Best Conversion App, But...

This is the best conversion app available for iOS and MacOS X. Converter Plus has the rare ability to create new units based on existing units through a simple formula feature (no waiting on the dev to add). This alone makes it a 4-star app.

However, it heeds to catch up to its iOS counterpart which got a major overhaul over a year ago, and at the top of the list should be the addition of iCloud syncing. If I add my own conversion here, it should show up on the iOS versions as well. iCloud is a mature technology now, so this shouldn’t be a problem. The iOS app has it already (and it works great), so that lack here costs it a 5-star rating.

Still, I'm surprised that the iOS blogosphere hasn't caught on to this one. Maybe because TranCreative does its work quietly and competently but without fanfare. It’s by far the best conversion app out there.

Great Tool. Easy to use, simple, does the job and then some

Add your own conversions for units not in the library or load up what’s built in. Clean-up what’s displayed by settting you favorites or show all conversions in a given category. Great tool, worth the price. I have it on my mac, iPhone and iPad so I always have it handy.

Very useful

Since I have to check conversion rates for up to 10 currencies I find this easy to use and gives me the information instantly. There are instances that the information is not correct however. Currently the Cambodian Riel is shown as 5000 and actual 4111
