Bridge Bidding

I was looking for an app for both my own practice and for my bridge students. This is NOT it. The app uses a typeface so small one needs tweezers to tell the letters apart (on my Mac). Aside from that, there is only one base bidding system loaded, 2/1, which I don’t play or teach. There’s a button to download a different system from the web, but that was apparently not functional. ADDING a system is effectively impossible b/c one has to start from scratch. The app shows lists of the seven levels and five strains. You pick one of each and define it - but I saw no way to add point ranges or any other limiting factors. There was no point in my looking any further. If the developer comments on this review I’ll consider that input and take another look.
