This universal version works with both iPhone and iPad. The iPad version features a full sized (1:1) keypad with TypeTone, a unique audio aid to help guide your finger back to the center of a key.

Going out with friends is supposed to be fun. Splitting the bill afterwards isn't. SplitRick fixes that. Someone covered the Uber? Someone else grabbed dinner? The drinks went on a third card? By the time you're home, nobody really remembers who paid for what, and bringing it up tomorrow feels weird, so you don't. The next time someone covers a tab, drop it into your SplitRick group. Pick who paid, who's involved, and how it splits. SplitRick does the math in the background and updates everyone's balance the second you save so the number you see is the number you actually owe. Or are owed. No spreadsheet. No screenshots of receipts in the group chat. No "wait, was that with tip?" Groups can be anything: roommates, trips, weekly dinners, the bachelorette weekend, the carpool, the parents at your kid's summer camp. Add expenses as they happen, edit them when something's wrong, settle up I the app when you're square. Live balances mean nobody has to remember anything; they just have to glance. Each group keeps its own running summary. Where the money went, by category, when, and by person. We built SplitRick because we wanted something that fits the natural rhythm of going out with people you actually like. Tell the waiter one check, leave the math to us! Upgrade with SplitRick Divide to make the splitting even easier - no ads and a simple photo snap of a receipt to automatically divide items! Terms of Use (EULA): https://splitrick.click/terms
