Question about if there is a Data Usage app with these features?

Hello everybody. Im new to this site and i know that there are people here who are very talented and i would like to thank them for their help that they provide. This site have helped me a great deal even though i just browse it.

Short version:

So, my service provider have this data plan for me which consists of 2 parts:

1- 2 GB during the month (except the duration of the second part).
2- 1 GB everyday and it is provided from 12:00 am to 6:00 am

So, if the time is anything but the second duration, my service provider will monitor my 2 GB consumption. And i believe the description for the second part of the plan is clear.

I would love it if there was an app that can monitors this data plan and can put caps on it and update accordingly on a daily basis. Is there such an app?

Thanks in advance.

TL:DR version:

Now, i like to download big files sometimes and to automate the process i used an app called automate it and it helped me in setting logical operators for the time interval of the second part and controls switching on/off my data connection and wifi but my current setup relies on me updating the data usage app of the system on a daily basis which is cumbersome. What happens is ill give my device the 1 gb allowance\cap on a daily basis. It will reach it during the 12-6 am interval. The system will turn the data connection off. Automate it will realize that and turn on the wifi connection to continue downloading. All of this while im a sleep which is awesome but i have to update the 1 gb allowance on a daily basis which is combursome and i would love it if there was an app that can put 2 data caps on my internet usage as based on the description of my data plan.

Thanks in advance.
