For solo and mobile mechanics

Less desk work.
More time to get business.

One Wrench Pro is the iPhone app that does the paperwork around every job (the inspection report, the quote, the invoice, the check-ins and the books) so your evenings go to cars and to the next customer, not to a laptop.

Coming soon to the App Store

The day it gives back

Five pieces of desk work the app takes off your hands, from the first look at the car to the month's numbers. Every screen here is from the app, filled with a sample shop's customers and prices.

1 · Inspect

The inspection report writes itself while you work.

Mark each item OK, watch or replace, snap the photo, type the reading. When you're done, you have a clean report with your logo and the photos, ready to send as a PDF.

No writing it up at night. The customer sees what you saw, and the report sells the work for you.

Coming The report on a private link they open from a text.

An inspection in the app: a job opens its inspection, the front brake pads are marked replace with a 3 mm reading and three photos, and the customer's report comes out with the findings and the shop's name on top.

2 · Quote

The quote is done before you leave the car.

Your findings turn into a quote with one tap, with the parts, the labor and your margin on it. Send the PDF as a text from your own number. When they say yes, one tap marks it approved.

No retyping what you already wrote down. You see what to order and what it makes you.

Coming Customers approving online from the text, with a deposit by card.

A quote in the app: the parts, labor and margin for a front brake job, then marked approved in person, with the parts to order.

3 · Invoice

The invoice goes straight to the books.

The invoice is built from the quote, so there's nothing to retype. Mark it paid another way and it lands in the books on the spot. Money still owed stays on one list, with the reminder text ready to go.

No pile of invoices at the end of the week. You can see who owes you, and the reminder is already written.

Coming Card payments on your own Stripe account: pay links, deposits and saved cards.

The money-owed screen with two unpaid invoices and a Text a reminder button on each; an invoice marked paid another way; and the same invoice showing paid and posted in the books.

4 · Follow up

Watch items come back as next month's work.

The yellow item you found last month comes back as a check-in when it's due. The text is already written and addressed: one tap in Messages and it's sent from your number. On my way and running window texts work the same way, with a drive time.

No more forgotten follow-ups. Nothing falls through.

Coming Reminders, receipts and check-ins that go out by email on their own, in your shop's name.

The Today screen with a check-in due: one tap on Text Nadia opens Messages with the text already written, then the app asks whether it went out and takes it off the list.

5 · The books

The books are done when the month is.

Every invoice, payment and receipt you snap lands in the books as it happens. Profit and loss, money owed, sales tax by month, expenses, PDF reports, a tax summary, and one export for your accountant.

No shoebox of receipts and no weekend at the kitchen table. Hand your accountant one export.

The Money screen for October: revenue, what the shop kept, sales tax and unpaid invoices, then the books list, profit and loss, and sales tax by month.

And the rest of the job

The week's schedule: each day's visits with their arrival windows, and which days are open.
Arrival windows, not time slots. Book a time, see the day and the week, and give the customer a window you can keep.
The Your brand screen: the header that goes on every invoice, with the shop's name and initials, and the fields for the name, phone and logo.
Your name on everything. Your logo, colors and shop name on every quote, invoice and report.
The Reports screen in dark mode: profit and loss, receivables, sales tax, sales by customer and by service, expenses, payments and a tax summary.
Reports for tax time. Sales tax, expenses and a tax summary, ready as a PDF with your logo or a spreadsheet.

Real app screens, sample shop.

Your records stay on your phone and in your iCloud

Your customers, their cars, every inspection, quote and invoice, and your books live on your iPhone and in your own iCloud, not on our servers. That's why there's no account to create and nothing stops working in a dead zone.

  • New phone? Sign in with the same Apple ID and everything comes back.
  • No ads, no tracking, no selling your data. We never see your customer list or your books. Read the privacy policy.

Coming

These aren't in the app yet. Some may land after the app does, so we're not putting dates on them.

  • Online quote approval: the customer opens the quote from a text, approves it and pays a deposit.
  • Card payments on your own Stripe account: pay links, deposits and saved cards.
  • Your request page and website form: customers say what's wrong and when they're home.
  • Emails that send themselves: reminders, receipts and check-ins, in your shop's name.
  • Parts ordering in the job, through your parts supplier, on your own account.
  • The bank link, so your bank's transactions come in by themselves. The bank check, from a statement you import, works today.
  • Your website on your own domain, business email, and a garage page for your customers.

Questions

When can I get it?

Soon, and we don't have a date to give you yet. One Wrench Pro is in testing now with a working mobile mechanic, who is also a co-owner, and the App Store is next. Join the launch list and we'll tell you when it's out.

Do I need to create an account?

No. Open the app, put in your business name, logo and colors, and start. Once card payments are live, you'll connect your own Stripe account from the app to take cards.

Do my customers need the app?

No. You send them the report, the quote or the invoice as a PDF, by text. No download, no sign-up. Pages they open from a link are coming.

Does it work without signal?

Yes. Everything is saved on your phone first and syncs to your iCloud when you're back online. Sending a text still needs signal.

Does the app send texts by itself?

iPhone apps can't send texts on their own, so the app writes the text, addresses it and opens it in Messages; you tap Send and it goes from your number. Messages that go out by themselves (reminders, receipts, check-ins) are coming, by email in your shop's name, with replies coming to your email.

Is there an Android version?

Not yet. One Wrench Pro is on iPhone first. Leave your email and we'll tell you when it's on Android.
