Get your own christmas tree! By using this app, you can quickly set up a Christmas tree about 2m high. However, ornaments of the tree must be obtained with a slot machine. Let's challenge the slot by tapping the boxes which is hanging from the beginning. If you can match the symbols, you will get a nice ornament. But If you fail, your tree will be decorated with junk objects. Ornaments can be decorated in 35 places in all. If you can decorate everything cleanly, you will be able to get a special ornament on the top of tree. * This application requires iPhone compatible with AR function (iPhone 6s or later) .

Verdict
The clearest difference is price: Air Tree at Free against Jack's $0.99. Air Tree also leads on update cadence (every 12 months vs every 30 months). Jack's advantage is ads (none vs shown) and device support (4 vs 2). On in-app purchases and iOS requirement there is nothing between them.
