Notice the charges that deserve a second look.

A small change can be easy to miss

A service you usually pay $115 for suddenly costs $151. Cayn can highlight the increase and put the previous charges beside it, giving you the context to decide whether to look into it.

It can also flag potentially avoidable transaction fees. A flagged fee is a starting point for review; Cayn does not promise a refund or automatically change your bank account.

See what needs your attention

  • Recurring bills that have increased.
