What's New in Parallel

1.2.0

August 25, 2026

In this version I mainly worked on importing your own collections. Importing is simpler There are now three ways into a collection of your own: add the entries yourself in the app, bring them in from a file, or paste a copied table straight in as text. So no file is needed at all. A free sample collection: Ancient Rome Ancient Rome comes with the app as a sample collection, no Pro needed. It shows you how an import works, and the collection stays with you afterwards. Tap a collection, the timeline follows Tap a collection in the list and the timeline jumps straight to its period. Save the focus view to Photos The focus view can now be saved directly to Photos, in different image formats if you like. New premium pack: Cities of the World 181 cities across six continents, from 9000 BC to today. Plus many small improvements. You can swipe an entry sideways in the list to edit, copy or delete it, and scrolling and zooming the timeline should feel smoother.

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.
