Assembly gives every project car a home. Plan projects, track parts, and centralize all of your plans, photos, files, checklists and notes in one shareable place.
Assembly is the home for project cars. Plan projects, track parts, document modifications, organize maintenance, and keep a complete history for every vehicle in your garage.
Keep every part, project, note, photo, receipt, file, and update connected to the car it belongs to—so months or years from now, you'll still know exactly what you changed, why you changed it, and what comes next.
Whether you're planning an engine swap, documenting a restoration, organizing maintenance, fabricating custom parts, or simply trying to remember which part you installed three years ago, Assembly helps you keep the entire story together.
Most project cars are managed across notes apps, spreadsheets, photo libraries, receipts, forum posts, and memory. Assembly brings everything together in one place designed specifically for enthusiasts who modify, restore, maintain, fabricate, and continually improve their own cars.
Features
PLAN PROJECTS
Keep plans, research, notes, photos, tasks, and parts together from start to finish. Assembly was designed for complex, long-term projects that evolve over months and years—not just routine maintenance. Whether you're restoring a classic, fabricating custom parts, building an engine, or developing a track car, Assembly grows with the project.
TRACK PARTS AND MODIFICATIONS
Organize parts you need to buy, parts waiting to install, and parts already installed. Record part numbers, costs, purchase links, installation dates, mileage, receipts, and notes to create a complete history of your car.
CENTRALIZE YOUR DOCUMENTATION
Instead of scattering information across notes, checklists, spreadsheets, emails, and photos, keep every modification, maintenance record, specification, and document attached to the vehicle itself. Always know the current state of your project car.
STORE PROJECT FILES
Upload wiring diagrams, CAD files, receipts, manuals, PDFs, and other files related to your projects. Storage limits depend on your selected plan.
CONNECT WITH OTHER ENTHUSIASTS
Follow people working on similar project cars. Browse project updates, photos, documentation, specifications, and community discussions. Share your progress, learn from real project histories, and help others tackle similar challenges. For enthusiasts who still love the classic forum experience, Assembly also preserves a searchable project history that feels more useful than a traditional build thread.
Plans
• Start tracking your first project car for free.

If you find yourself reminiscing of the days when forums existed. Or looking for a way to catalog and organize your project car journey. Then this is the app for you. Track the progress of your projects, what you need to do, what you need to get, all while keeping a history of what you’ve done. See what other like minded car enthusiasts are doing on their projects without all of the unwanted noise and nonsense of social media.
The only car app made for projects.
The Full Banana
I tried (and failed) for years to keep good records for all my project cars until using this. No other car app is made for the type of detail involved in project cars. Maintenance loggers don’t work for me; Assembly does.Assembly replaces and consolidates all of the info I’ve had stored across the Notes app, email, camera roll, and files stored across Google Drive, iCloud, and the other 5 places I forgot about. I’m done making and remaking checklists for projects only to lose the key details that I’ll inevitably need to find again when I revisit that part of the car, or answer a question from someone about the project.
So far LOVE IT.
