Prime Numbers is a free Android application developed by Fernando Gozalo, falling under the category of Education & Reference. This app is designed to cater to the needs of people interested in prime numbers, especially students, pupils, and high-educated people.

The app offers three main features: firstly, it allows users to view a list of prime numbers. Secondly, it highlights prime numbers among all natural numbers from 1 to 10,000. Thirdly, it helps users check whether a given number is prime and also find all its divisors.

The app is user-friendly and easy to navigate. The interface is simple and straightforward, making it easy for users to use the app without any complications. The app's highlight feature is particularly useful for students who are learning about prime numbers.

However, the app lacks some advanced features that could make it more useful for advanced mathematicians. Additionally, the developer's contact information is prominently displayed within the app, which may be off-putting for some users.

Overall, Prime Numbers is a useful app for anyone interested in the topic of prime numbers. Its simplicity and ease-of-use make it an excellent choice for students and pupils.
