Koofr vs Readwise
A side-by-side editorial comparison of Koofr and Readwise — release velocity, themes, recent moves, and the top alternatives to consider.
Koofr vs Readwise: at a glance
What is Koofr?
Koofr rebuilt its iOS app around automatic backup, becoming a destination rather than a folder.
Koofr is a European consumer cloud storage service, with Koofr Vault as its client-side encrypted layer. The dominant event of the past year is a complete rewrite of the iOS app, shipped as 4.0.0 in June: native Files app integration, automatic background photo and video backup, saving from other apps' share sheets, HEIC or JPEG choice on upload, labels, and search by file type and label. Document scanning followed in July. The rest of the feed is a mix of Vault polish, promotional discounts, and incident notices — a DDoS in April, a Google domain flagging in January.
What is Readwise?
Two big swings in July and August, and since then Readwise has been paying the bill.
Readwise shipped a full mobile rewrite in late July and library-wide Ghostreader a fortnight later, and the weekly changelogs since have been almost entirely repair. The August 28 week is typical: thirteen fixes against five real improvements, spread across EPUB handling, chart and video embeds, Ghostreader chat on both mobile platforms, and Boox e-ink devices. The one consistent addition each week is parsing coverage for more publishers.

Koofr rebuilt its iOS app around automatic backup, becoming a destination rather than a folder.
◆ Current state
Koofr is a European consumer cloud storage service, with Koofr Vault as its client-side encrypted layer. The dominant event of the past year is a complete rewrite of the iOS app, shipped as 4.0.0 in June: native Files app integration, automatic background photo and video backup, saving from other apps' share sheets, HEIC or JPEG choice on upload, labels, and search by file type and label. Document scanning followed in July. The rest of the feed is a mix of Vault polish, promotional discounts, and incident notices — a DDoS in April, a Google domain flagging in January.
◆ Where it's heading
The company's attention is clearly on mobile parity with the large providers, and the sequencing shows it: rebuild the app, then add automatic backup, then add the capture features that make the phone a source rather than a viewer. Koofr Vault gets steady but smaller attention, keeping the encrypted layer close behind the main product. The recurring discount campaigns and gift card work suggest consumer acquisition matters as much as feature depth here.
◆ Prediction
Automatic background backup shipped on iOS with an explicit note about how iOS schedules uploads; the same capability reaching Android at comparable quality is the obvious next step, since the feed already treats the two platforms as a pair for Vault changes.
Readwise
6.3COLLAB
Two big swings in July and August, and since then Readwise has been paying the bill.
◆ Current state
Readwise shipped a full mobile rewrite in late July and library-wide Ghostreader a fortnight later, and the weekly changelogs since have been almost entirely repair. The August 28 week is typical: thirteen fixes against five real improvements, spread across EPUB handling, chart and video embeds, Ghostreader chat on both mobile platforms, and Boox e-ink devices. The one consistent addition each week is parsing coverage for more publishers.
◆ Where it's heading
The fix list is a map of where the rewrite is still settling — pagination and layout stability on Android tablets, chat sheets and message sending on mobile, exports arriving with page CSS attached. Underneath that, small capabilities keep arriving quietly: Apple Books folder-EPUBs now upload, interactive charts render as linked images instead of an import notice, non-Latin titles survive the trip to Kindle. The company is broadening what it can ingest and export while stabilising what it rebuilt.
◆ Prediction
Expect the weekly cadence to hold with fixes still outnumbering additions, and the remaining Boox and Android tablet issues to keep appearing until the mobile rewrite fully settles.
