Can you give me some help while installing "F3J Timmer"? I've tried it but it was not successful. If I'm online the software works, but in offline mode it doesn't work. Cna you provide some info?
I have found out that F3J Timer is actually an Android based application which means that it requires an Android to properly install it. Since I possess one, I've installed the app and then turned off my Internet Connectivity. There was no error or information regarding of what I've done. The software worked normally while being in the offline mode.
If you have an older version of the software, then I recommend checking the Google Play Store to download the latest version fo the product.
Here is the link to the application page at Google Play Store: https://play.google.com/store/apps/details?id=net.f3j.android.timer.f3j&hl=en
