Text Counter is an Android app developed by Maksim Gusev that allows you to quickly count the number of characters (with and without spaces), words, letters, and symbols in your text. The app also calculates the number of "water" words, which are those that do not carry any meaning, and "toxic" words, which are keywords that can harm your text's SEO. Additionally, the app identifies "mixed" words, which are words composed of letters from different languages and often used by copywriters to deceive search engines.

The app's interface is straightforward and easy to use, making it accessible to anyone who needs to count the number of words or characters in their text. The app is free to use, but users can upgrade to the PRO version to disable ads.
