Have you heard of the free app Amikumu? It’s available for Android and iOS, and lets you search for other users closest to you geographically that have included the same language in their profile.
For example, if you say in your profile that you’re learning Manx or Cornish or Dutch (and you can show whether you are a beginner, intermediate, advanced, or native speaker), then you can search for people located near you that also speak or are learning Manx or Cornish or Dutch. Amikumu will give you a list of the closest 100 users! You can then text them a message, and if you get on well with them, arrange to meet in person or online for a chat.
Amikumu also released a new feature recently that lets you send out a public message to the 100 people closest to you geographically. It’s a great way for letting people know of any events or conversation groups in the desired language in your area, and you can find out what others are posting too.
Amikumu has over 7,000 languages included in its database, and several of them can also be used as the language of the interface. They’re keen to translate the interface and their website into as many languages as possible if anyone has any free time and fancies volunteering to give them a hand.
