What's New in Aeon Timeline 3

3.5.123

September 16, 2026

3.5.123: Spreadsheet and Filter Improvements ## Spreadsheet View The following fields can now be shown and edited as columns in the Spreadsheet view: - Date Locked - Avatar - Short Label - Mindmaps - Constraints - Links - Image ## Inspector - Images can now be replaced directly without removing the existing image first. - You can now add a Mindmap field to the Inspector to see which mindmaps an item belongs to or add it to a mindmap. ## Sorting New sorting options have been added to the Spreadsheet view, the Relationship view rows, and the List view: - Avatar - Short Label - Blocks and Blocked By - Relationships - Tags - Image - Links - Attachments The following additional sorting options are available in the Spreadsheet view: - Latest Start and Earliest End - Ongoing - Mindmap - Date Locked - Date Constraints - Narrative Section Label ## Filters New filtering options have been added: - Date parts: Filter by weekday, month, or other parts of a date. - Date locked: Filter by whether dates are locked. - Images, attachments, dependencies, and constraints: Filter by whether an item has them. - Mindmaps: Filter by whether an item is included in a mindmap. - When filtering by a list or text property, relationship, or summary, you can now filter for items with no value. ## Other Fixes - The Collapse All Groups and Expand All Groups menu options are now disabled when the current view is not grouped. - Fixed Select in Inspector not working from the Edit menu. - Added tooltips explaining the cause when the Ongoing option is disabled for the selected item. - Fixed an issue where a locked parent could incorrectly become ongoing when its children changed from ongoing to having a fixed end date. - Fixed custom-calendar and other non-Gregorian dates not exporting correctly to JSON. - Fixed an issue where property dropdowns could still be set for item types that don’t include that property in the Spreadsheet view. - Fixed a minor visual jump when focusing dropdown cells in the Spreadsheet view. - Fixed an issue where the JSON export did not correctly export dates using custom eras other than BC/AD

Far too expensive

Downloading this app only to find it’s 100 bucks if I want to use it beyond the trial period? Very frustrating.

Amazing, Flexible and One of the Best Support Teams to Help. Thank you.

I am a writing a novel series and I decided I would give Aeon Timeline 3 a go. I have used Aeon Two before for other projects, but for a novel.

This app is not for actually writing a novel rather it is for creating the entire framework. Previously I used a number of applications to craft worldviews, characters (profiles, plots, arcs and their all the associated content, relational diagrams), locations and their descriptions, well I could go on. Now I use Aeon Timeline 3 to do all those things and more. Before, I had files every where, now I have just 2 files to look after. My worldview file and my Novel file in Aeon Timeline 3. Life is so much easier, and more time to write instead of looking for stuff all over.

I use Scrivener to write my events / scenes and that won’t change in the foreseeable future. The other fantastic feature is the synchronisation with Scrivener. I can work in either application and synchronise my novel. Best part for me was being able to take all my information in Aeon Time 3 and have it synchronise to Scrivener, so that information was at hand when writing scenes. I love it. Another positive was support documentation and then the customer service which is exceptional. I use it all the time to ask how to do things and to share experience. They won’t to know. Thank you Aeon Timeline 3 for making life easier and thank you to the staff for being so helpful.

this does exactly what i want in a timeline

my make or breaks:
works on mobile- this runs perfect on my ipad and has no problems with the aspect ratio
horizontal timeline- it’s stupid but i can’t explain how many other timelines are vertical and my brain just does not work that way
tags and color markers- i have like 4 stories in the same universe that i want to be able to plan out together due to having some crossover but be able to visually separate them because they are still different stories
the ability to zoom in and out on the timeline- sometimes i want to see every thing and sometimes i like focusing on a specific period of time depending on what i’m doing

some other qol features i like are, the ability to select a character and see what events they’re in, spreadsheet view, character groups, and story arcs.

Good but…

First of all…I LOVE the Mac app, its amazing. The phone app pairs well with it and I love that it syncs between them.

However, the phone app is glitchy a lot of the time. Most common issue is that every time I try to scroll to the bottom of a page or list I can’t tap the bottom option. Its very annoying. Also, if you tilt your phone to the side it will send you back to another menu and you will lose whatever you were working on.

crippled app

The description for this app is deceptive. There is NO option to export data in any way from the iOS app. So on the go, you won’t be able to share anything. The file icon inexplicably drops you into the Files app with no way to get back to the app. The logic of this is baffling.
