Software we build and maintain at Skunk River Restorations — mobile apps for enthusiasts, and the software that runs our own shop.
LastDrive
The garage app for the vehicles you don’t drive every day. Track maintenance, documents, fuel, tires, and reminders for every vehicle in your garage — and know at a glance which ones need attention or a drive.
Fuel Pre-Pay Estimator
Know exactly how much to pre-pay before you fill up. Photograph your fuel gauge, record how many gallons it takes to fill, and the app tells you the dollar amount to pre-pay at the pump — no guessing, no coming up short.
TachoSpeed
A GPS tachometer and speedometer for vehicles with a working tachometer but a broken or missing speedometer. Calibrate once and TachoSpeed turns your phone’s GPS into a live analog tach dial — RPM scale, equivalent road-speed scale, and digital GPS speed all on one gauge.
RaceCarLogBook
The offline race-session logbook for amateur racers. Keep a structured record of every car you race, every event you enter, and every session you turn — with lap times, results, photos, per-track personal bests, and an FIA-style Driver Resume PDF ready when a licence application asks for one.
GearRatio
Measure your rear axle (final drive) ratio with just your phone and your tachometer — no gears to count, no diff to open. Hold a steady speed at a known RPM, tap Capture, and GearRatio pairs GPS speed with your tire size to compute the ratio. It also computes the exact gear-ratio setting to enter on a DynoJet 224xLC chassis dyno.
WireForge — in development
Bring vintage wiring diagrams back to life — in colour, in vector, and runnable. WireForge produces modern, readable wiring diagrams for pre-war and early-postwar cars, paired with a Wire Harness Simulator for iPhone, iPad, and Mac. Tap the switches and fuses, watch the circuits energise, and cut a wire to see what stops working — diagnosis before you climb under the dash.
SpannerSoft — in use at our shop
SpannerSoft™ is our shop management system — work orders, estimates and invoicing, customer and vehicle records, vehicle photo archives, inventory and purchase orders, vendor invoice importing, payroll time clock, and a live shop board with bay scheduling and a customer waiting list. Built by us, for the way an independent restoration shop actually works, and in daily use running Skunk River Restorations since April 2026.
SpannerSoft is not publicly available at this time.
