: 45 % of calories, split over four meal slots. There is no ideal share for everyone, so your diabetes team sets yours (ADA 2026, Rec 5.13). Carbohydrate per snack is empty until you type your team's number
Fiber at least 29 g a day 14 g per 1,000 kcal (ADA 2026, Rec 5.24); a goal to reach, never "over"
Fluid not tracked fluid limits start on dialysis

At a BMI above 25 (or below 18.5) the app uses an adjusted weight instead of your scale weight, and the first note says which weight it used (design note 05).

Which details change your targets

Profile → About you has optional details: birth month, the sex used in medical formulas, height, weight 6 months ago, activity level, frailty, pregnancy, and "I have had high potassium". On dialysis Kidneys and diabetes also asks for your urine volume (and on peritoneal dialysis your ultrafiltration and the calories from the dialysis fluid); without dialysis it asks for a transplant date if you have one. Lab results go in Lab results (Profile → Blood and urine tests). Each detail changes only some targets (design note 05):

Detail Changes Does not change
Age calories; protein from age 65; calcium only at stages 1–2 (a transplant kidney included) sodium, potassium, phosphorus, fluid on dialysis
Sex used in formulas calories; calcium at stages 1–2; the eGFR estimate protein per kg, sodium, potassium, phosphorus
Height and weight the weight used for protein and calories sodium, potassium, phosphorus
Activity calories everything else
Stage and dialysis protein, potassium ceiling, phosphorus, fluid sodium
Diabetes protein floor of 0.8 g/kg at stages 3–5 without dialysis; carbohydrate per meal sodium, potassium, phosphorus
Blood potassium potassium only everything else
Blood phosphate phosphorus only everything else
Urine output (dialysis) fluid only everything else
Low albumin, weight loss, frailty can raise calories and protein sodium, potassium, phosphorus
A1c, CGM numbers, UACR, bicarbonate nothing: they add notes only all targets

Labs matter more than age or sex for potassium and phosphorus. Sex never changes protein per kg, sodium, potassium or phosphorus (design note 05).

Each suggested number has a Why this number? link with the rule behind it, its source and grade; rules that are partly the app's own choice carry an Expert opinion badge. When a new lab result would change a suggestion, the app shows Review suggested targets. It never changes your saved targets by itself.

Do not use Suggest targets if you are pregnant, under 18 or newly transplanted

Nutrition needs are very different if you are pregnant or breastfeeding, younger than 18, or in the first 12 weeks after a kidney transplant. Your nephrologist, transplant team or a specialist dietitian sets your numbers then (Sex, fertility and pregnancy; After a transplant). Tick Pregnant or breastfeeding, add your birth month, or add your transplant date in your profile: the app then shows why it does not suggest targets and fills in no numbers. Type in your team's numbers instead (design note 05).

What to do

  • Fill in weight, height, stage, dialysis and diabetes, then Save profile.
  • Copy in your team's targets, or use Suggest targets and save.
  • On hemodialysis, tick your dialysis days and enter your fluid allowance in mL (1 cup = 240 mL; 32 oz is about 950 mL). Enter the weight-gain limit your team gives you in Settings → Weight and blood pressure (Weight and blood pressure; Fluid).
  • On peritoneal dialysis, choose Peritoneal so the app uses PD starting points.
  • After a transplant, set Dialysis to None, add your Kidney transplant date and the stage of your new kidney.
  • Update your weight and stage when they change, then check Suggest targets again.

Ask your care team

  1. "What are my daily limits for potassium, phosphorus, sodium and protein?"
  2. "Should I limit potassium at all, given my last blood potassium?"
  3. "How many grams of carbohydrate should I aim for at each meal?"
  4. "What is my dry weight, my fluid allowance and my weight-gain limit between sessions?"
  5. "Which weight should I use for protein: my scale weight or another one?"

Get help now if…
