Long time favorite calculator & unit converter

I use this app daily for calculations and converting units. It’s interesting that I tried this app years ago, and it has always stuck as my favorite calculator. I’ll try something else every now and again, and I just come back to this one. Across several phones, any expression that I’ve not deleted from my history has safely followed me.

I’ve done annual inventory at a manufacturing plant several years in a row in this app, and it’s invaluable—and when I found I needed to convert an unfamiliar unit a couple days ago, the tool I needed was already in my pocket. So I felt obligated to give a review, considering the ridiculous value of this app. Maybe other calculators offer similar function, but this has the vital virtue to my workflow of feeling like a better instance of a stock application.

Save your sanity

I really wanted to love this calculator... I really did. I gave it more than a fair shot and it let me down. The interface is beautiful and functional however, that is where the positivity towards this app stops. Loading times are stupid... why does a calculator have a 15 second loading time... really!? Also, there seems to be no other way to clear a calculation other than holding down the backspace button for an indeterminate amount of time. Ok ok... I can totally understand the whole holding down the backspace button to clear... the problem is that the app gives you no indication that the calculation has actually been cleared until you lift your finger off the button. Do you need to hold the button for 2 seconds? 5 seconds? Who knows. This causes a situation where clearing works consistently only half of the time. I don’t know... this calculator could be so much BETTER but it’s almost like the developers only did half their jobs on this one. Maybe laziness? Maybe someone got fired during development? Who knows... all I know is you should save your money ok this one folks. Many other better calculator apps out there. Personally, Solve is my go-to calculator app. You should definitely check out that app and leave this one in the dust.

Not just a calculator

The Calcbot 2 is the best. It converts everything. Money in different currencies compared to your country or any country. Then measuring in units or volumes. Metric conversions from metric to any other measurement such as inches. Then there is temperatures from Fahrenheit to Celsius. Any conversion is possible with this fantastic gem.
You can change the face of the calculator/ device depending which one you like.
Oh yeah almost forgot, it’s a calculator. Not just a calculator but a really good one. It has a memory ribbon that lets you see the prior calculations.
Try the free version. And if you like it then buy the full version.
Hope this helped someone.
