Read full descriptionHide full description
【Quickly】 In this mode, players compete to see how many consecutive hits they can make within a time limit. 【Blindfold】 This is a mode in which you hit the specified number of times in a row. The accuracy of your count is important because you cannot see how many times you have hit the button in a row. 【Whack-a-mole】 In this mode, players hit randomly moving targets in rapid succession. The ability to respond immediately to a moving target is important.

Verdict
The clearest difference is ads: Line at none against Rapid Tap Challenge's shown. Line also leads on iOS requirement (10.0 vs 15.5). Rapid Tap Challenge's advantage is update cadence (every 6 days vs every 21 months). On price, in-app purchases and device support there is nothing between them.
