Short answer
Offline currency apps convert using the last exchange rate stored on your device, not a live rate, so the golden rule is to refresh rates while you still have Wi-Fi before you travel. G+Money combines the two jobs: convert a price and log the expense in one action, entirely offline, using a rate you set or last updated. Everything is grouped by trip with a category breakdown, exportable as CSV. Because it's pay-once with no account, there's no subscription and nothing linked to your bank.
Try G+Money on a real example first, and check the current App Store listing for exact features and pricing before you decide.

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
