This universal version works with both iPhone and iPad. The iPad version features a full sized (1:1) keypad with TypeTone, a unique audio aid to help guide your finger back to the center of a key. The total (*) key (iPad or iPhone) can be on either the left or right side (Sharp or Canon style). Also. Review & edit numbers, add or delete lines. Save & retrieve paper tape files. Export paper tape files to iBooks©, Dropbox©, or your favorite printing utility (see the FAQs). ==== Recent Press ===== Has been featured in iTunes "What's Hot" in the Finance Category.

Both calculators are single-column adding machines or calculators with full-size (1:1) keypads and are optimized for the iPad User Interface.

Touch any line of the paper tape for edit mode. Touch the side controls: Add Line, Delete Line. You can also edit numbers, split Add/Sub or Mul/Div groups. Press Done to return to Calculator mode.
