OmniCalc

This is the best free calculator out there. The developer continually updates it and I am glad it is still available. It has enough features for a casual user. If you turn the orientation horizontally, it turns to a scientific mode which will satisfy advanced users. Recommended 5/5.

Looks can be deceptive but make no mistake, this is a very powerful calculator. The unsophisticated graphics are quickly forgotten after one begins to realise just how powerful this thing is. And with its 100 x 100 registry matrix, it can match a small spreadsheet for basic data analysis and manipulation. The interface and operation is not exactly intuitive and I'm writing this with plenty left to explore, so it was a huge relief to find a comprehensive guide called 'Help' which I suggest is likely to be essential reading for others too! There's a choice of rather uninspiring colour schemes - my preference being 'Peace' - but several different and mostly very good fonts for the readout is really nice - and an unexpected bonus. If I could have one wish though, it would be for all of the buttons to be on screen in landscape orientation. It was only when reading the guide and selecting 'Scientific (iPad)' for portrait mode, that I realised what I was missing! Unfortunately, 'Scientific (iPad)' for landscape mode does not render correctly, leaving several essential buttons completely off screen. The overall feeling is that this app has excellent potential but has been left as a slightly unfinished project.

This is just brilliant So very simple to use The memory functions and the calculation storage facility Marvellous.Can't speak highly enough of this app Help facility very good. Thank you.

The 4.2 update is still broken!!!! Please fix it or I'll have to delete it and that would be a shame!

Ok, this looked promising. A decent sized calculator. Nice and bright. Functional. But flawed ... Using 4.3 it corrupts the screen when you come back from the controls page. Hope they fix it soon.

I could find no 'Contact Us' on this page nor the Jellyfilled web site. I installed and deleted this app several times. The reason? Each time that I returned from 'Controls' to 'Calculator' I get a black screen. Does this mean that OmniCalc is affected by update to the latest iPod OS? This is a pity. It looks as thought it could be very useful.

A simple, well presented and thoroughly effective app. Since downloading it I have found it absolutely indispensable.

Excellent. Clear & well set out, thanks.

Love the way I can change values with instant results and mix date math

I was looking for a calculator for my iPad and found OmniCalc. This calculator works great on my iPad. I was surprised how many options there were for customizing this calculator. The setup was quick and simple allowing me to get the look and function I wanted. My thanks to the developer for a simple to use calculator that works great. Job well done!
