Square Avatar is a free Android app developed by Braintrapp in the Lifestyle category. It allows users to create custom avatars and memes with ease. The app provides various features to dress up your avatar and add text in different fonts and colors. The free version has ads and can save only half-resolution pictures in JPG format. However, the pro version offers full-resolution pictures in JPG, PNG, and transparent background PNG that can be used in further applications.

Users can save and load their avatars in the pro version and share them with friends via QR code. The app also lets users add their details and use it as a business card embedded in the QR code. Additionally, users can scan QR codes of avatars created by others and modify them by changing the text. The app offers more than a dozen font types to choose from and customize the text as per the user's preference.

Overall, Square Avatar is an excellent app for creating custom avatars and memes. However, if you want to save full-resolution pictures or use transparent background PNG, the pro version is the way to go. If you encounter any issues or have suggestions, the developer can be reached through email.
