Logging fluid balance on peritoneal dialysis

If you are on peritoneal dialysis, keeping track of fluid is a day-to-day part of life, and many people are asked by their home-therapy team to keep a note of what goes in and what drains out. Kidney Tracker gives you a simple, private place to keep that record on your iPhone. You log each amount as a fluid entry, and the app totals your intake and output and keeps a daily net for you — so the running figure is there at a glance rather than worked out on paper. It holds no prescription and offers no clinical advice; it simply records and adds up the numbers you enter.

Fill, drain and a daily net

Record what goes in as intake and what drains out as output, both in millilitres, treating each as a fluid entry as you go through the day. The Today screen keeps a live running total of each and shows the net balance for the day, so you can see where you stand without doing the maths. Save the amounts you use most so common entries are a single tap, and let a configurable day-start hour line your daily net up with a clinic's 24-hour chart rather than resetting at midnight.

Weight, blood pressure and more

Alongside your fluid entries you can record your weight whenever you like and follow it on a chart, note systolic and diastolic blood pressure readings, keep a list of your medications with local reminders on your device, and jot down any blood results your team reads back to you. It all sits in one tidy place, so a quick look tells you how the day is going across everything you have been asked to watch.

You stay in control

Kidney Tracker never sets a target or a schedule for you. Any fluid target is a number you enter yourself, agreed with your own home-therapy team, and the app simply totals your day against it. Reminders are notifications on your own phone, and you choose the times. The point of the app is to take the arithmetic and the scraps of paper off your hands, not to make any decisions for you.

Private, and easy to share

There is no account, no sign-up and no tracking — everything you enter stays on your own iPhone. When a clinic visit or a phone review comes up, turn your records into a clean, printable report covering your fluid entries and daily nets, then print or share it; it goes only where you send it. If you would like the bigger picture, our dialysis overview and the haemodialysis page cover the other route too.

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.
