About this app

Perday is an offline-first work-logging and invoicing app for freelancers — log daily work hours, track payments, and generate professional PDF invoices, all on your device. Whether you bill by the hour, by the shift, or by the project, Perday keeps your work and money in one simple place — and it all lives on your device, always private. Log work in seconds. Tap a project, log your hours or shifts, and watch your month fill in on the calendar. Set your rate once and Perday does the math. Three ways to bill. Hourly, per-shift, or fixed-package projects — each with its own progress and balance, so you always know what's been paid and what's still owed. When a project's done, mark it fully paid to tidy it away without losing the numbers. Invoices that look professional. Pick a clean template, add your branding and colours, and share a polished PDF in a tap. Payments and taxes, sorted. Track every payment against every invoice. See what's outstanding at a glance, and export a tidy Excel pack — summary, invoices, receipts and work logs — ready to hand to your accountant at tax time. India users get TDS and GST tracking; everyone else gets their own tax setup. Private by design. Your income, clients, and invoices never leave your device. No ads. No tracking. No data selling. Lock it all behind a PIN, and back up anytime — no cloud account required. Free to use, with a free trial of Premium. No card required, and no automatic charge when the trial ends.

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
