Is this a website you own? Did you program it yourself, or are you using 3rd party software?

Also, what OS are you trying to program this app for? Android, Windows, Blackberry, Amazon, iOS?

I could run through some basic concepts but I will link a video for now as it covers some good stuff, at an incredibly basic level you could probably make something with wget or something similar, do a file compare (possibly having dumped some strings first) and then get it to fire off an alert of whatever form you can think to do from that, and have it all run as a cron job or scheduled task. After that though it gets more complex and you will probably have to learn some web tools like curl https://curl.haxx.se/ , and you might be able to get something done with http://www.squid-cache.org/ if you get fancy but I don't really know that.



Do bear in mind though that if it is a website you own there are far better ways to set about this, if it is not a website you own then they may not want you to be doing this and may actively be trying to stop it.
For a very basic website it might even still be able to use modified dates and wget but a lot of php sites (probably most sites out there) will generate on the spot and have dates reflecting that.

I just use the Check4Change plugin... But I have to remember to keep all the tabs open all the time.

What language? Do you want to do it a certain way? Can you view the numbers without logging into the website? So many questions to ask tbh xd Ik how to, but it depends on how you want to go about it.
