SEVEN WAYS TO PLAY - Closest to X — stop the blind timer as close to the target as you can - Survival — endless rounds that tighten every time; one miss ends your run - Knockout — everyone buzzes, the furthest-off is knocked out, last player standing wins - Guess the Time — a hidden run plays, guess how long it lasted - Match the Time — hear an interval, then reproduce it by feel - Build the Time — stack start/stop runs until you hit the target - Tic Tac Toe — closest buzz claims the square DAILY CHALLENGE One blind target every day, the same for everyone worldwide.

Verdict
The clearest difference is ads: Blind Buzzer at none against ZeroIn's shown. ZeroIn's advantage is update cadence (every 5 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
