# QR Spy vs TimelineWorker

The clearest difference is ads: QR Spy at none against TimelineWorker's shown. TimelineWorker's advantage is device support (3 vs 1) and iOS requirement (15.3 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
