North America is unique on planet earth as it adds sales tax to prices at checkout.

After sales tax, in places like restaurants, bars or hair salons, it is up to someones discretion to tip for the service - often 20% of the total price after the added sales tax.

This experience is confusing for students, immigrants and tourists visiting North America, who often complain about having to do the mental math to calculate the true price of something.

To solve for this problem, we created Price After - a mixed reality, AI powered application that aims to let you know the maximum amount you could end up paying for something before you check out. Simply point your camera at the price on any product or website and Price After will reveal the maximum cost.

As taxes vary wildly across the US and Canada and are subject to change, with rules and exceptions being for all different kinds of products; Price After simplifies the calculation to show you the maximum price that you might pay for any item in a given state, province or territory.

Price After also includes resources to let you learn about how sales tax works in each state, province or territory as well as a guide for tipping in North America.

The app is available in English and Spanish was launched to the Google Play Store and the Apple App Store in May 2023.

Price After does not track any analytics and is available on Android 11.0+ and iOS 14.0+.

The app was initially released as Marked Price, but was renamed to Price After thanks to Weston Rivell.

The app was designed by Oscar de la Hera Gomez who was also solely responsible for the development of all the releases with the exception of the Calculator, which was developed by Gonzalo Cachón under Oscar's direction.
