Thank you for reaching out on the community and telling us about
your situation. You should be able to use the mobile app for an extended period of time. You are able to retrieve new transactions while using it as well as adjusting any categories as well. I would take some time experimenting with the mobile app to see how to use these functions.Another option that you also have is Quicken on the web which can be access from Quicken.com. This will give you the option to sign in if you have a computer available and want to check on it. You'll want to make sure you sign out and also choose not to remember the account.
If you have any questions on how to use the app please let us know and we'll be happy to answer!Thanks,Quicken Francisco
