A buy-once passport photo app like Snapport has no per-photo cost after the initial purchase, making it cheaper than per-use alternatives or visiting a pharmacy for multiple passport renewals.
G+Money Lite is free and covers the core case: logging expenses in multiple currencies on a trip. The paid G+Money adds offline exchange rates and more detailed reporting.
Travel documents — passports, visa scans, hotel receipts — often contain sensitive information. Apps that sync to their own cloud add a data breach risk. Offline-only apps keep this data on your device.
