Go to Calc

I love this app because of the running tape. I can quickly see if I made a mistake. Id love to fig out at the end when I press = for the total to not double but Im sure its my not understanding. All the others are nice but I like to be able to double check.

Just About Perfect, 5/8/21

Have been breaking this in doing the budget. I just needed a good, simple calculator with a ribbon to keep track of my calculations and keep a running tally.

Very pleased and glad I purchased it. Does exactly what I need with no fuss. It also has many features I probably won’t need personally, but they will also be welcome for those who do.

Good work guys!

I love it

Great clean interface. And keeping a running tally AND the ability to print the whole thing out? Who would've thought these old school items would be so useful? Great job.
