Common questions
Do you see my card or bank data?
No. Kartmetre has no server and never connects to your bank. What you enter stays on your phone, encrypted.
Why does it say "estimated"?
Banks calculate interest and due dates in slightly different ways. Enter the figures from your statement and Kartmetre uses them instead.
What happens if I change phones?
Export your data from Settings, or with Pro turn on the encrypted automatic backup, which travels with your iCloud or Google backup and opens with your password.
