### 1/5 — Disappointment all around

*2026-07-17*

Full of bugs, constantly hanging, shortcuts broken. This version is not ready for release. Stick to v. 3 for now.

Update: Ver. 4.2 is slightly better than previous iterations, but the app still lags and spins wheels upon the slightest change. Sometimes views come up blank. The Activity indicator seems to have some animation, but it does not seem to reliably indicate the presence or nature of activity. Sidebar folder counts are slow to update, and the sidebar includes two items of limited value that cannot be removed. Settings and Activity buttons are hidden in a sidebar menu where v. 3 had them conveniently in a toolbar; in other views, they can be added, but the mechanism for doing so in Settings is opaque. Deleting the app does not necessarily delete its data, despite what they say; I had such a mess from my previously deleted v. 4 installation that I had to restore a backup on Mac and start over. Setting up sync from scratch was no picnic, either. This version, while usable, is a disappointment; I thought they would be further along by now—but the emphasis seems to be on adding features rather than improving performance. Anyone sitting on the fence may want to wait for 4.3, or longer.

Update: I’m lowering the star rating after a week or so of using 4.2, which is incredibly *slow*, even on an iPad Pro M4. Lots of spinning wheels, no quick checks of anything, frequent capture fails from extension. Wish I had not “upgraded.”

### 5/5 — Layout and menus less functional

*2026-07-10, version 4.2*

I appreciate the vagaries of the current os, but the os is functioning better on iPad now than on initial release. Honestly I don’t think this V4 app is yet. I’ve gone back to V3 on iPad.

Update - Latest version much improved 👍

### 3/5 — Usable but still disappointing

*2026-07-10, version 4.2*

### 5/5 — Excellent Information Manager

*2026-06-11*

This is an awesome tool. It captures information logically, effectively and efficiently. When saving the information, it preserves the format and images better than any of the notebook apps I have tried. It’s not as “sexy” as the notebook apps, but it does a better job at filtering out clutter and capturing what you need. I highly recommend it!

### 1/5 — Loved the app

*2026-05-29*

Quite disappointed that the app became only yearly subscription based. The ios app is useless in this version without yearly license.
The dt togo3 is down so I’ll keep using it until it will stop working hope to find good alternative with one time based license.

### 3/5 — Layout and menus less functional

*2026-05-24, version 4.1.1*

I appreciate the vagaries of the current os, but the os is functioning better on iPad now than on initial release. Honestly I don’t think this V4 app is yet. I’ve gone back to V3 on iPad.

### 5/5 — Best

*2026-05-18*

Devonthink 4 just the best database management system I’ve ever used.

### 5/5 — The best

*2026-04-16*

I don't know what to say about Devonthink. It is such a good app in so many ways. If I were limited to one application it would be Devonthink hands down. The to Go app has continued to get better and better. This release(4.1) looks like some welcome upgrades.

### 3/5 — beta release

*2026-04-06*

i celebrate the entire devonthink catalog but sadly this version of dttg is riddled with bugs that add a lot of friction for reading pdfs and annotating - my prime use case for this app. including text highlighting and not saving page positioning and reading place. don’t swipe the ios notification shade down if you are reading long form content because chances are you’ll lose your place.

### 2/5 — It’s ok

*2026-03-04*

The UI is clunky, the sync speed is so-so, the settings are non-intuitive: but it more or less does what it says it will do.

Update - no, it doesn’t do what it says it will. I was able to sync and download items the first couple days, but for the past week every attempt to download and read an item on my phone has given a spinner for 30 seconds and then an app crash. Yes I’ve verified and repaired, like a caveman (why are users expected to look after database maintenance in 2026?) And things still spin and crash. Sometimes if I’m lucky I’ll see the clickable “download 433 bytes” or whatever but that link does nothing. 

I’ve paid for maybe 3 years worth of DtTG and I think I’ve successfully read maybe three items on my phone in that period.

## Version history (last 5 releases)

### 4.2.2 — 2026-08-24

This maintenance release gives the selected item in the sidebar better contrast and no longer shows actions as icons if there's just one action in the row. It also improves sync robustness and fixes a range of issues and crashes.

### 4.2.1 — 2026-07-30

This maintenance release focuses on stability and performance. Item counting is faster and sync downloads data more quickly by matching the Mac's concurrent connection count. We have also fixed a range of crashes and smaller issues.

### 4.2 — 2026-07-08

This release introduces Zen mode for distraction-free reading and editing, a redesigned icon view, and an updated OCR engine with improved accuracy and language support. Create new images or edit existing pictures with the new AI image creation popover, and add notes or scan documents right from the Control Center.

Quickly navigate your databases with your favorites right on the databases list. Color groups and tags — all synchronized with the Mac — and order documents manually if needed. The chat can highlight text passages and ignores documents from databases you exclude.

NOTE: We're naming this release after the Chandra X-ray Observatory, NASA's flagship X-ray telescope launched in 1999 and itself named after the astrophysicist Subrahmanyan Chandrasekhar (1910–1995). Chandrasekhar determined the mass limit above which a white dwarf star cannot support itself against gravitational collapse, laying the groundwork for our understanding of neutron stars and black holes. His work reminds us that perseverance can reveal truths about the universe even long before anyone has the means to observe them.

### 4.1.3 — 2026-06-11

This maintenance release gives the integrated help pages a visual overhaul and resolves a number of issues, including a crash in the chat, UI delays, and deadlocks. It also fixes unformatted dates in feed articles and syncing bundle documents.

### 4.1.2 — 2026-05-29

This maintenance release adds emergency notification support so we can reach you quickly if a critical fix is held up for some reason. It also fixes a range of issues, including ones related to item counting, wrong RSS article dates, and non-functioning chat exclusion controls.
