Verdict
The clearest difference is review sentiment: Souv at 100% against Longdistan's 0%. Souv also leads on update cadence (every 3 days vs every 2 weeks). Longdistan's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.
