Tracking fluid, weight and meds after a kidney transplant

A private place to record the daily numbers your transplant team has asked you to keep an eye on — and to add them up without the maths.

The early weeks after a kidney transplant tend to come with a lot of recording. Many people are asked by their transplant team to write down how much they drink, how much they pass, what they weigh each morning, their blood pressure, and the medications they take. Kidney Tracker gives you one tidy place to keep all of that — without juggling scraps of paper or a notebook by the kettle. It does the adding-up for you and shows the totals at a glance, so the focus stays on living your recovery rather than doing sums.

Fluid in and out

In early recovery your team may ask you to record both what goes in and what comes out, often to a tight schedule. In Kidney Tracker you log every drink and every measured output in millilitres, and you can save the amounts you use most so a common mug or glass is a single tap. The Today screen keeps a live running total of intake and output and shows the net balance against a target you have set with your team. If your clinic works to a 24-hour chart that does not start at midnight, a configurable day-start hour lets your totals line up with theirs.

Daily weight

A daily weight, usually taken at the same time each morning, is something many transplant teams ask for. Record it in a couple of seconds and watch it plotted over days and weeks. Seeing the line rather than a column of numbers makes a steady change easy to notice and easy to talk through at your next appointment.

Blood pressure and medications

Note systolic and diastolic readings, and pulse if you take it, and each entry is timestamped and charted. You can also keep a list of your transplant medications and set local reminders on your device so a dose is easy to remember at the right time. The reminders are notifications on your own phone — nothing goes through a server, and the app never advises you on what to take or when. You set the times to match the instructions you have been given.

Blood results you want to follow

After a transplant there are usually blood values your clinic reads back to you at each visit. You can note these down and follow them over time on a simple chart, keeping a personal record of the numbers that matter to you, all in one place alongside everything else.

One report for your appointments

When a clinic visit comes up, turn your records into a clean, printable report covering fluid, weight, blood pressure, medications and blood results. It is generated on your device and goes only where you choose to send it. Everything stays on your iPhone — there is no account, no sign-up and no tracking — so you stay in control of a record that is, after all, deeply personal.

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.

Common questions

Yes. You can log every drink as intake and every measured output, both in millilitres. The Today screen keeps a running total of each and shows your net balance, which is often what an early-recovery chart is built around.

No. Kidney Tracker never sets a target for you. You enter a daily target that you have agreed with your own transplant team, and the app simply totals your entries against that number.

You can keep a list of your medications and set local reminders on your device so a dose is easy to remember. The app does not advise on doses or schedules — you set the times yourself, based on your team's instructions.

Yes. You can generate a printable report on your device covering fluid, weight, blood pressure, medications and blood results, then print or share it. The app keeps no copy and the developer never sees your data.
