Day-to-day tracking with chronic kidney disease

Living with chronic kidney disease often means keeping half an eye on a handful of everyday numbers between appointments. Exactly which ones, and how closely, varies from person to person and is something your own kidney team will guide. Kidney Tracker gives you a calm, private place to keep whatever you have been asked to watch — fluid, weight, blood pressure, your medications and the blood results you want to follow — all in one app on your iPhone, with the adding-up and charting done for you so the record stays effortless.

Fluid, weight and blood pressure

Log your drinks in millilitres and, if you have been asked to, your output too. The Today screen keeps a live running total and shows your net balance against a daily target you set yourself. Record your weight whenever you like and watch it plotted across days and weeks, and note systolic and diastolic blood pressure readings, with pulse if you take it. Each entry is timestamped and charted, so a string of readings becomes a simple trend you can scroll back through rather than a list to decipher.

Medications and blood results

Keep a list of your medications and set local reminders on your device so a dose is easy to remember — the reminders are notifications on your own phone, with the times set by you, and the app never advises on what to take. You can also note the blood-test results you want to keep an eye on, such as the values your clinic reads back to you, and follow them over time on a chart. It is a tidy personal record of the numbers that matter to you, not a clinical interpretation of them.

Charts that make patterns clear

Every metric you log can be viewed as a chart, so a change over weeks is visible at a glance rather than buried in a column of figures. History is browsable by day, and you can scroll back to any date to see exactly what was recorded. A Home-Screen widget keeps today's fluid total in view, an Apple Watch complication puts it on your wrist, and Siri lets you log a drink by voice.

Private, and ready for your appointment

There is no account, no sign-up, no analytics and no advertising — everything you enter lives on your own iPhone and works offline. When a review comes up, turn your records into a clean, printable report covering everything you track, then print or share it; it goes only where you send it and the app keeps no copy. You can read the full privacy policy for the details.

Kidney Tracker is a personal record-keeping tool. It is not a medical device and does not provide medical advice — always follow your own clinical team.
