A real complaint on free tip-calculator apps: ads popping up while you're still entering numbers, sometimes three or four before you can finish one calculation. This tool has no ads inside the calculator itself — it's just the fields and the result.
Split bill calculator, any number of people
Enter the subtotal, tax, and tip percent, then the number of people — the total splits evenly, with each person's share and their share of just the tip shown separately.
Tip calculator, no tax option included
Toggle whether the tip is calculated on the subtotal only or the subtotal plus tax — tipping on the pre-tax amount is the more commonly recommended default, but it's a personal choice either way.
How much to tip, worked out instantly
Every field updates the result live as you type — no separate "calculate" button, and no ad standing between you and the number.
