■ Integrated Calculator & One-Tap Bill Splitting: After calculating the total, simply tap the "/2" button (with optional tip settings) to instantly see the amount each person owes. You can customize these splitting options in the settings. ■No data? A cute icon will pop up! ■ Bill Photo & Calculator on the Same Screen: Constantly switching your gaze between the bill and your phone can lead to errors. By displaying the bill and the calculator on the same screen, verifying figures becomes much easier! ■ Supports 4 Groups of 4 Memory Slots: Save calculated amounts into one of the four slots, then tap the sum button to get the grand total. Perfect for scenarios involving splitting costs among multiple people, taking turns paying, or settling up at the end. The interface text changes color to alert you when all four slots are full. ■ Intuitive Calculation Method: It bypasses standard "order of operations" rules (where multiplication/division take precedence over addition/subtraction). Instead, it follows the way people naturally think when splitting a bill: "Add up all the amounts first, then divide by the number of people." The app calculates from left to right: entering "10 + 8 / 2" yields 9, not 14. ■ Reliable and Convenient: ・Works entirely offline—usable even in restaurants with poor signal. ・No registration or login required. ・No ads. ・No personal data collection. ・Supports Dark Mode; large, clear fonts for easy reading.
