Loco Coco! ,

I love this app so much!

I first got it after getting a little far sighted in my 40s. The 3-minute eye test game, although a little monotonous, does wonders for my vision. I see results IMMEDIATELY afterwards. I would just play one game every night, but occasionally forgot or was too lazy to do so. Now with iOS 15, there is a home page widget, which I really love! I just glance at the widget for a few seconds several times a day and my eyesight is sharp. The widget is always there and reminds me to do this. No reading glasses needed!
