Verdict

The call

The clearest difference is in-app purchases: Thunder at none against Digital Clock's 3. Thunder also leads on ads (none vs shown). Digital Clock's advantage is update cadence (fortnightly vs every 2 months) and device support (4 vs 2). On price and iOS requirement there is nothing between them.
