# STL Viewer vs QReader

The clearest difference is ads: QReader at none against STL Viewer's shown. STL Viewer's advantage is chart position (#173 vs unranked) and iOS requirement (15.0 vs 26.5). On price, in-app purchases and device support there is nothing between them.

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