But the ruler function is in accurate for the modern iPhones.

This app was great and still mostly is, but it really needs an update as some conversions like currency are a little off. Wish this app was still maintained!

I’ve had this on my phones for years now - always on Home Screen and quickly available. It can’t get much better since the ability to reorder/edit conversions list. BUT, I just discovered I can’t find the unit “grains” in UNITS. Argh! Who knew that archery arrow components are pretty much all described in Gr ?!! Not me! Please add that unit (1gr = 64.79691mg) to the coverage. Thx - Jack (retired chemist) 👍

What’s not to like here? This app delivers exactly as represented. Determine the category (Ie ‘Liquid volume’ then enter the value you wish expressed in the variety of unit types. Perfect!

For years, I really liked this app and then the currency section went dead. Then, I retried it a month ago and, voila, it all works great again.

Used Units Premium for several years and liked the product. That said just noticed currency exchange rates ate not being updated : Unfortunately looks like product is dead since neither support form or developers contact link works any more ...

I payed a doodle for the premium and there is no Apple watch app for it but other than that it is good

I find this program very easy to use and very quick. I only only to enter one unit and all conversions take place simultaneously. I enter in one yard and instantly I know how many parsecs it is as well as how many parts of the earths diameter. Do you want meters, inches, cubits? It’s all there with just one entry. I don’t know what could be simpler. No flash, no sound effects, just results. It’s unencumbered by distractions. It satisfies curiosity. Handy and educational. It lacks one feature that none of the converter apps have which is the ability to enter in my own units. No matter how many conversions an app has, there are always some arcane measures not included. Do any of them include a megalithic yard, for instance? Not that I know of. (2.72 feet) or a day’s journey? (34 miles) How about 366 degrees in a circle based on sidereal time? Minoan foot anyone? I can’t expect an app to have everything but I would like the ability to add what I want.

While the application does function on a basic level, the developer seems to have “abandoned” it. No updates in over two years, and there’s no support (website is dead) for the app. The “Currency” conversion is essentially useless, because it seems to have stopped updating the exchange rates; mine are seven months old.

I used to love this app to update me international currency when i go abroad . I used to have the free app. I was thinking if I use the paid app, foreign currency might update . I bought then tried it. Still wouldn't update .
