Things people ask
The rate looks wrong
Every currency figure in the app carries a line under it saying where the rate came from and how old it is: live, cached, built-in, or one you set. If it says built-in, the app has never reached the network — the number is from the table compiled into the app and could be months old. Open Settings to refresh, or set the rate by hand and yours will always win.
A tile disappeared
The board hides readings that cannot be what you meant — nobody types 1,500 and means degrees. When anything is held back, a Show N more control appears on the "Other" line. If you would rather nothing ever moved, Settings → What doesn't make sense → Dim keeps every tile in place and simply fades the ones that do not apply.
My number vanished
That is deliberate. Two minutes after you put the phone away, the typed number is cleared — a price you typed before your pocket is one you have walked away from, and a stale figure over the keypad looks like an answer to whatever you are holding now.
It opened on the wrong country
The app takes one location fix per launch. If you declined the location permission, it opens where you left it instead. Turn it on in iOS Settings → Convert Once → Location, or just swipe to the country you want.
How do I remove a country or a clock?
Swipe the row to the left, in either list, and tap the bin. The last country cannot be removed — the app would have nothing to show.
Can I get my shoe size in men's rather than women's?
Settings → Shoes. You can also choose which system you read sizes in.
Is my location sent anywhere?
No. It is turned into a country code on the device and thrown away. See Privacy.
Refunds
Purchases go through Apple, so refunds do too — request one at reportaproblem.apple.com. Do tell us what went wrong as well; we would rather fix it.
Something else
support@convertonce.com for problems, hello@convertonce.com for anything else — including a country whose tipping note you think is wrong. Those are the corrections we most want.
