MolView is a website (and it works on iPads too!!) that allows you to build molecules and see what they would look like in a variety of views. Even better, it has a giant list of compounds, molecules and atoms that you can choose from.
There is a slight learning curve when building your own molecules, but once you figure it out it's pretty easy. All you need to do is to drop some atoms on the screen and then choose the bond type and connect the two atoms. You can get fancier and start with some fragments (as the site calls them). These are you basic carbon rings and things like that.
If you need to to have all of the directions spelled out for you, you can view the user manual here. You might be more a visual learner and, if so, you can view their YouTube channel for some quick videos. Here is an overview video of what the site has to offer.
