Bonjour, Hola, Ciao, Hallo, Konnichiwa, Namaste...well you get the idea!
Duolingo is widely regarded as the world's number one language learning app. It's available on the App stores ( Apple, Google )and also online. They also have podcasts.
I've used it myself ( the basic version) and found it be very simple, helpful and fun. It's definitely worth a try if you're interested in learning a new language.
There is a a very wide selection of languages offered and includes all the major languages plus a few more niche ones like Esperanto, High Valyrian (GoT) and Klingon ( Star Trek) !
It also has league tables in case you're competitive like me
Normally users can get the ad free (premium) version for just 2 weeks...this is exceptional value as you can use Duolingo for 3 whole months with no fee. Just remember to cancel in good time if you don't want to continue your subscription, which is £12.49 if renewing monthly.
