Editor's Review
With 10K+ installs, 9toon sits at the small end of the entertainment category, and its developer, toroyan, publishes very little about it. The name and the category both point at serialised comics: a reader that lists titles, opens them in a scrolling view and remembers which episode you reached.
Apps this size usually work well enough for the specific reading habit they were built around, and a 4.63 average suggests the people using it are getting what they came for. What that score cannot tell you is how large the library is, which languages it covers, or how the catalogue is sourced. Those are the questions to answer on the first launch, before any real reading time goes into it.
Treat it as a niche reader rather than a major storefront, and judge it on one thing only: whether the titles you want actually appear inside it.
Features
Title list built for serialised, episode-based comics
Scrolling reader view suited to vertical strips
Keeps track of the last episode opened in each series
Small download footprint typical of single-purpose readers
Pros
A 4.63 average from its regular users is a good sign for an app this obscure
Simple enough to understand within a minute of opening it
Cons
The developer offers almost no public information about the app or its catalogue
A 10K+ install base means few reviews and little community help if something breaks
No way to judge library size or licensing before installing and looking
