Sumptus — Latin, noun. Expense; expenditure; the cost of things.
Who we are
Sumptus Studios, LLC is a tiny independent software company with deep roots. Our founder shipped the original ExpensePlus on the Apple Newton MessagePad in 1995, then on Palm OS, and watched the same app earn its place on the home screens of business travelers around the world.
Three decades later, we’re back — same obsession with the details, modern frameworks, and a renewed focus on the device you actually carry. We build for iOS first, we build for the long haul, and we build the apps we wished existed.
What we make
One app shipping now, more in the works.
The direct descendant of ExpensePlus for Newton and ExpensePlus for Palm — rebuilt from the ground up for iPhone and iPad. AI receipt scanning, bank import, custom Excel export, and the same thoughtful interface our customers have trusted for thirty years.
