Sumwhere Calculator

You worked out the price at the hardware store. A week later you're ready to start that project and it's gone. Sumwhere keeps every result you calculate, along with when and where you worked it out.

It looks and works exactly like the calculator already on your phone. The difference is what happens after you total it up.

Every result is quietly saved with the date, weekday, and time of day. Turn on location and it'll also remember where you were standing, so a number you worked out at the hardware store on a Monday morning or a customer's house on a Thursday afternoon is easy to find again, even weeks later.

All the muscle-memory details of the calculator you already use. Switch to the scientific keypad, and landscape expands it into a familiar wide grid. For those who hate science but still like to remember — memory keys (MC, M+, M-, MR) sit on both keypads, with a clear on-screen indicator showing what they're currently totalling.

Search your history by the numbers, by a date range, weekday, time of day, or by place, with an adjustable radius for when you can't remember exactly where you were. Add tags and notes, pin favorites, and browse everything in a clean, organized list. It turns your calculator into an actual record of your math. You won't brag about it to your friends, but you'll find it incredibly useful when you need it most.

Location, entirely on your terms
Location stamping is off by default. Turn it on only if you want it, and everything stays on your device - nothing is uploaded, no account required, no tracking, no analytics. Apple's own privacy label says it plainly: Data Not Collected.

Made to be customized
Eight accent colors, a choice of standard or scientific as your default keypad, adjustable history retention.

No subscriptions. No in-app purchases. No ads. Just a calculator that remembers the sum and the somewhere.

How much time would you save if you had better access to the math you've already done? Oh, you've already done the math? Good luck remembering it in a week. Download Sumwhere.
