About
TURN A DAY'S WORK INTO A PAID INVOICE.
HAMMR is the offline-first job tracker, time clock, estimate and invoice maker built for independent contractors, handymen and tradespeople. Clock in at the job site, log the work as it happens, and send a clean PDF before you leave.
FROM CLOCK-IN TO PAYMENT
- Start a live timer for each job and see hours and earnings as you work.
- Log mileage, materials, receipts, notes and site photos in one job record.
- Pin your location at clock-in and capture a client's on-site signature.
- Keep working without a signal. HAMMR saves everything on your device first.
ESTIMATES AND INVOICES
- Create a professional estimate before the work starts.
- Mark it approved or declined, then convert an approved estimate into an invoice.
- Build invoice line items from labor, mileage and materials, or add custom charges.
- Apply tax and flat discounts, set due dates and generate a polished PDF.
- Share estimates and invoices through Mail, Messages or any app in the iOS share sheet.
KNOW WHAT IS PAID - AND WHAT IS NOT
- Record deposits and partial payments while HAMMR tracks the remaining balance.
- See collected revenue, outstanding invoices, overdue balances and unbilled work.
- Add Venmo, PayPal or Cash App payment links and QR codes, plus Zelle or check details.
- HAMMR never processes your client's payment, so it adds no payment gateway fee.
READY FOR TAX TIME
- Review tax collected, material spend and month-to-date or all-time totals.
- Export a clean CSV for your accountant.
- Export a PDF bundle of invoices, including signed copies.
BUILT FOR INDEPENDENT TRADES
HAMMR fits handymen, plumbers, electricians, painters, landscapers, carpenters and other solo contractors who need a simple field tool - not a heavy office system.
YOUR WORK, YOUR DATA
Core job tracking, invoicing and exports work on-device. Create a full JSON backup whenever you need it. HAMMR Pro adds optional cloud backup and multi-device sync after you sign in with Apple or Google.
Download HAMMR and move from clock-in to invoice without rebuilding the day from memory.
HAMMR Pro is available as a monthly auto-renewing subscription or lifetime purchase. Pricing is shown before purchase. The monthly subscription renews unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your Apple ID settings.
HAMMR is a record-keeping tool, not accounting, tax, legal or payment-processing advice. You are responsible for the records and payment details you create.
