The problem with having three apps
People who log what they consume usually end up with one app per universe: one for films, one for books, one for games. Each works fine on its own, and the cost shows up in the sum: three accounts, three friend lists, three screens to open when you want to remember what you did this year.
The bigger cost is not time, it is that the answer ends up split. "What did I love in 2026" exists in three places and in none: the record that defined the year is in one app, the series you binged with the same person is in another, and the comparison that would make sense never happens.
And there is a social effect: your friends are not on all three. You follow a different set of people in each, and the conversation worth having, the one that crosses universes, has nowhere to happen.
What a single app gains, and what it gives up
What you gain is the whole reading: one profile, one friend list, one feed, one year-end recap with everything in it. Achievements and the ranking add up all six universes, and friend recommendations cross over: someone can send you a book because of the film you just rated.
What you give up is worth stating plainly: specific depth. An app dedicated to cinema has director lists, full cast and per-decade statistics; one dedicated to books has monthly page counts and a yearly challenge. NextWish does not have those layers, and does not intend to have all of them.
So the choice is about what you do with the log. If you want the deepest data on a single universe, the specialist app wins. If what you want is to remember, share and decide with other people, the split log is what gets in the way, and putting it together is worth more than the extra statistic.
Moving over without retyping everything
The biggest cost of switching apps is the history. That is why importing exists: you can bring your Steam library by connecting the account, and you can upload an export file from other movie and TV services.
The import runs on the server, in the background, and tells you when it is done: you can close the app halfway. Progress is saved in batches, so a dropped connection resumes where it stopped.
You choose what comes in, and nothing is published without you asking. Anything with no match in the catalog is left out rather than added under the wrong title, which is the flaw that makes someone abandon a migration on day one.
