F The Hours is a web app for UK freelancers and sole traders that combines time tracking, invoicing, expenses and a UK tax estimate. Time is logged by client, project and task type, with a grouped or flat view, filters, search and one-click export. Invoices are branded PDFs generated from logged hours, with invoice numbering and draft, sent, paid and overdue states, downloadable or emailed to the client. The tax page gives a running estimate for the chosen tax year using UK income tax bands, Class 4 and Class 2 National Insurance, student loan plans and payments on account, plus a take-home pay calculator for employed or self-employed income. Income and expenses are mapped to the SA103 box numbers with a readiness score and a spreadsheet export to copy into the return on gov.uk; the app does not file to HMRC. Expenses use HMRC categories, mileage is recorded at the approved rates, and home office allowances are included. Data is encrypted in transit and at rest, stored in the UK, expor
