Recently I realised that I did have mild ADHD, so set out looking for a digital product that would suit me I "road tested" this product, fully expecting to refund it like most others. Surprise! It worked. It is simple enough, yet complex enough for my brain to work with. Try it yourself. Oh, and here is the cruncher - I had already bought it a LONG time ago. It suits me so well I bought it again to support the dev. It, for me, is that good.
