If you own a smartphone, tablet, or phablet, you can use Google Play (formerly Android Market) there to download some great apps for to help you with your Spanish.
I have an Android smartphone and have just downloaded two of the best Android apps for Spanish out there. One of them is the Spanish Dictionary RAE, made available for Android phones by STK Developers. If you have been studying Spanish for a while, you probably know what RAE is: Real Academia Española, or the Royal Spanish Academy, the institution that regulates the usage of Spanish since the early 18th century.
Well, the Spanish Dictionary RAE comes not only with a whole bunch of words (from the whole Hispanic world!) and great dictionary entries, but also with verb conjugations. So if you're unsure how to use a verb and know a little grammar, you can quickly check there.
Another one of my favorite apps for learning Spanish is iTranslate. This one is the most popular translating tools out there for any language, and there's a version for iPhones as well. In fact, as its name suggests, it started as an iPhone app first.
iTranslate facilitates interaction with natives to an incredible degree, as it not only helps you translate sentences from English to Spanish and 50+ other languages (it has Romanian as well), but also helps you speak the words -- or let your mobile device do it for you, to help you communicate with native speakers.
Now, the translations are not always spot-on, but that's to be expected. I don't understand why they translated "I'd like a glass of water" (English) to "I'd like a bottle of water" (Romanian), since the word "glass" can never mean "bottle" in Romanian. Also, Romanian doesn't come with the audio feature.
Among the best iPhone apps for learning Spanish, I'm reading Duolingo is one of the most popular. Just like the Spanish Dictionary RAE and iTranslate, this app, too, is free. I'm reading on the iTunes App Store that PC Magazine gave it PC Magazine Editors' Choice for Language Learning, with the blurb: "Among free iPhone apps for learning or practicing a language, you can't beat Duolingo."
So check out Android or iPhone apps if you want to improve your conversational Spanish. They're free and they're fun, and they help a lot when you're traveling. In fact, some apps are designed with travel in mind, so you'll get the content of phrasebooks in an easy-to-navigate format. One of them is Learn Spanish Phrasebook by Codegent. It only includes some 800 words and phrases, but it can be helpful. Another one is the app from busuu.com (called Learn Spanish with busuu.com), which is actually a combination of phrasebook and vocabulary (the latter organized by categories and themes).
