# LongshotHD vs STL File Viewer Pro

The clearest difference is review sentiment: LongshotHD at 55% against STL File Viewer Pro's 10%. LongshotHD also leads on in-app purchases (none vs 3) and ads (none vs shown). STL File Viewer Pro's advantage is rating (4.5 vs 4.0) and chart position (#33 vs #142). On price, ratings volume, update cadence and device support there is nothing between them.

Both are free to download. STL File Viewer Pro sells 3 in-app purchases, starting at $1.99 per 7 days. LongshotHD asks for nothing beyond the download.

STL File Viewer Pro holds the better App Store score, 4.5 against 4.0. Both are backed by a comparable volume of ratings — 25 and 65 respectively. Written reviews complicate that: 55% of LongshotHD's written reviews are positive against 10% of STL File Viewer Pro's, so the app with the better star average is not the one people write more warmly about.

LongshotHD ships an update every 3 weeks, STL File Viewer Pro fortnightly. The most recent releases landed on September 26, 2026 and September 24, 2026 respectively.
