I lost my iPhone and all my notes I had on the Notes app. Is there any way I can get into the app using the computer instead?

You should be able to go to icloud.com. Once you are there sign in, once you sign in your notes should be there as long as you have made a backup recently.

If you have made a backup to iCloud or your PC, and you get another iPhone, just restore the new phone from that backup and everything will be there.

If you have synced them to iCloud then you can log into www.icloud.com and go to the notes section

Through iCloud.com, assuming you had the Notes synced with that.
