Does YenPocket work offline?
Yes. The app ships with a rate table and saves the latest daily rates on your phone. Converting, the basket and the scanner all run on the device, and rates refresh when you're back online.
Where do the exchange rates come from?
Daily reference rates from Frankfurter, which publishes European Central Bank data. Taiwan dollar and Vietnamese dong rates come from ExchangeRate-API. They are reference rates, not the rate your card or ATM will charge. Card networks and ATMs usually add their own markup.
Is YenPocket free?
The converter, basket, widgets and Apple Watch app are free. The camera scanner is an optional one-time purchase ($3.99 on the US App Store). There are no ads and no subscription.
How does the scanner know if tax is included?
Japanese price tags often show two prices: 税込 (tax included) and 税抜 (before tax). Consumption tax is 10%, or 8% for food and drink you take away. YenPocket reads the tag, shows which price you're looking at and marks totals it had to estimate.
Can it help with tax-free shopping?
The basket tracks your progress toward the tax-free minimum, counted before tax as the rules require. Whether a purchase qualifies depends on the shop, what you buy and the current rules, so check at the counter.
Are my camera images saved or uploaded?
No. The scanner uses Apple's on-device text recognition. Camera frames are read live, never saved and never sent anywhere. Only the price number is kept.
Does it work on Apple Watch?
Yes. The Watch app has a number keypad, a direction swap and Digital Crown input.
Which languages does the app support?
The app has 19 language options, including English, Japanese, Korean, Simplified and Traditional Chinese, Thai, Vietnamese, Indonesian, French, German and Spanish.
