This is quite simply the best organic structure drawing tool on the smartphone today. The app is very easy to use and control and it gives very good-looking drawing with minimal distortion and proportional discrepancy in the structures. The structures obtained from the app are equivalent to those drawn on a desktop by the regular organic structure drawing program. This is from my own experience of having used such program for over twenty years.

Whatever happened to the option of bringing over a bond to another bond and having them attach to themselves in a new bond. I would press the magic wand with the stars in the right corner and it would reorient the entire molecule based on the bond order and sp configuration. That option seems to be gone, as now all I get is a big blue dot that never goes away when I move one bond over to another to make a new bond between them. Now when you press the magic wand, the bonds break apart to original

Hello. This is may because the two bonds are not merged together. Make sure the bonds are joint and then use the magic wand it will work.

If we are talking about how the app delivers, its pretty good actually maybe beyond. The app isn't laggy and has all the features that you need to draw. I guess the only drawbacks would be sometime you need to login your account every single time you use it. Idk if its only happening to me, but yeah it keeps happening. Overall the app looks great and I hope that they fix those issue both on the pc and mobile. Since I use both app in my pc and mobile.
