Currency doesn’t update anymore

For the past week the currency will not update anymore

Serious error

For two days now the currency (dollar rates) have been way out.
Used to be a brill app.

Had the potential but failed

This converter is missing fundamental ways to calculate and convert units between standards. Such as you can’t input 5’10” to cm’s, it only gives you the option for feet or inches and a decimal place, which won’t work with imperial measurements.
You missed the bar unfortunately.

Helpful but needs to make user friendly

Too many steps to convert grams to pounds and ounces. Faster to use my iPhone calculator.

Great app

Great free app. I’ve been using it for years.

Great app

Love this app! May need a few tweeks for stability. Tends to crash allot. But its usefulness out ways the hassle. If more stable, id give it 5 stars.

Really useful

I have been using the iPhone since the first model was released, and this app is one of the first I installed when the App Store opened to third party developers. I've consistently used it since then, and over the years it's become the only app I use for any conversions. Currency is great for travel and online shopping, and all the other conversions will come in handy at the most unexpected times. It's also useful to have the ruler for getting a rough idea of size. (I'm not good at visualizing 3", for example.)

This app had some technical issues a while back, but they seem to be resolved. Despite this app not having an update since 2015, it still works great on my 6S+ running the most current OS. I hope the developer hasn't abandoned the app, because I've never found one that's so simple, comprehensive and affordable. I'm keeping my fingers crossed that they'll come back if needed. Until the app is definitely abandoned and no longer working, I highly recommend this app. It's been on the main screen of every single iPhone I've owned

Very useful

It has worked great for me whenever I needed a conversion!

Handy app

Never had any problems with it. Has many features and you're able to edit the list of what you want it to convert to.

Astronomical Units

Please add solar mass to the weight/mass category. I suspect other astronomical units are also missing, so please go through it and make sure they are there.
