A simple daily weight log

If your clinical team has asked you to keep an eye on your weight, the hardest part is rarely the weighing — it is the keeping of the record. Scraps of paper, a note on the fridge, a half-remembered figure from last Tuesday: none of it adds up to something you can look back over. Kidney Tracker turns the daily weigh-in into a single tidy log and draws it as a chart, so the pattern is there whenever you want it.

Record a weight in seconds

Open the app, enter today's figure, and you are done. Each entry is timestamped, so weighing at the same time each day builds a consistent record without any extra effort. There is nothing to set up, no goals to configure, and no prompts nudging you towards a number — the app simply holds what you give it.

See the line, not a list

Every weight you record is plotted over days and weeks. A chart makes a gradual change far easier to notice than a column of figures, and it makes the difference between a wobble and a trend obvious at a glance. When you scroll back, you can see exactly what was recorded on any given day, which is useful when something you want to discuss happened a fortnight ago.

Ready for your appointment

When you have a clinic visit coming up, you can turn your log into a printable, shareable report. It is generated on your device and goes only where you choose to send it — the app keeps no copy and the developer never sees it. Instead of trying to recall the last few weeks, you can hand over or talk through a clear record of exactly what you weighed and when.

Part of a bigger picture, if you want it

Weight rarely travels alone. The same app lets you log fluid in and out, blood pressure, medications and blood results, so if your team has asked you to watch more than one thing, it all lives in one place rather than scattered across different notebooks and apps. You can keep it to weight alone, or add the rest as your needs change.

Private by default

There is no account, no sign-up, no analytics and no advertising. Everything you record stays in a database on your own iPhone, which means you are in control of it. Deleting the app removes the data with it, so it is worth keeping your device backed up while you rely on the log. For a quick check, a Home-Screen widget and an Apple Watch complication can keep today's figures close to hand.

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.
