Short answer first: there is no official AO3 app. Archive of Our Own has never released an app for Android or iPhone, and the Organization for Transformative Works (OTW) says so plainly in its own FAQ — mobile apps are not currently available. If you see an app in a store calling itself the official AO3 app, it is not from the OTW. It is a third-party reader, and some of them are built to steal logins.
The good news is you do not need one. AO3 was built to work in a phone browser. The site adjusts to your screen, your login stays in the browser, and you can pin it to your home screen so it opens full screen, just like an app. That takes about a minute to set up, and this page walks you through it. If you want the steps on their own page, read our walkthrough on how to add AO3 to your home screen for Android and iPhone.
Quick facts
- Official app: none. No Android app, no iPhone app, nothing in the works that the OTW has announced.
- Official site: archiveofourown.org — the only place to log in, post, comment and manage your account.
- Run by: the Organization for Transformative Works (OTW), a nonprofit. AO3 is fan-run and ad-free.
- Best phone setup: open the site in Chrome or Safari and use Add to Home Screen.
- Offline reading: every work can be downloaded as EPUB, AZW3, MOBI, PDF or HTML and read in an e-reader app.
- Cost: free. Any "AO3 app" asking for a subscription to read is a red flag.
Why is there no AO3 app?
AO3 runs on volunteer time and donation money. Building and maintaining two native apps, one for Android and one for iOS, would take developers the project does not have, and app stores add their own problems. Store rules on mature content are strict, and a big share of AO3 would clash with them. An app also has to be reviewed and approved by Apple or Google every time it changes.
So the OTW put the work into the website instead. The pages are responsive, which means the same site reshapes itself for a phone, a tablet or a laptop. Search, filters, bookmarks, subscriptions, comments and posting all work in the browser. You lose nothing by skipping the app stores. You actually gain safety, because there is exactly one real front door and it is the website.
Searches for an AO3 app spiked again in November 2026 for a simple reason. AO3 went down on 29 October 2026 after a security incident and stayed in extended maintenance for over two weeks. It came back on 15 November 2026 with limited functionality while the team finished repairs. A lot of readers went looking for an app during the outage, hoping an app would still work. It would not have. An app reads from the same servers, so when the site is down, every reader app is down too.
The safe way to read AO3 on your phone
Use your browser, and pin the site to your home screen. You get an icon next to your other apps, the site opens full screen without the browser bars, and you stay logged in. Here is the short version.
Android (Chrome)
- Open Chrome and go to archiveofourown.org. Log in if you want your bookmarks and subscriptions handy.
- Tap the three-dot menu in the top right corner.
- Tap "Add to Home screen" (on newer versions it may say "Install app" — both do the same thing here).
- Name it AO3 and tap Add. The icon now sits on your home screen.
iPhone (Safari)
- Open Safari and go to archiveofourown.org. It has to be Safari — other iPhone browsers cannot add sites to the home screen.
- Tap the Share button at the bottom of the screen.
- Scroll down and tap "Add to Home Screen".
- Name it AO3 and tap Add in the top right.
That is the closest thing to an official AO3 app that exists, and it is the setup the OTW itself points readers to. Our download page explains why there is no file to install and how to spot the fake installers going around.
Unofficial reader apps and their risks
Search any app store for "AO3" and you will find reader apps with names close to Archive of Our Own. A few are honest fan projects that just wrap the website in a shell. Plenty are not. The risks are real either way:
- Login theft. If an app asks for your AO3 username and password, it can store them, reuse them, or sell them. There is no safe way for a third-party app to ask for your password.
- Broken features. Posting, commenting, kudos and account settings often fail in wrappers. For anything beyond reading, the website is the only reliable route.
- Ads and trackers. AO3 itself has no ads. Reader apps often add their own ads and tracking on top of a free, ad-free site.
- Sudden shutdowns. Stores remove these apps without warning, and your saved reading lists inside them go with them.
Our full breakdown, is there an official AO3 app, goes through the warning signs one by one. The one rule that keeps you safe: never type your AO3 password anywhere except archiveofourown.org.
Reading offline without an app
Long flight, bad signal, data cap — AO3 handles that too. Open any work, tap the Download button at the top, and pick a format. EPUB works almost everywhere. AZW3 is for Kindle. MOBI suits older e-readers. PDF keeps the layout fixed, and HTML saves the whole work as one page.
Then read the file in an e-reader app you already trust: Apple Books on iPhone, Google Play Books on Android, the Kindle app for AZW3 files, or Moon+ Reader if you like lots of settings. These apps hold your place, let you change text size, and work fully offline. We cover the steps and format choices in detail in our post on how to read AO3 offline.
Frequently asked questions
Is there an official AO3 app for Android?
No. There is no official app for Android, iPhone or any other platform. Anything in the Play Store using the AO3 name is third-party.
Why does the Play Store show AO3 apps then?
Anyone can publish a reader app and name it something similar. A store listing does not mean the OTW made it or approved it. Check the developer name — if it is not the Organization for Transformative Works, it is not official.
Can I post and comment from my phone?
Yes, in your browser. Posting works, comments work, bookmarks and subscriptions work. The mobile site is the full site, just rearranged for a smaller screen.
An app asked me to pay to keep reading. Is that real?
No. Reading on AO3 is free and always has been. Close the app, change your password on the real site if you entered it, and read in your browser instead.
AO3 was down for weeks. Would an app have helped?
No. The outage in late October and November 2026 was on AO3's servers after a security incident. Every app pulls from those same servers, so all of them were down too. The site returned on 15 November 2026 with limited functionality while repairs finished.
The bottom line
Skip the app stores for this one. Bookmark archiveofourown.org, pin it to your home screen, and download works as EPUB when you want to read offline. You get the whole archive, your account stays safe, and nobody slips ads or trackers between you and the story. If a friend sends you a link to an "official AO3 app," send them this page instead.
