Itinerary apps, what actually matters

The test that matters

Almost all evaluation of itinerary apps happens while planning, sitting at a laptop, with a good connection and plenty of time. Almost all use happens on a phone, on the third morning, in a hurry, on hotel wifi.

The right test is: on day four, standing on a street, can somebody who did not build the plan find out what is next in under ten seconds? If not, the app has failed regardless of how good the planning experience was.

Geography is the point

An itinerary is fundamentally a geographic problem. The reason a plan works or does not is whether consecutive items are near each other.

That means a map view is not a nice extra, it is the primary way to see whether a day is sane. A list of five things in a city tells you nothing about whether the day involves crossing town three times.

What to look for: the whole day plotted at once, walking and transit times between consecutive items, and the ability to reorder by dragging on the map rather than in a list.

The most common planning error, a day that zigzags across a city, is invisible in a list and obvious on a map.

• Whole day plotted on one map
• Travel time shown between consecutive items
• Reordering that updates the map immediately
• A warning when two items are far apart

Time blocks versus exact times

Most trips do not run to a timetable, and an itinerary with a 10:15 slot for a museum creates a feeling of failure by 10:40 on the first day.

Time blocks, morning, afternoon, evening, or loose two to three hour windows, describe how people actually travel and survive contact with reality.

Exact times are correct for a small number of things: flights, trains, ferries, timed-entry tickets, and restaurant reservations. Those are commitments. Everything else is an intention.

A good itinerary tool distinguishes between the two, so that the fixed points are unmissable and the flexible parts are visibly flexible.

Offline and connection quality

The moments you most need the plan are the moments the connection is worst: landing in a new country before a data plan activates, in a metro station, in a rural area, on the ferry.

What to check: does the app cache the current trip, does it show the plan without a connection, and does the map work offline or at least show the pins.

The fallback, which every group should do regardless: screenshot the first day, the accommodation address, and the flight details before travelling. Every system fails eventually.

Export and ownership

A plan you cannot get out of an app is at risk. Apps shut down, subscriptions lapse, and phones are lost.

What to look for: export to a calendar file, export to a shareable link or document, and the ability to print. Any of the three is enough.

Calendar export is the most useful in practice, because it puts the fixed commitments, flights, trains, and reservations, into the thing people already check every day.

Features that sound better than they are

Automatic itinerary generation with no input. Without your constraints it produces the same generic list of top attractions that any search would.

Deep integrations with booking sites. These break constantly as partners change, and a broken integration is worse than none.

Social features. Almost nobody wants to follow strangers itineraries, and the feature usually crowds out the parts of the app that matter.

Gamification and completion tracking. A trip is not a checklist and treating it as one produces the specific unpleasantness of feeling behind schedule on holiday.

• Generation without constraints produces generic results
• Booking integrations break and are hard to notice when they do
• Social feeds crowd out the plan
• Completion tracking makes a holiday feel like work

What a good day looks like in a tool

Two or three anchors, at most. One fixed commitment in the evening. Everything else as a loose block. Travel time between items visible. A map that shows the day does not zigzag.

And a note field per item, because the useful information is almost always something like: entrance is round the back, book the 09:00 slot, or Marco has the tickets.
