Love the focus on simplicity here - time tracking shouldn't require a PhD. Key insight for makers: time data becomes valuable when connected to income/revenue goals. Consider building integrations that sync tracked hours to Stripe invoices automatically, or dashboards showing income per hour by project type. This transforms time tracking from busywork into actionable business intelligence. Also, think about API access for power users - some of us want to build custom dashboards or pull data into our analytics stack. The earning visibility piece could be a real differentiator for freelancers.
