Not so Outstanding


A very important feature is missing: SYNCRONIZATION of the currencies. I’ve reinstalled mine several times and the last sync date unchangeable is December 12th 2016. Today is March 12th 2018. Even when you touch the cycled update button on the top of the app screen, it remains the same and a prompt says “updated successfully”, wrongly, and that date does’t change at all.
Ah, Yahoo and Google converters don’t work at all, and the default one stopped on the mentioned date.
How to update it?
Worse, no way to insert the currency value manually. You need the official and also the parallel cotation to buy a currency in the black market, so you have to edit its value. How to do it?
Sure, except these issues, Hicalc Pro is very good with many other features, even the extra bought ones. It works also on RPN.
Of course, there must be also automatic syncing. However, as illustration, RLM-Fin-CX app also lets you change currency cotation manually. Check it out!

In advance, the HiCalc HD app, for iPad, has the same issues. The last currency sync date on that app: December 12th 2016. Unbelievable!

My device: iPhone X, 2018 all updated.

Please fix them !
