Text messaging is still a very popular way to stay connected with friends and family. And while Android comes with a built-in SMS app, it’s usually Google’s app, which may not be to everyone’s liking.

Fortunately, there are many secure, open source apps that you can choose from instead. Here is a list of the top six free and open source text messaging apps for Android.

1. Signal Private Messenger.

Signal Private Messenger is one of the most popular open source mobile messenger apps for Android. Also, it’s completely free, so this is a great option if you want an app that doesn’t charge for texting.

The app supports one-on-one chat, group chats, photo attachments, voice calls and video calls. It includes all the other bells and whistles you’d expect from an app: themes, emojis, reading receipts, and more.

The signal is completely open source, peer-reviewed, and not affiliated with any major tech company. Best of all, it allows you to communicate securely on the Internet with a robust end-to-end encryption protocol. This means that no one can read your messages or view your conversations except the people you are talking to.

Where you go, what you do, who you talk to on the signal is your business, not yours. But how does the app help keep your communications secure? Here’s how the signal works.

QKSMS is a user-friendly, instant messaging app for Android. The app supports SMS, MMS, group chats (with group media support), and end-to-end encrypted chats with data protection.

The free app is open source and has no ads or hidden features that may compromise your privacy.

QKSMS is unique in that it allows you to track all messages you send to ensure they are delivered correctly. You can also back up your messages if something happens to your phone, so nothing is lost.

In addition, the app lets you schedule messages so that they go out at a default time or on a specific day. This makes it a great choice for sending birthday messages.

3. ویکر می.

Vicker Me is a privacy-based app for secret text messaging, video calling, and file sharing. The free app is open source, so you have nothing to hide.

There are no ads or hidden features in the messaging platform that spy on you for money. It also does not rely on a central server to store your messages, and it never keeps them permanent.

The curve includes an end-to-end encrypted “secret chats” feature. It does not require a phone number or email address at the time of registration.

The SMS app includes a self-district timer for sent messages, meaning no one can read your messages, and you can use the app to send messages to a group of contacts at the same time.

Plus SMS is one of the best free sms scheduler apps for android. This allows you to schedule your messages for later dates.

Messages are all stored in one place where you can easily arrange them in a conversation by contact or topic so that you always know where to go when you want to retrieve a particular message.

The app is fully integrated with Google Voice, which lets you send text messages from your email or phone number using Gmail. Even if that person is not available at the moment, you can choose a phone call instead of an SMS.

The messaging and collaboration app allows you to manage projects more efficiently. You can use them to securely share files while talking about them in real time via voice calls or screen share. So, if you are looking for a free WhatsApp alternative, Element can be a great choice.
