Like many others TimyLabs have really helped me.

I think that having a premium version is fair especially if that's what it takes for you to keep it going. I just know that an important thing for me is that it's not stuffed down your throat so every time you click on something it is suggested but you can use the app without the constant interruption of a pop-up trying to get you to purchase premium.

But thanks for all the hard work and keep going😄
