Read full descriptionHide full description
One target. 5.40 seconds, say. You hold the button and the clock runs. After a quarter of the target it turns grey — from there nobody is counting for you. Let go when you think the time is up. A hit takes you on, and it gets tighter: the allowed margin shrinks with every hit, from six tenths down to one. You have four lives. You do not get them back. Green means hit, red means missed — and land within five hundredths and you get a dead-on. You will see it. That is all there is. • A round takes seconds • No account, no ads, no purchases • Works without internet • Collects no data • Leaderboard with friends via Game Center, if you like Best with sound.

Verdict
The clearest difference is in-app purchases: HALT at none against Stack's 19. HALT also leads on ads (none vs shown) and update cadence (every 2 days vs every 11 days). Stack's advantage is chart position (#164 vs unranked) and device support (3 vs 1). On price there is nothing between them.
