About this app

TURN A DAY'S WORK INTO A PAID INVOICE.

HAMMR is the offline-first invoice maker, estimate app and job tracker built for handymen, independent contractors and tradespeople. Clock in at the job site, log the work as it happens, and send a clean invoice PDF before you leave the driveway.

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 phone 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 Gmail, Messages or any app in the Android 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 Google.

Install HAMMR and move from clock-in to invoice without rebuilding the day from memory.

Contractor invoice app and handyman invoice maker, estimate and quote maker, work hours time clock, job log, mileage tracker, material and receipt tracker, client signature capture, PDF invoice generator and CSV export for field service and small trade businesses - all working offline.

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 Google Play > Subscriptions.

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.
