Hourledger is a billable-hours tracker built for freelancers, consultants, and lawyers who invoice by the hour — fast, fully offline, and with zero account required. Start a timer with one tap, and Hourledger automatically rounds your billed time to the increment your invoices actually use. Most time trackers round however they feel like it, or don't round at all, leaving you to redo the math before every invoice. Hourledger defaults to 6-minute (0.1 hr) increments, the standard for professional billing, and always rounds up so real work is never shortchanged. Why Hourledger: • One tap starts the clock — no project wizard, no cloud sync delay • Automatic billing-increment rounding (6 / 10 / 15 / 30 min, or exact) • Clean totals for Today, Week, and Month, per client • CSV export ready for your invoicing software • 100% offline — no account, no tracking, no ads Hourledger Pro (one-time unlock): • Unlimited clients and projects • Polished PDF invoice export, ready to send • Yours forever — no subscription Built for people who bill their time and want to spend less of it on paperwork.
