What's New in Parallel

1.4.0

October 3, 2026

In this version I mainly worked on how far a timeline can reach. There is hardly a limit any more: it runs from the Big Bang to today, and a single zoom brings all of it onto one screen. Earth & Life A new built-in collection, free for everyone: 79 entries from the Big Bang to the last mammoth. Geological eras, the first life, the dinosaurs and the rise of humans, each with a link to its Wikipedia article. Show it from the Collections tab. Billions of years at a glance The timeline now reaches as far as your entries reach. Zoomed all the way out, every collection fits on one screen, whether it spans two hundred years or four billion. More categories Sport and Nature have been added. You can create as many categories of your own as you like, and once typed they are there for your next entry. Plus many small fixes and improvements.

User reviews

Almost perfect

App works very well and visually nice too, as long as you want to use it with our existing timeline. It would instantly increase its possible audience (think fiction writers) if it would allow custom dates. For example, I’m trying to gather data on a fictional story that not only uses one set of dates (such as BC/AC) but has 4 different (sequential) calendars, each starting with a year 1. Converting all these fictional dates to the existing model is very cumbersome.

[Update] Received a good developers response. Thank you for that idea! Unfortunately they are not parallel timelines but still linear. Looking forward to future versions of this app.

Response from developer

Thank you, that is a really useful suggestion! Custom date systems are not in the app today, and you are right that converting fictional dates by hand is tedious… I have already added your idea to my list for a future update. As a workaround it might help to put each of the four calendars in its own collection. The app shows collections side by side, so at least the eras would stay visually separated. Thanks again for the detailed feedback.
