I love that my Thinkie gives me variety & is easy to use! Training my brain is important to me because I have ADHD, I'm in perimenopause, and I have seen family members struggle with cognite decline. So for more, "staying sharp" is really important as I age. I know brain training is an importance piece of my cognitive performance on a daily basis, but in the past I've always been bored by the idea of doing it through mindfulness or meditation. My favorite feature is the Brain Activity Tracker. When I'm done doing some Brain Games and have met my Brain Training goal for the day (which usually takes 10 minutes), then I use the Brain Activity Tracker which monitors my brain's activity while I do whatever task I want. I think it's cool to be able to see how my brain performs based on different tasks like reading, exercising, embroidery, working in a spreadsheet, cooking, etc. I use it a lot, daily in fact, because it doesn't take long at all. Plus, the ability to get an "age" for my brain (currently 57 but I'm only 45, so I've got some work to do!), is a great feature to help me be able to see in real time that I'm making progress to keep my mental agility strong as I age. I got one for my dad too!
