Verdict
The clearest difference is in-app purchases: Image Saliency at none against Beacon Alert's 1. Image Saliency also leads on update cadence (fortnightly vs every 48 months). Beacon Alert's advantage is ads (none vs shown) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
