The one-time purchase is now called Scale House, named for what it actually unlocks: fifth-wheel slide, bridge formula check, saved trailer profiles, and the scale ticket log. Same purchase, same price — if you already own it, nothing changes.

About

You're on the scale, you're heavy on the drives, and there's a line behind you. TandemIQ tells you which way to slide the tandems and exactly how many holes. In four seconds. With no signal. $4.99 once. No ads — not now, not ever, including for people who paid. FREE, ALWAYS • Federal axle and gross legality check (12,000 steer / 34,000 tandem / 80,000 gross) • Trailer tandem slide solve — which direction, how many holes, and what every axle will weigh after FULL UNLOCK ($4.99, one time) • Fifth-wheel slide • Federal Bridge Formula check • Saved trailer profiles (hole spacing and pounds-per-hole vary by trailer) • Calibrate pounds-per-hole from a real scale ticket • Scale ticket log with photos THE DIRECTION IS UNMISTAKABLE "Move tandems 3 holes FORWARD." In big letters, with an arrow. Sliding forward puts weight ON the trailer tandems and takes it OFF the drives — get that backwards and you make the problem worse. TandemIQ never does. IT TELLS YOU WHEN SLIDING WON'T WORK If you're over gross, no amount of sliding fixes it. Other apps return an absurd hole count. TandemIQ says "CANNOT BE LEGALIZED BY SLIDING" and tells you why. WORKS WITH NO BARS There is no network code in this app at all. Airplane mode, dead zone, middle of nowhere — it works exactly the same. Always re-weigh after sliding. Estimates only — you are responsible for the legality of your load.
