I'm working on a new calibre library app - Calibre LibraLink

setherd · 03-21-2026, 03:46 PM

Please tell me if this isn't allowed. But with the abandonment of other apps. And with how good AI is getting, I'm trying to write my own app so I can Look at my libraries and read books wherever. I've got the first versions working on Android, iPhone, and iPad and have it sync into Google Drive and Dropbox. I also added Project Gutenberg.
Is anyone interested in looking at it, maybe giving feedback?

Screenshots here: https://sahollen.com/apps/

Testing 25 (1.3.9)

for Android & Apple test flight available. PM me for either!!

Latest changes: international language support, you can pick the language and format in Project Guternberg, seperate local calibre content server connection. can delete individual connections. Fixed web DAV.
Your cloud library now loads 100 books at a time instead of all at once — much faster on large collections
Improved performance for large libraries — books now load instantly and more appear as you scroll
Fixed a bug where the library folder browser and sync could fail on some WebDAV servers
MS One Drive still not working.
Series titles should wrap around to display nicer.
I sped up how it connects to the content server. It grabs 500 titles at a time. for large libraries it may take a few minutes. But I'm worried grabbing more at a time will use up too much ram on older or less powerful devices.
If anyone has an ereader I'd love to hear how the performace is.

Android testers, you should see an option To purchase library access. Just click on it and it will go through with a test card.
Apple users, I'm uploading a new version that will just have everything unlocked.

If someone could test the web DAV access and let me know if there's problems, I would be grateful.

I'd be happy to look at the iOS version.

Are you aware of JustRead.app and Bookshelves? They are both new iOS ePub Readers, with various features. But a new entry is worth a look.

setherd · 03-21-2026, 07:28 PM

This isn't a reader, it just downloads the files to your device and then you can open it with whatever you want. But thank you! Hopefully in the next couple days I can get it ready for people to test.

dunhill · 03-21-2026, 08:46 PM

Add me to the tester list, I'm interested in the offer. I use Android.

pdurrant · 03-22-2026, 03:40 AM

A replacement for calibre link, which seems to have been abandoned? Yes, I'l like to try that.

Some screen shots there. I have to get setup with the app stores to be able to give download links. I think I can email APK fiels to andorid users if you don't want to wait.

I store my calibre library locally. I'd like an option to connect up to the calibre server, and an option to download all books easily (that might already be there, of course).

For doing beta releases on iOS, another developer has used an app called TestFlight. I don't know if that's a standard Apple thing or a third party app.

Testflight is an Apple app. It's used for beta testing.

setherd · 03-24-2026, 05:12 PM

setherd · 03-28-2026, 02:46 PM

Setting up the Google Play Store. What a pain in the butt. But hopefully in the next few days I can send it to some for testing.

setherd · 03-28-2026, 04:12 PM

OK it might be working on android. Please send me a DM and your country. I'll send you a link. If that doens't work I may need an email address.

While I see the option to add cloud libraries they appear to be locked out and require the purchase of the cloud sync option.
