Easy and private to use!

Love I can email my doctor the report. Customer service has been spot on when I’ve had questions. Looking forward to the continued updates and app improvements.

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.

Developer Response ,

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.

Insists on using my microphone!

I don’t have nor want the device that goes with this, yet this app still insists I need to allow it to access my microphone (who wants a device you have to plug into your microphone anyway?! Does it record you peeing?!). I deny it access and it asks every time I open the app and redirects me to settings to allow access. It’s only after I close settings (without giving mic access) that I can finally use the app to log my input/output. My music will even stop when I open this app. It also asks me to rate it every time it opens. Well here it is! It could be a useful simple app without these annoyances!

Developer Response ,

Thanks for the feedback! It sounds like you are using an old version of the iUFlow app. Please Update it. Feel free to contact us at , so I could instruct you on how to have the app to fit perfectly for your needs.
Mic permission was needed by iOS in the past. but no more. Thanks again for letting us know about that. You're more than welcome to enjoy the app even if you don't need the iUFlow device ;)
