Preceden alternative: Boromlia vs Preceden

Choose Boromlia if

• Your events need more than a bar: a place on a map, a source, people, tags and photos.
• You want to read one record several ways: a river, cards, a map, spans and, on Advanced, a sortable table.
• A subscription is not what you want: $2.99 once buys one more timeline of up to 50 events, and $49.99 once buys everything Advanced has.
• Your timeline turns on hours as well as years: each timeline sets its own scale, from seconds to years.

Stay with Preceden if

• You mostly need a layered chart for slides: Preceden exports to PowerPoint.
• You keep many small timelines: its free plan allows unlimited timelines of up to 10 events each.

The main difference: a chart versus a record

Preceden starts from the picture: layers of bars you arrange. Boromlia starts from the events. Each holds a date or a range and can carry a place with real coordinates, a source, the people involved, tags, rich text and photos, and every view is drawn from that. The Spans style is the closest thing to a layered chart; the Map, River and Cards styles show the same events in ways a chart cannot.

Moving from Preceden to Boromlia

• In Preceden, export your timeline as CSV.
• In Boromlia, create a timeline and choose Add multiple from a file. Importing is on Advanced.
• Match the columns once: start date to When, end date to Ends, and any grouping column to Chapter or Tags.
• Check every row in the preview, then import. Photos never come in from a file, so add them afterwards, and add places too if the file had no coordinates.

Questions

Can I move a Preceden timeline into Boromlia?

Yes, through CSV. Preceden exports CSV, and the Advanced plan imports it with a preview of every row before anything is saved. The steps are listed above.

Does Boromlia draw a layered timeline?

The Spans style is the closest shape. Start-and-end events become bars on one shared axis, with single dates on the same axis, so overlapping work is visible against the decisions that affected it.

Is Boromlia cheaper than Preceden?

It depends on how you pay. Preceden’s paid plans are reported from $12 a month, and Boromlia’s Advanced is also $12 a month. The difference is that Boromlia also sells extra timelines of up to 50 events at $2.99 each, and everything Advanced has for $49.99 once, so you never have to subscribe.
