20% Tip Calculator

I made 20% because I wanted a tip calculator that gets out of your way — the keyboard's already up when you open it, and the math is done before you'd have finished unlocking a bigger app. • PRESETS: 15, 20, 22, 25, and 30% built right into the keyboard. Tap one and you're done — it remembers your last pick for next time. • SPLIT: Divide the bill any number of ways and see exactly what each person owes. • ROUND UP: Round the tip or the total to a whole dollar, so nobody's counting out exact change. • WORK BACKWARDS: Know what you want to pay? Type the tip or total and the percentage figures itself out. • 100% FREE: No in-app purchases, no subscriptions, no ads, and I'm not planning to add any. I'm not trying to make money off this — I just wanted the math to be one tap, not five. Comes in dark and light, works fine for a quick trip to another country too. Fully on-device — no account, no tracking, no network calls. If there's something you want it to do, let me know in a review.
