# AllMyBatteries vs Empty shell

The clearest difference is in-app purchases: Empty shell at none against AllMyBatteries's 3. Empty shell also leads on iOS requirement (11.0 vs 15.0). AllMyBatteries's advantage is device support (5 vs 3). On price and ads there is nothing between them.

Both are free to download. AllMyBatteries sells 3 one-off in-app purchases. Empty shell asks for nothing beyond the download.
