"App is not intuitive for how to do certain things. Thought I couldn't add back entires but you can, the date acts like a scroll field but isn't."
"I selected 'Yes' and entered the amount, but then when I tried to scroll down to enter the date, the keypad is in the way and there's no way to proceed. This is a very poor design"
19% of negative reviews mention this issue.
"It is currently pouring down rain and flooding outside where I live, the sky is overcast, completely cloudy. Yet the Dminder app assures me UV is available"

"I've been using the app for a month but all of my data was lost because I upgraded my phone and there is no login for the app."

11% of negative reviews mention this issue.
"the features available in the Pro version (which I paid to upgrade) are no longer available in Pro, and now I must upgrade to Premium? Are you kidding me?"
"They have added ads which I would understand but they put buttons on the ads that makes you think you can skip them or click out of them when you really can't. Some of the ads are over a minute long."
Design and usability issues driving negative reviews.
Users get trapped on screens with no back button, navigation blocked by alerts, or settings pages with no save/exit option
"When it sends alerts to tell you that you have reached the maximum exposer, the message blocks all access to the application screen and can not be circumvented."
Settings randomly reset, keyboard blocks input fields, date pickers are hidden, and entered data doesn't save properly
"When you lose weight your BMI numbers go down but when I change my numbers in this app it changes back in three hours to your old numbers! What gives?"
Reminders rarely work, Apple Watch functionality broken, session tracking stops unexpectedly
"Despite reminders being set for my phone and watch, it only reminds me of D being available maybe 5% of the time. The watch app suddenly stops my sun session for no reason"
Video tutorials are outdated, boring, and don't match current app version; no contextual help or tooltips
"Video help files are for an obviously outdated version of the app and offer little assistance."
