Verdict
The clearest difference is in-app purchases: One Second Challenge at none against Perfect Circle's 7. One Second Challenge also leads on ads (none vs shown). Perfect Circle's advantage is update cadence (every 4 days vs every 6 weeks). On price, device support and iOS requirement there is nothing between them.
