Quick Sigma

Enter numbers the way you would on a calculator, and get totals by category, by item, and by day. Quick Sigma is made for anyone who adds up the same kinds of numbers on a calculator, day after day. Whenever you want to see where things stand, tap the ∑ (Totals) key. Subtotals and the grand total are right there. Every entry is saved on its own, so one mistake never means starting over. Just fix that one entry. ■ Made for - Shop owners who total daily sales by department on a calculator - Anyone tracking household spending by category - Anyone who adds up more than money, like miles or inventory ■ How it works Set up three levels once, at the start: Tab (what you're totaling) → Group (category) → Item (breakdown) Example: Household → Food → Vegetables The groups and items you set up become keys on your calculator. From then on, just tap Group → Item → number. Items are optional: for a group without items, you type the number right after choosing the group. Within each tab, entries are recorded by date, so you can keep using the same keys day after day. Choose a tab, and the date is filled in for you. ■ Totals, your way - Switch views: by group, by item, or by date - See sales entered by department, regrouped by product - Total a period (this week, this month, last month, and more) or any dates you pick - See how many entries make up each total ■ Example: splitting the bill You paid for dinner with friends. Are you now going down the receipt again for each person? With Quick Sigma, enter the receipt just once, from top to bottom. Tap ∑, and each person's total is ready. ■ Your data stays on your device Quick Sigma collects no personal information and no usage data. Nothing you enter is ever sent anywhere.
