Verdict
The clearest difference is rating: Tapd at 4.0 against ReactionTimeChecker's 1.0. Tapd also leads on review sentiment (70% vs 33%) and ads (none vs shown). ReactionTimeChecker's advantage is in-app purchases (none vs 3) and update cadence (every 7 months vs every 19 months). On price and device support there is nothing between them.
