Horrible replacement for convertbot

I had purchased convertbot and just restored my phone when upgrading to ios9 and noticed it was no longer on my phone or available in the App Store. This is a terrible replacement that makes conversions a hassle. Why did you kill convertbot? This is basically a calculator app that threw conversions in as an after thought. VERY disappointed and not not ever support this developer again.

As a side note to any other unhappy convertbot users that lost convertbot I was able to fine it on my iTunes backup and the app works perfectly fine on ios9. Not sure why the developer made the decision to pull convertbot from tha App Store when it works just fine and could be a continued revenue stream for them. Anyway look to your iTunes and you might be lucky and able to get back the app that works great for conversions.

This review is solely for the Watch app...

... Seeing as I only use it on the Watch. The app is flawless. I thoroughly enjoy the usage of the hard press and I love the entire thing.

One problem: I need to be able to access the app in "glances". I use calculators on a daily basis and need quick access. At this point, it's quicker to pull out my phone and use the Apple-native calculator app than it is to go to the Watch home screen, zoom in enough to see the apps and click the Calcbot app. Update the Watch app with "glances" integration and you'll get 5-stars from me in a second.

Fix it

Gave it a 5-star review previously, optimistically thinking they might address the glaring conversion flow problems. Unfortunately the problems have persisted for a while, so thus it becomes the entire review:

Please make it easier to edit the input when in conversion/units mode. It seems you can only change the amount (or use the calc etc.) if you completely exit the conversion mode. It'd be good to be able to select a conversion, pin it somewhere on the main calc display, and continue doing calculations while always seeing the converted result.

More people should 1-star this thing until it's fixed.
