It seems like you want me to help with downloading a visual novel called 'Class of '09' for iPhone and providing instructions on how to use it. I'd be happy to assist you!

Firstly, let's download the visual novel. Since it's not available in the USA due to geo-restrictions, we'll need to use a VPN (Virtual Private Network) to access it. Here are the steps:

1. Get a reliable VPN service that allows streaming on Hulu.

2. Install and configure the VPN app on your iPhone or iPad.

3. Open the Hulu app and sign in with your account credentials.

4. Search for 'Class of '09' in the Hulu catalog.

5. Click on the show, and you should be able to watch it now that you're connected through the VPN.

Next, let's talk about using the visual novel. It seems like you'll need to add subtitles for a specific episode (End of the Moon Episode 39). Here are the steps:

1. Download the Srt format file for the episode and move it to the 'Movie/Tv Series Folder'.

2. Open MX player on your iPhone or iPad.

3. Click on the right-side button, then select 'Subtitle' option, and finally click on 'Open' option.

4. Navigate to the subtitle file and click on it.

As for using the visual novel itself, here's a brief overview:

* Experience the ultimate anti-visual novel, Class of '09, where you play as an anime girl causing chaos in the lives of your potential suitors.

* With late 2000s aesthetic and hilarious social accuracy, navigate your way through 15 different endings and unlock bonus lore and scenes.

* This unique visual novel auto-progresses, so you don't have to worry about tedious note-taking or reading.

If you're interested in trying out the note-taking app mentioned earlier (Notability), it's available for free download. It's a powerful yet simple tool that allows you to capture and prioritize ideas, projects, and to-do lists. You can use it in conjunction with Class of '09 or separately as needed.

Let me know if you have any further questions or need help with anything else!
