Why are these free?
We built FieldDeck to be the best field app for contractors. These browser tools solve real problems — generating a quick invoice, estimating a job, figuring out your markup. They work without any signup because we think useful tools build trust.
They are also built to be private by default: your documents are generated locally in your browser instead of being uploaded to a cloud PDF service. If you need to keep your invoices, estimates, photos, signatures, and job notes organized on your phone — with everything working offline — that's what the FieldDeck app does. But these web tools are yours to use regardless.
