Handy & Buggy

Male fertility can be difficult to wrap your head around and this app is filled with loads of helpful information. With a few minutes of filling out information you can get a personalized list of things to work on.
The app does have some usage issues and crashes often on my phone (I am updated to the most recent iOS), it’s difficult/impossible to skip some questions if you don’t have the info, and many questions only allow you to select one option when multiple will apply.

App has great advice and feedback but crashes every 45 seconds or so. Not worth it.

Excellent app!

The app helps to consolidate the very wide and confusing world of male fertility down to a digestible and clear format. It gets into the nitty gritty of your lifestyle and health and gives great tips for trying to improve your odds of conception.

Can't recommend enough for those trying to understand this adventure you're on.
