PalabrasaNumeros is an Android app developed by SamuelBrooks.com that allows you to convert letters, words, sentences, and phrases into numbers. This app is ideal for generating hacker-style passwords to strengthen your passwords, or even for writing, sending, or sharing encoded messages with your friends through WhatsApp, email, or SMS.

The app takes up very little space and does not consume data as it works without the internet and quickly encodes any text in number format. PalabrasaNumeros works on any Android device with a system of 4.0 or higher, from high-end smartphones to the most basic ones on the market.

For example, the original text "One summer day, I was at the beach building a sandcastle" would be converted to "0N3 5UMM3R D4Y, 1 W45 4T TH3 B34CH 83U1LD1NG 4 54ND74TL3".

The free version of the app has usage limitations of three times per day, but this limitation can be removed by purchasing the optional membership offered within the app.
