Project Goals
This project is written to be able to benefit from furaffinity.net content on iOS, and now in preview on Android, through a more friendly and native experience. It also serves as a learning project for the technologies mentioned later. It can also be useful to other people and is thus provided by the means of this opensource GitHub project.
Features
Installation
iOS: see the steps on the official website: furaffinity.app.
Android (preview): download the FurAffinity-<version>-<commit>.apk file attached to the latest release and open it on your phone; Android will ask you to allow installing apps from your browser or file manager. The Android version is a subset of the iOS app for now: the Followed feed, submissions (images, stories and music, with favorites, saving, sharing and comments) and Settings. On first launch Fur Affinity's Cloudflare check asks you to tap "Verify you are human" once.
Can I trust this app?
The application is unofficial so you may wonder if it's trying to steal your Fur Affinity account or some other personal information. The fact that you have access to the full source code lets you check how it works and specifically the fact that no password is ever known to the application. The app also does not try to use any personal information beyond what is stricly necessary to let the application run: it reads the submissions listed on your account only to give you access to them in the app, etc.
How does it get access to my account?
The app displays furaffinity.net login webpage to let you enter account details. These are communicated by the web browser to furaffinity.net which will then create cookies that allow your session to remain active. The account details communication only happen between the web browser and furaffinity.net server, the app only has access to the created cookies. The application then reuses these cookies to make requests to furaffinity.net as if connected with your account.
Will I get banned from Fur Affinity for using this app?
As of May 2022, Fur Affinity staff allows the use of the application as long as it does not make excessive requests to furaffinity.net. This goes against apps that download the full gallery of a user for instance, but not against this app which, from furaffinity.net's point of view, behaves very similarly to a usual web browsing experience.
