Tap!
Read full descriptionHide full description
Tap! is a simple, fast arcade game about tapping a target before it gets away. Each time you hit it, it jumps somewhere else on the screen, and it keeps getting quicker the longer you go. It's the kind of game you pick up for one round and end up playing for twenty. There are three game modes: Time Attack — you get 30 seconds to score as high as you can. Survival — you have three lives, and every target has a countdown ring. Tap it in time or you lose a life. Zen — no timer and no lives, just for relaxing and going after a long streak. As you play, hitting targets quickly in a row builds a combo that multiplies your points, up to 8x. Gold targets show up now and then and are worth five times as much. The higher you climb, the smaller and faster the targets get, and there are Easy, Normal, and Hard settings if you want to change the challenge. Tap! has Game Center leaderboards for each mode and achievements to unlock, and it keeps track of your best scores and overall stats. There are haptics and sound effects, and there are no ads, no accounts to make, and no internet needed to play. See how fast you can tap.

Verdict
The clearest difference is in-app purchases: Tap! at none against Nukleus's 4. Tap! also leads on update cadence (every 2 days vs every 5 days). Nukleus's advantage is device support (3 vs 1) and iOS requirement (8.0 vs 16.0). On price and ads there is nothing between them.
