Most time tracking apps forget freelancers exist. Shifttrackr doesn't. Check in → auto-calculate overtime & pay → generate a PDF invoice → share via WhatsApp. All in one mobile app. Custom overtime rules (1.5×, 2×), multiple jobs with different currencies, 5 invoice templates, and 20+ languages; uniquely, app language and invoice language are independent. Free to start. Love to hear from freelancers, shift workers & contractors! 🙏
