Sign languages are full languages with their own grammar, and most countries have their own, so the first step is choosing the right one. This starts with fingerspelling and everyday signs, adds a class with a real teacher, and looks for Deaf community events early, because a language learned only from videos stays one-directional.
Free on any plan. You will see this list again in the app, and nothing is created until you press install.
With a fluent signer, not just an app.
The one used where I live, and a real teacher.
Reading signing as well as producing it.
Log classes and practice. Time spent watching fluent signers counts too; reading signing is half of the language.
Sign languages have their own grammar, and facial expression is part of it. Most countries have their own: ASL, BSL and Auslan are different languages.
Apps teach vocabulary. Conversation needs other people, which is why a teacher and a community event are dated early rather than saved for when I feel ready.
Daily practice that is actually tracked, and a date by which you have to speak to somebody.
A course to follow and a project that proves you actually learned it.
One language, one project, and a routine that survives the month where nothing makes sense.
A number for the year, a routine that reaches it, and permission to abandon a book.
It takes one press. Everything it creates is tagged, so if it turns out not to suit you, it is easy to find and remove together.
