How to choose a travel budget app

Most travel budget apps look similar in App Store screenshots. The differences show up a few days in, once the novelty has worn off and you are deciding whether logging a four dollar coffee is worth the effort.

We build one of these, so read it with that in mind. The checklist points at competitors in several places.

The day three test

Most people stop using these apps for the same reason: logging starts to feel like more effort than it is worth. A half-tracked trip is worse than none, because the total looks real but is not.

So the useful question is not which app has the most features, but which one you will still be using in week two. Most of the checks below are a proxy for that.

Eight things that decide it

1. Taps from open to logged

Count them. Open, amount, category, save is about four. If an app wants a merchant, a payment method, a location and a photo before it accepts an entry, the reports will not make up for it.

2. Whether it works with no signal

You will be logging things on planes, on night buses, in basements and in countries where you did not buy a SIM. An app that needs a connection to save an expense, or that shows a spinner where your budget should be, is the wrong tool for travel specifically.

Test this properly: turn on Airplane Mode and try to add an expense, open the stats, and run an export.

3. How it handles currency

Three things to check. Does it keep the original amount as well as the converted one? Does it use the rate for the date of the expense rather than today's? Can you override a rate by hand when you need to match a statement?

Ask also where the rates come from. Published central bank rates are checkable. An unattributed rate is not.

4. Whether it separates country from currency

This matters on a multi-country trip. You can pay in euros across several countries, in US dollars in places that do not use them, and you can re-enter a country you already visited. An app that ties currency to country will get in the way at the second border.

5. What happens to prepaid costs

A flight bought in March and a five night hotel paid on arrival both break a naive daily budget. Look for the ability to exclude an expense from the daily allowance while keeping it in the trip total, and the ability to split a booking evenly across the days it covers. Without both, your daily numbers are fiction.

6. Whether the export is free and complete

Export is the exit. Check you can get a full CSV or JSON out, and that it carries the original amounts and rates rather than only the converted totals. An app you cannot leave is one you should think harder about joining.

7. What it collects about you

Check the privacy label on the App Store listing. A travel budget records where you were, when, and what you spent. If an app collects advertising identifiers and links analytics to a user ID, decide whether the features are worth that.

8. Whether it does the job you have

Group settle-up and personal tracking are different products. Apps that promise both usually treat the second as a side effect of the first, which is why a group app can tell you that you owe Sam forty dollars but not what your trip cost you. The difference is worth understanding before you pick.

How to test one in ten minutes

1. Install it and create a trip. Time it. Over two minutes is a bad sign.
2. Log five expenses in a foreign currency. Count the taps on the fifth.
3. Turn on Airplane Mode. Log another one. Open the stats.
4. Add a prepaid hotel and try to spread it across four nights.
5. Try to export. See whether it asks for money.
6. Change your home currency and check the old entries kept their original amounts.

Ten minutes before you leave is worth more than finding out in week two.

Which kind of app you need

• Group trip with a settle up. You want a splitting app. Everything else is secondary, and the group being on mixed platforms decides it.
• Your own spending, one trip. A personal travel tracker. Fast entry, daily allowance, multi-currency, offline.
• Year-round personal finance. A general budgeting app with monthly categories. These are poor at trips because a trip is not a month, but good at the rest of your life.
• Work travel to be reimbursed. Whatever your employer's system accepts. The important feature is the export format, not the app.

Red flags

• No way to get your own data out without paying
• Rates with no stated source, or no rate date stored on the expense
• An account required before you can log a single expense
• Daily limits on the free tier, which surface exactly when a trip gets busy
• A dashboard on the home screen instead of the one number you need before ordering
• No way to exclude a prepaid cost from the daily budget
