Before you say yes

Know your number before you pick up the phone

Put in the rate, the miles and the deadhead. Grumpy adds your fuel, truck note, insurance and wear, then tells you the break-even and the rate you should ask for. If it's short, he writes the counteroffer for you. Copy, paste, send.

Every number is an estimate built from what you enter. Confirm before you act.

What's in the app

Six tools. No spreadsheets.

Big buttons, plain words, one thumb. Built for a phone in a truck cab, day or night.

Load check

Profit per mile, break-even, target rate and a ready-to-send counteroffer.

Fine. Haul it. Don't get used to this.

Scale it

New drivers

Punch in your scale ticket. It tells you which way to slide the tandems or fifth wheel, and checks your KPRA.

Make the move, pay the three bucks, check it.

Broker check

Look up a broker's MC or DOT number in public FMCSA records, then run the Sniff Test for fraud red flags.

Check the broker before you check the rate.

Week

Your weekly report card: what you netted, cost per mile, the Grumpy Meter and a grade from A to F.

Good week. I'm suspicious.

Meet the crew

Two drivers. Same side. Yours.

Grumpy and Big Rig Roxy run their own trucks and their own way. Both are hell bent on getting trucking right.

Grumpy

Tired, dry, been everywhere twice.

  • Fine. Haul it. Don't get used to this.
  • You'd be paying to work. Let it sit.
  • Solid. Don't spend it all on truck stop chicken.

Big Rig Roxy

Quick, sharp, done with excuses.

  • Nice rate. For 1998.
  • Deadhead's not free. Put it in the rate.
  • Don't tell me it's a good lane. Show me the number.

Double-brokering is real

Thirty seconds can save you a load

The broker check pulls public FMCSA records: authority status, how long they've had it, and whether a bond is on file. The Sniff Test walks you through the red flags that show up before a load goes sideways, like a "dispatcher" who isn't on the rate con or a sudden change to payment details.

Just facts from public records and your own notes. No gossip, no blacklists.

  3. Check the broker before you check the rate.
  4. Coffee first.

Built by a driver

Made in the sleeper, not an office

Grumpy's Money Check is built by John, an OTR team driver who still spends most of the week on the road. It's made for drivers who just went from company driver to owning a truck, and want a straight answer on a rate without learning accounting.

Every screen gets tested where it'll be used: in a cab, on a phone, with one bar of signal and a cup of coffee going cold.
