Most currency apps stop at rates and one-off conversion. Currency Trip is a travel calculator kit: convert many currencies at once, pick two and watch amounts flip in real time, split tips by people and percent, and log trip spending with both local and home-currency amounts. Scan a price tag to see it in your currency, and apply real desk or card rates per screen. On Android, open conversion or price scan from the lock screen—so you calculate on the spot, without digging for the app.
