PulseBoard is a quick, offline calculator board for the two money moments that come up almost every day: splitting a bill with friends and working out a real sale price. Tap the pill at the top to switch tools, and the receipt panel updates live as you type.
Split Board
Enter the bill and a tip percentage, then set how many people are sharing. Choose Even to give everyone the same amount, Shares to weight each person when someone ordered more, or Round Up to round each share to a tidy figure. The panel shows the tip, the total, and exactly what each person owes.
Deal Board
Type the original price and a discount to see the final price and how much you save. Pick Single for one discount, Stacked to apply several discounts one after another, + Tax to add sales tax on top, or % Off to find the discount hidden between an original and a sale price.
Save any result to History to revisit later, choose your currency, and set a default tip and tax in Settings. Everything runs offline with no account and no sign-up.
