Inside HAMMR

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

Time, mileage, materials, receipts, site photos and the client’s on-site signature all live in one job record. Everything is saved to the device first, so a weak signal never stops the workday. HAMMR Pro adds optional cloud backup and multi-device sync after you sign in with Apple or Google.

Privacy & data handling How HAMMR treats the data you put into it
  • HAMMR is offline-first: jobs, clients, hours, mileage, materials, photos, signatures, invoices and estimates are stored locally on your device by default.
  • Nothing leaves the device unless you sign in and turn on Cloud Sync (a HAMMR Pro feature), or you export or share something yourself.
  • GPS is used only at the moment you clock in, and only if you enable it. Camera and photo library access is requested only for the specific receipt or job-site photo you choose.
  • We do not show ads, use advertising SDKs, or sell your data. Full details are in the HAMMR Privacy Policy.
