# Sensor Viewer vs VibraScope

The clearest difference is ads: Sensor Viewer at none against VibraScope's shown. VibraScope's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Sensor Viewer sells 2 in-app purchases, starting at $0.99 per year and VibraScope sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
