Verdict
The clearest difference is price: ASM Pocket at Free against STL Viewer's $0.99. ASM Pocket also leads on in-app purchases (none vs 5) and iOS requirement (13.0 vs 17.0). STL Viewer's advantage is update cadence (every 6 weeks vs every 25 months) and chart position (#177 vs unranked). On ads and device support there is nothing between them.
