⚡ HitchMate: Towing Safety Telemetry — Tongue Weight, WDH Alignment & Pre-Trip Checks

HitchMate

Ultimate Automotive & Towing Safety Telemetry Tool

Real-time towing physics, weight distribution and axle-load diagnostics in one modern dashboard — tongue weight, sway risk, tyre pressure and a pre-trip check before you roll.

Built around the five things a rig needs

One tab each for weights, rigs, weight distribution, tyres and the pre-trip walk-round.

Weights tab

Tongue Weight & Sway Telemetry

Real-time tongue weight percentage and absolute load monitoring. A visual safety gauge highlights the safe 10-15% band and raises hazard or overload warnings as you move out of it. Interactive cargo and water balance controls cover fresh, grey and black water loads.

Rigs tab

Rig & Fleet Management

Add and manage your own tow vehicles and trailers with full sticker-rating tracking — curb weight, GVWR, GCWR and wheelbase — and scan the VIN to fill the plate. Switch your active rig in one tap.

WDH tabPro

Weight Distribution Alignment

Work out the exact front-axle load restoration percentage from your scale readings, then follow step-by-step shank drop and rise suggestions to bring the rig back into alignment.

Tyres tabPro

Tyre Pressure & Axle Load Calculator

Calculate the per-tyre load from your actual axle weights and get recommended cold tyre pressures for the load you are actually carrying, not a generic door-jamb figure.

Pre-Trip Safety Checklist

A complete walk-round checklist — coupler latch, safety chains, breakaway cable, lights and tyres — ending in a smart safety readiness status before you move.

Safety, measured rather than guessed

The numbers that decide whether a rig is safe to tow are all shown on one dial and one readiness status.

The 10-15% green band

The gauge marks the safe tongue weight window directly on the dial, so balance is something you can see at a glance instead of a number you have to interpret.

Hazard & overload warnings

Move outside the safe range and the gauge escalates — hazard warnings for marginal loads, hard overload warnings when you are past the limit.

A single readiness status

The pre-trip checklist finishes with one clear readiness status, so you know whether to roll or fix something first.

An aligned front axle

WDH alignment reports how much of the original front-axle load has been restored, and the shank drop or rise that would restore the rest.

HitchMate is a calculation and record-keeping aid. Always confirm against your vehicle and trailer manufacturer's ratings and a certified weighbridge before towing.

HitchMate questions

What is the safe tongue weight range?

HitchMate treats 10-15% of the trailer weight as the safe tongue weight window and marks that band on the gauge in green. Move above or below it and the app flags the load as a hazard.

Which features are free?

Basic tongue weight calculations, the tongue weight gauge and active rig selection. Everything beyond that — WDH alignment, the tyre and axle load calculator and the pre-trip checklist — is part of Pro.

What does Pro unlock?

Weight distribution alignment with front-axle restoration percentages and shank drop/rise suggestions, the tyre pressure and axle load calculator, and the full pre-trip safety checklist.

How does the 14-day trial work?

Pro features open on a 14-day free trial. When the trial ends you choose whether to unlock Pro — nothing is charged automatically up front.

Do I need scale readings?

For WDH alignment, yes — the front-axle restoration percentage is calculated from your scale readings. The tyre calculator works from your actual axle weights, so accurate weights give accurate pressures.
