Is it good?

Well, as a top-performing app with an overall rating of 4.00 from 35 votes cast, I can safely confirm that It's good and worth trying. Here is what people say about Delta Chat:

Bagus dan sangat membantu, hanya saja belum di lengkapi dengan Kemampuan untuk menelepon. yes it's able to make phone call also video call, and I think this App more Easy than Zoom because base on chat/message and more powerfully than other message/chat app with phone number base because if we loose the phone number we will not loose our contact (at least we must re register) or miss contact if that phone number was owned by other. this app look like we have and doing messaging using e-mail but more simple, after we install JItsi meet its aoutomatic integrated with this app The one greatest is now we have WIFI only gadget as powerful as gadget with Sim card as long as we have internet connection. so I have powerful App for communication and data share with worry-free, i hope this app will be massive user and i will starting from my family member. I have a sense if this app (or similarity) will become an officially app as personal ID (look like Line App in Japan but for me Line App look like junk because to many add). good job keep make it easy, clean from add like telegram. I wish you luck.
Update, you clearly said initial few messages could be not encrypted. My mistake. 5 star. Here is why I am still concerned about private while using this app. In DeltaChat: The “MY ORIGINAL MESSAGE” message you sent was displayed on the screen of the recipient. This is no guarantee the content was read. Perhaps it should be "“Encrypted message” everywhere? And I can see some EMAILs with original message (not encrypted) in the header section. e.g. "Chat: SOME MESSAGE.". I am sure it is a small bug and will be fixed soon.

Download Delta Chat APK for Android and install

I would love to guide you on how to download and install Delta Chat APK for Android in just five simple steps. But first lets have some basic knowledge of APK files. Android Package Kit is an Android application package file format used for distributing files and installing them on Android OS devices. Installing apps and games from APK file is a simple and straightforward process which you will remember forever when done once. It is a safe and working way to avoid restrictions made by developers for distributing apps in some geographical regions.

Step 1: Download Delta Chat APK on your Android device

Tap the blue button below and navigate to the download page. There you will choose the available download method.

Step 2: Choose the download method

Have in mind that some apps and games may not be available in Google Play for your country of residence. You can choose to save the APK file from Android Freeware mirrors instead of downloading the software from the Play Store. We are proud to serve your working mirrors 99.9% of the time.

Step 3: Allow installation of third party apps.

If you get an installation warning after starting the saved file, click Menu > Settings > Security > and check Unknown Sources to allow installations from this source! This has to be done only the first time you are installing an unknown APK file.

Step 4: Find and install the downloaded APK file

I suggest using a file manager app (MiXPlorer is my choice as robust and easy to use) to locate Delta Chat apk file. It is most commonly located in the Downloads folder. Open it now and proceed to installation (check out this How to Download and Install APK and XAPK files guide if you experience difficulties).

Step 5: Launch the app and enjoy

Start the installed Delta Chat app and enjoy it!

Is It safe?

I strongly recommend Delta Chat as good communication software. With over 105k+ and counting downloads, it is a safe app to download, install, and share with friends.

Note that the APK file can run on every popular android emulator.
