Hello, first you need to distinguish whether your own APP is for personal use or for commercial purposes. If it is for commercial use, you need to confirm whether there is relevant authorization. If you use content created by others without their permission, you will be suspected of infringement.

As for avoiding infringement, you need to pay attention to the following three aspects:

First of all, you must pay attention to the trademarkability of the App name, formulate a trademark strategy, and register the trademark in a timely manner. Currently, there are many App products, but few actually use trademark rights to protect their apps. Therefore, it is necessary to promptly register a trademark for the corresponding name to avoid disputes and controversies.

Secondly, we need to improve the creativity of the name. In order to prevent their trademarks from entering the public domain, trademark owners should pay attention to their trademarks, add made-up words accordingly, and use descriptive words or fixedly matched words with caution.

Finally, there is the issue of classified registration of the APP trademark. If the trademark owner can fully apply for registration when applying for trademark registration, the corresponding protection of the trademark will inevitably be comprehensive.

If detailed information is given, a more detailed answer can be given.
