Verdict
ASL and ISL Journey both sit at 4.3 stars, but that hides the real split: 100% of ASL's written reviews are positive against 50% of ISL Journey's. ASL also leads on ads (none vs shown) and monetization model (free vs ad-supported). ISL Journey's advantage is update cadence (every 4 months vs every 29 months). On price, rating, ratings volume and in-app purchases there is nothing between them.
