Precision estimation trainer
Read the world by eye. Lock it in.
Tower Rush turns your gut feel for size, angle and distance into a measurable skill. Stretch the caliper, swing the needle, match the beam — then lock your reading and see how close you got.
How it works
Every screen trains a different instrument
Drawn straight from the drafting desk: blueprint grid, amber calipers, cyan reference beams. Fine-tune, lock, and compare.
Set your precision profile
Twelve mixed reads calibrate how your eye behaves. Stretch the amber caliper to the cyan beam, nudge with the fine +/− control, then Lock Reading. Tower Rush learns where you run long and where you run short.
Swing the needle to the mark
A cyan angle appears; you swing the gauge until it matches. The live readout climbs toward 90° as you close in — precise degrees, no guessing sliders. Angles, lengths and areas all use the same lock-and-score loop.
Quick drills and a daily challenge
Your home base shows rank, XP and a precision radar. Fire off a Length, Angle, Area, Height, Count or Proportion drill in seconds — or take the Daily Challenge: 10 mixed reads, one shot, and a streak to protect.
Turn real objects into drills
Photograph something you can measure, log its true size, then train your eye against your own shots. Record the reading, tag what it is, and Tower Rush builds custom drills from the world around you.
