How to bring your TV Time ZIP
In the app, open Settings, My data, Import from another app, and pick the file as it came from TV Time, without unzipping it. The ZIP holds dozens of spreadsheets, and only the four that tell your story are opened: watched episodes, the state of each show, movies and movie ratings. The ones holding passwords, access tokens and IP addresses are never even decompressed.
If you requested your data by email, you got a password-protected ZIP, with the password in a second email. In that case, open the ZIP with it on a computer and send just the tracking-prod-records-v2.csv file, or zip the folder again without a password. If you used the TV Time Out extension, you can send the CSVs it generated.
Each show is matched by the TheTVDB id inside the file, not by its name, so shows with similar names don't get mixed up. Before anything is saved, a preview shows what goes to the queue, what goes to the collection and what had no match in the catalog, and you decide what comes in.
What comes over, and what stays behind
A show you were watching comes in as in progress, marked at the furthest episode you watched: rewatching the pilot after season four doesn't send you back to season one. A show you archived on TV Time goes to the collection, marked where you stopped. Followed shows you hadn't started, and anything saved for later, go into the queue.
A watched movie arrives with the date you marked it, and with your rating when you gave one. Movies on your watchlist go into the queue. If the same movie was on both lists, the fact that you watched it wins.
What stays behind is what has no place here or can't be brought over safely: the log of every single episode (what remains is how far you got), show and episode ratings, reactions and custom lists. We'd rather leave something out than bring it in wrong, because a wrong item in your archive is worse than a missing one.
Tracking shows here: what changes
The everyday gesture stays: finish an episode, tap "Watched it" and the show moves to the next one. You can pick a season and episode by hand to fix things, and the show leaves the in-progress section once you finish it and rate it.
What's different, and better said up front: NextWish doesn't have TV Time's weekly episode calendar, and it doesn't alert you on every new episode. The alert it does have is for releases: a show, movie or game that isn't out yet goes into the queue with its date, and the app tells you on the day.
In exchange, your shows share a profile with movies, books, games and music, your friends see what you're watching, and a group decides together what to watch on the weekend, with each person answering from their own notification.
