History doesn’t load

App can’t read its own history despite having full health access. Sent logs to developer but no response

Keeping my hot husband hot

My husband won’t listen to me when I remind him to put on sunscreen/stay out of the sun, but he will listen to an app. Thanks for making this app so he will retain his youthful skin!

Response from developer

Thanks for the review! I'm sure your husband is trying his best!

Seems to have quit working

Worked for about a week but is no longer working. Reports 0 exposure daily now. Time to uninstall. Wasnt worth the $11.99.

Response from developer

Hi there, I'm disappointed to hear it isn't working for you. We've shipped out a number of improvements since then that should address any 0-exposure issues. Please give it a try and if it's still not working email us at hello@sunexpsosure.app to we can fix it!

Great app

Loved it

Response from developer

Thanks for the review!

Worthless

Another worthless app. It clearly says you can pair it with a compatible Apple Watch, but neither recognizes your watch, nor tells you how to connect the app to your watch.

Response from developer

Hi there, there are no special connection steps required to connect your Apple Watch beyond granting the Health permissions. Please reach out at hello@sunexposure.app and we can help get you setup!
