x86_64

Download palimpsest-0.1.8-android-x86_64.apk (69 MB)

Install

1. Download the .apk on your phone.
2. Open it. Android will ask once to allow installs from the app you downloaded with (usually Chrome or your file manager).
3. Launch Ink and Echo and import an audiobook + ebook.

Coming from v0.1.0: uninstall the existing Ink and Echo first. v0.1.1+ is signed with a different key and Android won't upgrade in-place. From v0.1.1 forward, updates install over the top.

Updates: there's no auto-update without Play Store. Obtainium can watch this page's GitHub releases and prompt for updates the way Play Store does — paste the repo URL https://github.com/rRexhepi/ink-and-echo-app into Obtainium to subscribe.

Google Play listing is on the roadmap.

Windows

Windows 10 1903 or later. x64 and ARM64.

Download ink_and_echo-0.1.8-windows-x64.exe (21 MB)

Microsoft Store listing on the roadmap.

Linux

Ubuntu 22.04+, Debian 12+, Pop!_OS, Mint. x86_64.

Two builds. Both ship the same binary; the difference is whether Calibre is pulled in as a dependency.

Lite — recommended for most

EPUB + MOBI import, audiobook + sync. ~80 MB installed. No Calibre.

Download ink-and-echo_0.1.8_amd64.deb (23 MB)

Double-click the file in Files to install via the Software Center, or in a terminal:

sudo apt install ~/Downloads/ink-and-echo_0.1.8_amd64.deb

Full — every format

Adds Calibre as a hard dependency so PDF, AZW3, RTF, DOCX, LIT, FB2 and the rest import out of the box. ~620 MB installed (Calibre brings Python + Qt + WebEngine).

Download ink-and-echo-full_0.1.8_amd64.deb (23 MB)

Double-click the file in Files to install via the Software Center, or in a terminal:

sudo apt install ~/Downloads/ink-and-echo-full_0.1.8_amd64.deb

Launch from your app menu (search "Ink and Echo") or run ink_and_echo from a terminal. The lite build can pick up Calibre later with sudo apt install calibre.

Other distros: a Flatpak / AppImage build is on the roadmap. For now, build from source.
