Android app ​

The BackIssue Android app is a native companion to your server — not a web page in a wrapper. It reads your library, downloads issues to your phone for offline reading, and lets you add or request comics on the go. Built for phones and tablets alike.

Installing ​

The app is distributed as an APK you install directly (it isn't on the Play Store):

1. On your phone, open the download link.
2. When prompted, allow your browser to install unknown apps (Android asks the first time; you only need to do this once).
3. Open the downloaded file to install, then launch BackIssue.

Keeping the app updated ​

The app updates itself — no need to come back here. When a new version is published you'll get an Update available prompt, and you can check any time from Settings → Check for updates. Tap Download & install, confirm the system prompt, and your servers, sign-ins, and settings are all kept. The first update asks you to allow BackIssue to install apps — a one-time Android permission.

You can still grab the latest APK by hand from the download link if you'd rather.

Signing in ​

On first launch, point the app at your server and sign in:

• Server address — the URL you use in the browser (e.g. https://comics.example.com).
• Username and password — the same account you use on the web. No API keys to copy around.

You can add more than one server and switch between them at any time from Settings → Servers — handy if you run one at home and connect to another. Each server keeps its own sign-in and downloads.

For extra privacy, turn on Require unlock in Settings to ask for your fingerprint or PIN every time the app opens.

Reading ​

The app carries the full reader experience:

• Paged, double-page, and webtoon (continuous scroll) modes, plus right-to-left for manga.
• Pinch to zoom, fit controls, and white-border trimming for scans.
• Resume — it remembers your page and picks up where you left off, and your progress syncs with the web reader and every other device.
• Bookmarks — mark pages and jump between them.
• Layout choices are remembered per series, so manga stays right-to-left webtoon while your other books stay single-page.
• A data saver mode downscales pages when you're on mobile data.

Your reading stats — pages read, issues finished, streak, and most-read series — travel with your account.

Your library, offline ​

• Browse and search everything you own, filter by followed / missing / problem series, and open any series to see which issues you have.
• Home shelves (Continue reading, Next up, New in your library, and the rest) mirror the ones you've enabled on the web.
• Download issues to your device for reading with no signal — on a flight, the train, or anywhere offline. Manage what's stored, and free up space, from Settings → Offline downloads.

Adding & requesting ​

Found something you want while you're out?

• If your account can manage the library, add a series straight from the app.
• If your server runs the Requests plugin and your account can make requests, the add button raises a request for approval instead — the same flow as the web app, including western-only limits if your server enforces them.

What you can do in the app follows your account's permissions exactly, just like on the web.

Activity ​

The Activity view shows the live download queue and recent history from your server, so you can keep an eye on what's fetching without opening a browser.

Requirements ​

• Android 8.0 (Oreo) or newer.
• A reachable BackIssue server, and an account on it. Reading needs the Reader plugin enabled on the server (it is by default).
• HTTPS is recommended so your credentials and library travel securely.
