Yep, we do have one in the works called MoneyBug, but work on CheckBook 2.5 must be completed first in order for MoneyBug to sync with it. We are busy splitting out major features of 2.5 into subsequent updates to keep 2.5 from getting too large. 2.2 was released with major overhauls to splits, and 2.3 will have some major tweaks to our reconciliation, leaving 2.5 with a database update and syncing as its major feature.

Thanks for the interest and forum post!

Sadly, MoneyBug had to be shelved awhile back for a number of reasons, but we're hoping to revisit the idea of developing a mobile version of CheckBook (Pro) in the near future.
