Verdict
The clearest difference is in-app purchases: Chkob at none against Submarine Simulator's 4. Chkob also leads on ads (none vs shown). Submarine Simulator's advantage is update cadence (every 3 days vs monthly) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
