Frequently asked questions

A daily budget for long trips. You set one budget for the whole trip and your route, and Trailbudget gives you a target for each day, with more for pricier countries. Log what you spend and the days ahead adjust.

Yes. There are no ads and no in-app purchases.

Not yet. Trailbudget is for iPhone (iOS 18 and later).

No. Everything works without one, offline, with your trips saved on your iPhone. Sign in only if you want a backup you can restore on a new phone, or to split costs with a travel buddy.

Yes. Logging, targets, widgets and reminders all work offline. Exchange rates refresh when you’re connected, and saved rates keep working in between. Without any saved rate, you can enter what something cost in pounds.

Your everyday money (the budget minus flights and other big costs) is shared across the days left, weighted by each country’s typical daily cost. Today’s target is fixed once the day starts. Spend more or less and the remaining days share the difference.

From published budget-traveller benchmarks, with the source and the date they were checked. They set each country’s share of your budget, not how much you must spend. You can edit any guide.

Turn on Split over several days when you add it. The cost is shared across the days it covers, so one day doesn’t look far over and the rest suspiciously cheap.

Budgets are in pounds (GBP). You can log costs in any currency; each is converted at that day’s rate, and you can enter the exact amount your card charged instead.

Unlogged days keep their target held until you fill them in, so they don’t look like free money. Today shows a catch-up row with one tap into the missed day.

A way to split costs with someone you travel with. When you add an expense, turn on Split with…, choose who paid and how it’s divided. Only your share counts on your trip; your buddy gets theirs to add to their own trip.

Yes. Buddies link people, not trips. Each of you keeps your own trips and budget, and a shared cost goes on whichever of your buddy’s trips covers its dates. If none does, they pick a day.

No. They only see the costs you choose to split with them, plus the name you choose to show.

No. It waits for you under Shared with you, showing your share and which trip it goes on. Add it, or tap Not mine. If your buddy changes or removes it later, you’re asked before anything changes.

Settings → Travel buddies → Invite a travel buddy, then send the link however you like: WhatsApp, Messenger, Messages, email. It opens Trailbudget if they have it, or shows the code and where to get the app. They can also type the code under I have a code. Both of you need to sign in.

No. It keeps a running balance (“Sam owes you £60”) and lets you record when you settle up. Pay each other however you normally would.

On your iPhone. If you sign in, a backup copy is kept on our server in Helsinki, Finland, with encrypted nightly backups in Ireland. See the privacy policy for the details.

Sign in on your old phone (Settings → Backup) and let it back up. On the new phone, choose Restore from a backup on the welcome screen and sign in with the same account.

Different trips sync without asking. If the same trip changed on both, Trailbudget shows both versions and asks which to keep. Earlier copies are kept on the server so a wrong choice can be undone.

Settings → Backup → Delete account. It deletes your account, backups, buddies and shared costs from our server. Your trips stay on your iPhone.
