You Need to Be Actively Using the Language

If you're just using an ap, whatever that ap may be, i don't know if you're really doing your language justice. You need to be interacting with people, talking to them and trying to maintain some level of conversation. It's a lot harder to be facing someone on sume call and trying to talk to them and feeling exhausted at the end of the lesson. That doesn't give you that same positive sense of achievement that you do from clicking a few buttons on a nap. it's harder, but it's something that consistently makes you actively using the language and actively improving your language skills.
