# Variable Calculator vs Digital Clock

The clearest difference is in-app purchases: Digital Clock at none against Variable Calculator's 1. Digital Clock also leads on ads (none vs shown). Variable Calculator's advantage is iOS requirement (15.0 vs 18.1). On price and device support there is nothing between them.

Both are free to download. Variable Calculator sells 1 in-app purchase, starting at $1.99 per month. Digital Clock asks for nothing beyond the download.
