Experience

Sygic Travel Maps Offline

One of the best personal helpers for travelers (and in my opinion the best one), Sygic Travel brings planning to a new level. It helps to plan a user's trip by exploring the area around the user including showing 360° videos inside the application–all built natively for the iOS platform. The application also supports booking hotels, tours, and activities by third-party services.

Sygic Travel Apple TV

This is an Apple TV application with support for 360° videos and a sign-in for Sygic Travel iOS users to synchronize a user's favorited items.

Sygic Travel Apple Watch

Use this Apple Watch app to quickly access your itinerary, your favorite places, and other useful places around you (such as restaurants or public transport stops). For each place, you can view additional information such as a description of the place or its opening hours.

ProMenu | Nájdi si svoje jedlo

This is the application for a local restaurant's daily menu. It has a simple and intuitive UI for all kinds of users with the ability to search restaurants on a map or in a list.
