Verdict
The clearest difference is rating: STL Simple Viewer at 4.3 against iFilemonger's 2.8. STL Simple Viewer also leads on ratings volume (909 vs 16) and update cadence (every 5 months vs every 13 months). iFilemonger's advantage is in-app purchases (none vs 4) and ads (none vs shown). On price and device support there is nothing between them.

STL Simple Viewer holds the better App Store score, 4.3 against 2.8. That said, the two scores are not equally well evidenced: STL Simple Viewer has 909 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 42% of iFilemonger's written reviews are positive against 18% of STL Simple Viewer's, so the app with the better star average is not the one people write more warmly about.
iFilemonger ships an update every 13 months, STL Simple Viewer every 5 months. The most recent releases landed on October 17, 2026 and October 16, 2026 respectively.
