JOI App: No Store, No Install, No Trace on Your Bill
There is no JOI app in the App Store, and there is not going to be. This one runs as a web app instead: you open it in your browser, and if you want it on your home screen you can put it there without downloading anything. Free, 18+.
Play Edge Trainer →Why there is no app to download
Apple and Google do not list adult apps, so anything calling itself a JOI app on a store is either not what it says it is or is about to be pulled. A web app sidesteps the whole problem. Nothing gets installed, nothing shows up in a purchase history, and there is no listing to disappear one Tuesday.
Putting it on your home screen
If you want a one-tap icon, your browser will do it. On iPhone it is Share, then Add to Home Screen. On Android it is the browser menu, then Install or Add to home screen. Two things worth knowing before you do:
- The icon is labelled Interval. Not the site name, not anything obvious. Someone glancing at your phone sees a timer app.
- It opens full screen, without the browser bar, so it behaves like a normal app once it is there.
Or skip all that and just use a bookmark. It works exactly the same.
What it does once it is open
Timed rounds of Build, Edge, Surf, Cooldown and, on the last round only, Finish. Four lengths: Easy 2 rounds and about 5:53, Medium 3 and 7:42, Hard 4 and 10:39, Master 5 and 13:33. 59 trainers with their own names and personalities, audio as a metronome or real recorded moans, on-screen edge-control tips you can switch off, and stats when you are done.
Accounts, and the lack of them
No signup. No email, no password, no profile. That means nothing to leak and nothing to delete later, and it also means your stats live on that device rather than in an account somewhere. Fair trade.
If you would rather just try it in a tab first, the JOI game page explains the session, and free JOI covers what you get without paying, which is all of it.
FAQ
Is there a JOI app I can download?
Not from the app stores, because they do not list adult apps. This one is a web app: it runs in your browser and you can add it to your home screen without installing anything.
How do I add it to my home screen?
On iPhone, tap Share then Add to Home Screen. On Android, open the browser menu and choose Install or Add to home screen. It then opens full screen like a normal app.
What name shows under the icon?
Interval. The home-screen icon is deliberately unremarkable, so a glance at your phone shows what looks like a timer app.
Does it work offline?
Partly. Some of it is cached once you have loaded it, but treat it as an online thing and keep a connection.
Does it cost anything or need an account?
No to both. No signup, no email, no card. Your session stats stay on the device rather than in an account.
