Watch app not working

Watch app opening then goes black. Tried to contact developer but gives me an error. Will update stars if this gets fixed. Purchased Burke to support developer but not happy when I got to use on my watch

Response from developer

Hi Tay Sorry, I'm aware of that issue and will try to fix it when I can.

Easy to use

Have it installed on my phone for many years now, though only used it a handful of times since it launches but glad to see the developer still updating it and it does come in handy when I needed it. The app look much more modern then before and is still easy to use. Thanks for still keeping it updated

Response from developer

Thanks. I use it myself, so I keep it updated!

Clean and nice

Fast calculation and saves time.

Vector math made easy

Easy enough to calculate toric over refraction in front of the patient.

Great app for a quick confirmation off the lens to order

Works well

A great app

Very useful app for determining resultant cylinder Rx on toric lenses. I use this feature frequently.

Two thumbs up

Perfect contact lens app for getting a starting point on a new contact lens fit. Developer was very easy to contact and answered all my questions in a timely manner. Highly recommend.

Works Great.

Does what it promises. No, it doesn't convert to plus cyl, but is it really so difficult to do that math?

OD

I mostly work in plus cyl. The calculator should be able to transpose to minus cyl much like the ToriTrack program available from CooperVision.

It Calculates Toric O'Rx

Easy to use. Works.

Update fixed problem I had (I omitted to change my rating)

The update appears to have fixed all the problems and more flexible. Great app to help fitting torics
