Telegram is a messaging phone app that is all about features while focusing on privacy. The cross-platform app continues to grow in popularity as it uses end-to-end encryption of your messages over cloud-based distribution architecture. So, simply put, it's never keeping track of what you are sending or receiving.
It is all about privacy with secret chats that have self-destruct timers so you can control hidden conversations and keep them secure. Other features include the ability to share large media files and the ability to use the web version that works with most browsers. The "unsend" button is also nice, allowing you to get your message back or delete it within 48 hours.
Similar to other messaging services, interactive stickers are available and a good way to express yourself. Unfortunately, video calling isn't supported, but if you are looking for an app with a simple interface while still being fun and interactive, this free downloadable app may be just what you need.
