## What is DynoLog?

DynoLog is the build journal for people who actually wrench.
Whether you're chasing a quarter-mile time, documenting a full restomod, or just keeping honest track of where the money's going, DynoLog gives your build a home. No spreadsheets. No scattered photos. No forgetting what you paid for that turbo eight months ago.
TRACK YOUR BUILD

Log every modification with cost, vendor, install date, and notes. Watch your total investment add up (whether you want to see that number or not). Keep receipt photos attached to each mod so nothing gets lost.
LOG YOUR RUNS

Record performance runs — ET, trap speed, horsepower — and see them plotted over time. Correlate mods to gains: see exactly which changes moved the needle and by how much.
DOCUMENT THE JOURNEY

Your build's full timeline in one place. Every mod, every run, every milestone, in order. Look back at where the car started and how far it's come.
SHARE YOUR RIDE

Publish your build to a clean public page you can share anywhere. Browse the community feed, follow other builders, like and comment on builds that inspire you. Real builds from real enthusiasts.
WORKS WITH HOWFAST

Already running HowFast? Send your performance runs straight to DynoLog — by direct link, file export, or background cloud sync — and keep all your data in one build journal.
