Edit 2/25/2023 - The developer decided getting the app into the Play Store alpha program was too complex and will be providing an APK for download.


An Android app capable of displaying images from the tCam cameras is ready for some alpha testing.   If you're interested please reach out to me with that, either in a message here on, or to my personal email address which you can find at my website or via my github page.  I'll get you on the list.  When the developer is ready he or I will notify you when it's ready to download and include instructions how to do that and how to provide feedback.

Initial limitations

The app is pretty full featured however it has a known issue when streaming.  The streaming stutters.  The developer knows about this and plans to rewrite the socket handling code to deal with this.  Other than that please submit feedback about other issues or features.

TL;DR about the Android App

People have asked for an Android App since tCam-Mini was first released and I don't blame them.  Lots of Android phones out there.  If you've ready back you might see that I originally wanted to use Xojo to take the iOS app I developed last year and release a version for Android when Xojo finally supported sockets on Android.  Xojo's Android effort is moving at a snail's pace and sadly I don't imagine that I can start that port anytime soon.  Unfortunately I don't have the time - and perhaps the high-level language expertise - to learn native Android app development.

Last summer a software developer I had been working with on another project, Jim T, kindly offered to write an Android app.  It was his way to relearn Android development and he enjoyed playing with the tCam cameras.  It was much more effort than he originally imagined but to my amazement, he stuck with it in his spare time.  I have helped him test the app and given advice and suggestions and he is finally ready for other people to start testing. 

So if you have a tCam-Mini or are building a tCam, I hope you'll consider playing with this app.

Knowing that the prices for web development are too different I advice using Zenbit Tech's Calculator Service for application development cost is truly helpful for businesses and developers who want to estimate their expenses accurately. Your service is user-friendly, accurate and efficient, making it easier for clients to plan their budget and make informed decisions. Keep up the excellent work!
