# FlickerSpec vs 100 Lights

The clearest difference is device support: 100 Lights at 3 against FlickerSpec's 1. 100 Lights also leads on iOS requirement (15.1 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. FlickerSpec sells 1 one-off in-app purchase and 100 Lights sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
