Altough, based on user reviews, it seems to have problems with other devices as well.

I belive your best bet is to hope that there will be an update that will make the game less memory consuming and/or more stable.

Update: A new patch, 1.0.3 came out July 10th. This may help if you have a supported device. I've found the game much more stable after the patch.

• In the beginning (up to about 50 dwellers) you should have about an equal number of each production room type, so one power for each food and water.

• When expanding, you should usually build the power room first, so that you have enough power to activate a new food and water room.

• Extending a room (i.e. building a new one next to an old one) is more efficient per dweller than placing singles.

• Just building a room doesn't make it produce anything, it is actually only a dweller's stat that produces something. For example, in power rooms the production comes from the strength stat. One power room with three strength 3 dwellers will produce the same as one power room with one strength 9 dweller.

• Rooms produce depending on the amount of the main stat, not the number of rooms. So for example, one power room with dwellers totalling 10 strength will produce the same per minute as two power rooms of equal size and level as the first room if they contain a combined total of 10 strength. However, using two power rooms instead of one will cost more to build!

• To make dwellers happy, keep them in the room they have the strongest stat in (their "talent"). If two stats are equal, the left stat takes precedence (left in the sequence "S-P-E-C-I-A-L"). You will see if a dweller likes a room by the green corners of the room when you move a dweller to it. You can also make dwellers happier by successful rushes (but sadder by failed rushes) or by making them have children (both parents).

  • The main stat for a dweller includes any outfit bonuses. This means that you can use outfits to change which room a dweller prefers by giving them the right outfit. This is important, since it is more important to keep your production balanced than it is keeping your dwellers happy, but by using outfits you can achieve both!
