Makes this app useless to me without converting my data to MM then back to inches. Developer-how about a decimal option for fractions? Even programming was more complicated to only be useful for carpenters! **Developer response:** I will fix it soon ### 1/5 — Very disappointing *2023-10-28* Adds cover the top of app and you can’t change from fractions to decimal. Nice app terrible add placement. ### 5/5 — Nice app *2022-07-14* Straightforward does what he supposed to do **Developer response:** In the next update fractions will be added ### 4/5 — A useful App, nicely presented *2020-09-01* Update 01-Sep-2020 : Thank you for the very civil response. The App functions quite adequately with the Ads displayed but, as a matter of principle, I am upgrading at your new reduced price ... and I hope other users will follow my example, to encourage further development. One feature I would like to see, if you can: It would be helpful if the diagram changed to match the calculated results. [Original Comment] But the price to remove Ads seems a little excessive **Developer response:** Dear Sir, I will change the price. you are welcome ## Frequently asked questions about Arc+ ### What dimensions can Arc+ calculate?
