Download the app from AppStore. If you use iTunes, sync it with your device. The first step of the actual installation is just like installing most other iPhone or iPad products.

It starts with the welcome message, which lets you know that you’re about to use our application. Touching OK will lead you to the Settings page.

Wait a second or two until the busy icon disappears from the status bar. Sleek Tip Calculator needs to load all of application data from your iPhone and has to look at your network connections to let you write online reviews and see maps.

Tip rates

Tap the number you want to change. The keyboard will pop up. Give a new rate (like 12.50) and touch Done to finish editing or tap the next number you want to change.

Invalid data is set to 0.00. Custom tip amount can override these settings on the main screen.

Tax rate

Sales tax is supported. Tap the number and set the value on the popup keyboard (like 6.5). Touch Done.

Valid data is limited to 50.00 %.

Tax method

Enable it to set our algorithm to bill amount includes sales tax. In this case you tip on the entire check. Most of us tip this way, so the default value is enabled.

Many of us feel strongly about tipping on the tax. “The tax has nothing to do with the service of the wait staff, runners or kitchen. And it varies from county to county and state to state. To equalize I just ignore the tax and tip on the subtotal.”

Disable this variable to let us calculate with the bill amount before sales tax.

Round up/down option

Total rounds up to the nearest dollar when enabled. Set to OFF to get exact sums.

Split limit

Set the maximum value of sliders here.

Default is value 10. Upper limit is 100. Sliders are practically unusable above 20. On the main screen, when you do not want to use sliders, tap on editable text box to set the exact value.

Sound effects

Sound effects can be muted. Disable it if you do not want our app to say a … beep.

Skins

Sleek Tip Calculator has multiple application background choices from sleek to geeky, from London’s pubs to New Zealand’s golf club.

Select your favourite colors and schemes by touching the row. Tap the Calculator icon on the bottom bar to go to the Calculator page and see changes.

Please be patient while Settings screen is loading. Older gadgets need 2-3 seconds to find all the items our setup page is searching for.

Calculating splits

5. The calculation of the total sum is based on these settings: bill amount, tax inc/exl method, tax rate, tip and round up of total option. When round-up option is enabled the tip is adjusted.
