color - Is there any low cost way to Calibrate my display?

I'm using Apple cinema display model number A1316 27 inches. I think it is from 2010.

I'm making User Interface for mobile app and we also plan to make some marketing collateral (some printed brochurse and packaging etc.)

Should I calibrate my cinema display (it has never been calibrate before)? if I should, should I use X-Rite ColorMunki Display (http://www.xrite.com/colormunki-display) or I should go for X-Rite i1 (https://www.xrite.com/i1solutions-color-management). I do not have much money will X-rite ColorMunki Display be sufficient enough for my work?

Or is there other brand or product that is better and cheaper than these product?

is the spectracal brand also suitable for my work which model? The Datacolor S5X100 Spyder5EXPRESS also interesting. Which one to choose?

Answer

Yes you should calibrate, always.

As for what calibration hardware to use, that's largely a matter of preferences. But any calibration hardware is better than none. You really can't go terribly wrong with any of them.

I use the Xrite i1, but that's just my preference.
