Help & support
Frequently asked questions
Does it work offline?
Yes. Prices are read and converted on your phone; the internet is used only to refresh exchange rates. Without a connection the app uses its latest rates, and the time of the rate is always on screen.
Which currencies are supported?
Nearly every currency in circulation. The currency of a price is taken from the “source currency” you choose or the one suggested from your time zone; if the label shows an explicit symbol or code, that one applies to that price.
Where do my images go?
Nowhere. Camera images never leave your device, are never saved and never shared. Details are in the privacy policy.
How often are rates updated?
Rates are the European Central Bank’s mid-market rates, published once per business day. The app refreshes them by itself when you are online. Results are shown with “≈” because banks and cards usually add a margin on top of this rate.
Do I need an account?
No. There is no account and no sign-in.
Why are the results approximate?
Reading a label and converting a price involve estimates: a reading can be wrong, the rate may be a little old, and your bank’s rate at payment time may differ. For the exact amount, tap the price, open its detail and correct it if needed.
Troubleshooting
The camera is black or says “Camera is not available”
- Check the camera permission: your phone’s Settings app › Ederi › Camera.
- Another app (a video call, for instance) may be using the camera; close it.
- If your iPhone is mirrored to a Mac (iPhone Mirroring), the camera is unavailable; stop the mirroring.
- Quit the app completely and open it again.
No price is found
- Move a little closer; the digits should be sharp and large enough on screen.
- In low light, turn on the flashlight (top-right button).
- Hold the phone still for a moment, then tap “Pause” to freeze the frame and look at it calmly.
- If no source currency is selected, tap the currency pair at the top and choose the currency of the prices.
A price was read wrong
Tap the chip or the card at the bottom; on the detail page you can pick an alternative reading or type the amount with “Correct”. The correction shows on the chip and in the history at once.
The currency is wrong
The currency pair at the top (“EUR → TRY”) shows the setup: the currency of the prices on the left, yours on the right. Tap it to change either. If the label shows a different currency, the app marks that price with a badge.
Rates look old
The rate line shows the age of the rate; after seven days a warning band appears. Go online and wait a moment; rates refresh quietly. Converting keeps working meanwhile.
Deleting history
In the History screen, swipe a row to the left and tap “Delete”, or choose “Clear history” from the menu at the top right. The same option is under Settings › Data.
