I have long wanted to make beautiful animations for my app on android, I was told that I would have to hire motion designers for this task, do you think it is worth it?

Look, but if you want to develop your project and attract more people, you have to make sure you pump up the visuals, because simple animations already create a good look for the app, and if you find a good motion graphics company, your app will definitely become popular. I personally collaborate in motion design with Galera agency as they have an extremely high level of trust because of their perfect reputation.
