Worth knowing before you sign up
- The iOS app costs $24.99 as a one-time purchase, not a subscription. That revenue funds the free versions on every other platform.
- The Android app is built by a separate team and is free.
- The interface is frequently described as dated and the learning curve as steep.
- The real cost is the time spent building and maintaining your own cards.
