Verdict

The call

The clearest difference is in-app purchases: bigstopwatch at none against Relume Clock's 1. bigstopwatch also leads on ads (none vs shown). Relume Clock's advantage is update cadence (every 5 days vs every 9 months) and device support (3 vs 1). On price there is nothing between them.
