Verdict
The clearest difference is in-app purchases: Custom Fitness Timer at none against VoltTimer's 1. Custom Fitness Timer also leads on update cadence (every 4 days vs every 3 weeks) and iOS requirement (13.0 vs 18.6). VoltTimer's advantage is ads (none vs shown). On price and device support there is nothing between them.
