I use Pancake (https://www.pancakeapp.com/ https://www.pancakeapp.com/) for my invoices, expense tracking, proposal/estimate writing, and reporting. They don't offer a native app, but the site is responsive and works well enough on mobile. Pay once and run on your own server. I previously used Toggl for time-tracking, but have been transitioning out of hourly billing and haven't been tracking time for months.
