Does the job.


I wanted to track input and output in same place and this allows me to do that. The iUFlow device is not available for purchase and I wish they would get rid of the big ‘plug in device’ button. The app prompts you to tell it the hours you sleep but not til the next evening. It would make more sense to prompt when you open the app for first time that day. Also, you can go back and add events and change times but can only add ‘first event of the day’ note and ‘this occurred after going to sleep’ in edit mode. So I can go into the app in the morning and tell it I peed at 4:00 am, but then have to save that event then edit that note to mark it as one that happened after I’d gone to sleep. Overall, the app does the job but is rather clumsy to use and not at all appealing.

Thank you very much for your feedback. The app works best together with the iUFlow device but of course it can be used without it.
Marking night events is done automatically. This is the reason why when you open the app during the day, you are asked to enter last night's sleeping time.
Please contact us at for more information.

Useful app for bladder diary and measurement


I was looking for an app to keep bladder diary. The app was recommended on a forum, so I gave it a try. I was looking for a way to monitor drinks and the outputs. I found the app useful for measurement and monitoring. It is fairly easy to fill a bladder diary with the app, measure, monitor the bladder and drinks. I am planning to use the app with the iUFLow device (have not ordered yet).

I gave it a try


I like this better than IP Voiding Diary app.

I gave it a try, but I kept forgetting to record when I pee. You can’t go back and add an entry.

Instead I use the HoursTracker app to keep track of how often I urinate. No joke. I have bladder problems and the medical apps just aren’t flexible enough. When I forget to record an event I can go back and add it whether it was an hour ago or eight hours ago using HoursTracker.

Thank you Dedwarmo for the valuable feedback! You can always add past events by tapping on the [Time] button on the top of the add Pee screen. You can also customize the alarms frequency to fit better. If there is a need, feel free to email us at so we can instruct you on this. Thanks again ;) iUFlow team
