Aim Trainer has 13 aim and reaction modes, including close-range and long-range crosshair drills and a swipe flick drill, each with its own global leaderboard. A calibration drill measures your device's input delay once and subtracts it from every reaction time, so results compare across devices.

In Classic 30s, circles appear at random spots and you tap each one before it vanishes. Targets shrink and speed up as time runs out. Consecutive hits bring the next target sooner, so the score ceiling rises with your skill, and a miss resets the combo. Hits show a burst, a haptic tap and an optional sound, and a ring inside each target shows the time it has left.

In Sweet Spot, each target is a flat training-dummy bust. Only its head scores, and tapping the body counts as a miss.

Missed taps count toward accuracy. Each result shows your score, average reaction time, hits per second, a miss breakdown, your global rank, and how the run compares with your last comparable run and with your best. There are five tiers: Elite Sniper, Sharpshooter, Marksman, Recruit and Novice.

Every mode has a global board, a daily board (reset at 00:00 UTC) and boards by country. You play without an account. Board rows and duel opponents show a 4-character tag and a country code, plus the two-word name and icon of players who saved the optional profile in Settings.

Ranked 1v1 is asynchronous: it gives you the targets of a Classic run another player left earlier for 30 seconds, or a BOT when no record is near your points. That run's hits reappear at the same spots, and both hit counts show as two numbers. Wins add points and losses take them away across six leagues from Bronze to Master, and leaving a started duel is a loss. Your ranked Classic runs become opponents for other players, who see your tag and your profile if you saved one. The duel points board lists players with 5 or more duels in the last 30 days.

Flick has you tap targets that alternate left and right, and Dual puts targets on both sides for two thumbs. Rapid Tap (10s, always portrait) counts taps with up to two fingers and shows your taps and best second.

Survival swaps the clock for a health bar: each escaped target costs health and the run ends at zero. Every 10 hits the level rises and targets get faster and smaller, with no last level. It works in six modes, with its own boards by level.

Six crosshair drills sit together on the Play tab and run in landscape. In Crosshair you swipe to turn the view and tap the screen or a FIRE button to shoot. Close Range puts one strafing, jumping target up close that takes 3 hits to clear. Long Range spreads two small, distant targets across a wide view. In Swipe Flick you swipe the target into the crosshair and lift your finger to fire. In Tracking you drag to keep the crosshair on a moving target, scored by time on target. In Lead Shot shots take a moment to land, so you aim ahead of running, jumping targets. Every other mode except Rapid Tap can run in landscape too.

The app has four tabs: Play, Rankings, Stats and Settings. Stats keep your best for each mode, a reaction time trend and your recent runs. You can share a result as an image card and build a day streak by playing on consecutive days. Classic Practice is an untimed warm-up that gives a summary whenever you stop.

Settings cover sound, haptic strength, the crosshair look, target color, aim sensitivity, ranking country and a dark or light theme for the menus and results. Play screens always stay dark.

All 13 modes can be played without a purchase. Aim Trainer Pro, one optional one-time purchase, removes ads and unlocks Custom Training and Detailed Stats. It also adds two more sound packs, free crosshair editing and five more crosshair presets. You can restore it at any time, and Pro features added later are part of the same purchase.
