Very good app better than alfred in free tier. The upload to google drive is a really cool feature and my galaxy j5 (android 4). Yep it's old but it works and got a second live as camera. The replays in the app work like a charm, and it did only crash once in 1/2 usage which was my fault as the storage of the camera phone was to full and the phone crashed. This calls for an auto delete feature which deletes the oldest pics or vids from the phone automatically if storage gets full.

Hello Dev, great app. My own gripes is that the thumbnails of the video clips or pictures is not the same as the app time stamp. The video clip thumbnails are worse because about 4 thumbnails keeps repeating for all app time stamps and about 80% are black screen thumbnails. Any fix? Thanks.

Super good and free, but therefore being free it has it bad things, you can't view the camera in real time for more than a couple of minutes before it closes and gives you and ad, recordings are almost impossible to view or download, super hard to set motion schedule time, but if you just need to check in on Eine a while to see what's going on, is a good app for that o and yeah it has Zoom something other app don't offered

Works better than any of the 10 different security cameras I have tried over the years.

Been using this app for a while with a cell phone as my security camera. Overall I have liked it especially since it's free. But it will randomly stop working. Today I have added another camera to the account, and now it's been kicking the monitor phone and the camera phone offline causing me to have to log back in manually on each phone. Meanwhile, I think I have security cameras, and I actually don't because they've stopped working. If this continues I'll have to find another app.

App continually opens by itself when not in use; it is a huge distraction and bothersome. Unfortunately, I finally had to uninstall the app - I couldn't get anything done or watch anything with the persistent interruption.

I uninstalled this app and happy to use Alfred Camera. No battery consumption no connection issue... great alfred camera

After several attempts to receive a response from support I will try here. I have two of three cameras that will not show the photos recorded but always states it is full. Shows loading for 10 minutes or longer. How can I delete the photos?

Last update totally killed it for me. I would have paid for the app but subscription model for the cloud functions I didn't want to use was a no-go. I was kind of ok with the frustrating amount of ads. But with the last update it simply crashes when try to live view or record with my old samsung s3. And developer decided the old version app will not stream. I'll just install an ipcam app and set up an old laptop as server or get cheap cameras instead of dealing with this app
