ODDcase Blackjack AppAlthough it can be overwhelming to slog through the tens of thousands of smartphone apps available to eager travelers, those who take the time to download a few key ones can enhance a Las Vegas vacation.

Whether you're looking for general information, insight on particular resorts or activity-specific assistance, in Vegas, there's an app for that.

General Las Vegas travel advice

With myriad restaurants, nightclubs, shows, shopping opportunities and activities to choose from, the problem isn't determining whether there is something to do or see or eat but rather what to choose from all of the options.

A number of Las Vegas-specific apps offer ratings and review systems from other users, and those with the most reviews often have the most comprehensive overview of any particular Las Vegas attraction or resort.

TravelVegas is particularly popular and enables users to search in a variety of verticals, depending on if they are looking for a certain kind of activity or they want something to do or eat at a particular resort.

Venetian Palazzo AppVegas Mate is also a popular general travel app for the city. In addition to offering ratings and detailed information regarding amenities, attractions and features of particular resorts, Vegas Mate has relevant information not found on other apps, such as a listing of resort fees, finding the top suites, information for travelers on getting around, conventions, gambling and more. Under the tourist tips section, there is info on how to tip, where to find medical attention, things to do for those under 21, etc.

Additionally, a news feed pulls in the latest updates and weather from around the city, and a trip planner helps keep all those show tickets, dinner reservations and hotel bookings in order.

Vegas Indoor Maps has a comprehensive collection of resort interiors and the Las Vegas Strip. Though the interface is a bit clunky, casino floors can be overwhelming, and this app can help visitors orient themselves with their surroundings. Additionally, a map of the properties on Las Vegas Boulevard helps familiarize visitors with the larger picture of how resorts are laid out on the Las Vegas Strip.

Yelp and FourSquare, though not specific to Las Vegas, are handy additions on a smart device, as checking in at restaurants and lounges in particular might net additional deals and discounts.

Resort-specific apps

By now, most Las Vegas casino hotels and resorts have their own apps. Each MGM property has its own app, mirroring that resort's website in a way with information on shows, attractions, spas and restaurants. Some of the apps (such as the Aria) offer virtual tours of the rooms while others (like the app for Luxor) have much simpler listings.

MGM Resorts' new WiFi system includes interactive resort maps for the company's apps, beginning with the Bellagio. Future plans include adding the feature to other property apps. This location-based map has point-by-point directions to nearby restaurants, stores, rest rooms and more.

Nobu AppA new wine menu app enables guests to read reviews about wines, rate beverages and email wine labels to themselves so they won't forget a vintage they've particularly enjoyed.

Members of MGM Resorts' M Life, the company's rewards program, may want to download the app made specifically to track points.

A minimal number of Caesars properties have stand-alone apps, and the company hopes to launch an app for its properties and members by the end of the year.

The Venetian and the Palazzo share an app, and the Grazie Loyalty Program is built into it. Wynn has added features such as short video clips from its show, "Le Reve," its nightclubs and a couple of the resort's bars.

Caesars' newest boutique hotel, Nobu, also has its own app, which provides information about the general amenities as well as features of Caesars Palace.

Apps that enhance a visit

TripAdvisor Las Vegas City Guides AppBeyond general Las Vegas or resort-specific apps, there are other smart device features that can enhance a trip to the city. For those who want to perfect their casino skills, ODDcase Blackjack comes highly recommended as a training tool for blackjack. There are several customized games to choose from, and instruction comes in the form of a dealer who advises when the user has made a bad play. Though there are several poker apps, Zynga makes one of the better ones for those who want to learn how to play the perfect hand.

To explore all that Las Vegas has to offer, consider downloading either the Las Vegas City Walk app or the TripAdvisor City Guide for Vegas, both of which offer themed walking tours (such as family fun; architecture and art; shopping; and wedding chapels, among others), primarily on the Strip.

Night owls should download VelvetRope, which details all things related to Las Vegas nightlife. Due to partnerships with nightlife venues, the creators of this app are able to provide updated entertainment details as well as provide users with direct access to guest lists and table reservations.
