WrenchStrike

WrenchStrike is an invoicing and estimating app built for mobile mechanics and one-person auto repair shops. It runs a job from first quote to final payment: write an estimate, get the customer's signature approval right on your phone, convert it to an invoice, and record how you got paid.

Key features:

• Estimates lock after customer approval, with a finger signature (or "approved by phone") printed on the invoice
• Sent tracking with a follow-up reminder for estimates the customer hasn't answered
• Professional PDF invoices with your shop name and logo, sent by text or email in one tap
• VIN scanner that fills in year, make and model
• Saved line-item library so common jobs and parts take seconds to add
• Parts tax and discount handling
• Payment tracking for cash, Venmo, Cash App, Zelle, card and check, including partial payments
• Schedule C profit view for tax time, by year
• Miles or kilometers, with dates and currency following your region
• iCloud backup with dated snapshots and restore
• Face ID app lock, light and dark themes, in-app chat support

Everything is stored on your device and your own iCloud. No account to create, no login. First 5 jobs are free. WrenchStrike Pro removes the job limit for $5.99/month or $55.99/year.
