CalcKit: BMI, Tip & Units

CalcKit brings three everyday calculators together in one clean, ad-free app. No account required, no data leaves your device. BMI CALCULATOR Enter your height and weight, and get your Body Mass Index instantly on a color-coded gauge. Save entries to build a personal history — stored locally on your device, never sent to a server. TIP CALCULATOR Figure out the tip or gratuity and split any bill in seconds. Tap a quick-select preset (10 %, 15 %, 20 %, 25 %) or fine-tune with the slider. Splitting between more than two people is available with CalcKit Pro. UNIT CONVERTER Convert across 60+ units in eight categories: length, weight, temperature, volume, area, speed, time, and currency. Results update live as you type. Pull down to refresh exchange rates — or let the app handle it automatically.
