I find myself having trouble finding words to express how Unique this App is for this ole man. Now Days due to my ole age and my Health issues it’s not easy for me getting around with my cane 🦯. Before I dare venture out into my world I need to know Mother Nature 🌬️ is really right for me! Sounds easy right, but it’s not and as my Health keeps changing so does the risk factor! So thanks to the Developer of this Unique Outstanding Design App I have learned more about my Heat Factors than I did not know before. The App to look 👀 at seems simple, but it’s not!
