My Tip Calculator: Free tip calculator for bills and split payments

My Tip Calculator is a focused utility that solves a persistent social friction point: the dinner table math. While most modern smartphones have built-in calculators, this tool optimizes the specific workflow of tipping and splitting. It strips away the friction of account creation and server round-trips, providing an instant, reactive interface that updates totals as the user inputs data. From a product perspective, the strength lies in its restraint. By processing all calculations in the browser, the developer has eliminated latency and privacy concerns, transforming a simple math problem into a trust-centric tool. The inclusion of a tipping guide and service-specific presets adds a layer of contextual value that goes beyond a basic multiplication script, making it useful for travelers unfamiliar with local customs. However, the simplicity is also its ceiling. In a crowded field of 'single-purpose' web apps, the tool offers little beyond what a few lines of JavaScript can do. The 'universal currency' claim is technically true only because the app ignores currency symbols entirely—it treats all inputs as raw floats—which is practical but technically trivial. This is a solid, no-nonsense tool for users who want a dedicated interface for bill splitting without the bloat of a full finance app. It is an example of 'small software' done correctly: it does one thing, does it fast, and doesn't ask for your email address.
