Verdict
The clearest difference is in-app purchases: Digital Chess Clock at none against Chess Prep Pro Openings's 3. Digital Chess Clock also leads on ads (none vs shown) and update cadence (every 2 days vs fortnightly). Chess Prep Pro Openings's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price there is nothing between them.
