Masume

You already know the trick. Open a spreadsheet, type numbers down a column, let it add them up. It works for everything: a shopping list, a trip, the real cost of your fixed monthly bills. It just does not work on a phone. You pinch to find the cell. You fight the keyboard. You write =SUM() one more time. By the time the sheet is ready, the moment has passed. Masume is that column of numbers, and nothing else, built for a phone. HOW IT WORKS Name a sheet. Put plus and minus numbers in it. The total is always on screen while you type. There is no formula to write, because there is only one thing this app ever does: add the column up. Rows are rows. Tap one and the keypad is already there, with plus and minus where your thumb is. Flip the sign, move to the next row, keep going. The figures line up in a column, so your eye can run down them the way it does on graph paper. WHAT IT IS NOT Masume is not a budgeting app. There are no categories, no budgets, no monthly reports, no charts. Nothing to set up before you can use it. If you want those, you want a different app, and that is fine. WHAT IT IS FOR - Totalling a basket before you reach the register - Splitting a trip: who paid for what, added up on the spot - Listing fixed monthly costs to see the number you actually pay - Any temporary money in and out: a move, a wedding, a side project FEATURES - A keypad with plus and minus. Flip the sign and move straight to the next row - A short note on any row - The total stays on screen while you type - Deleted sheets rest in the trash for 30 days, so a mistake is not final - A Home Screen widget for a sheet total, including Lock Screen sizes - Dark and light, row spacing, currency and display language are all yours to pick - Eight languages: English, Japanese, Simplified and Traditional Chinese, Korean, Spanish, French, German PRIVACY There is not one line of networking code in this app. No third-party libraries. No analytics, no advertising, no tracking. What you type stays on your device. MASUME PREMIUM — ONE PURCHASE, NO SUBSCRIPTION The free app gives you 5 sheets and 15 rows per sheet.
