Highly recommended

Reluctant Lemming

I Purchased PCalc and was immediately impressed. Honestly, this app has no peer. Fully customizable, with deep and thorough functionality, it’s hard to imagine anything could be better. After trying the Lite version I jumped and purchase the additional packs and never looked back. Also, I had reason to contact PCalc with a question and they replied immediately. I was totally impressed. Thank you for a great app PCalc people!

Engineering decimal places

KJandBA

Overall, an excellent calculator app. Will award that 5th star when the Engineering Decimal Places is fixed.

Correct implementation will show the same number of significant digits as specified. The flawed implementation controls only digits after the decimal. Thus the significant digits shown is different depending on value. Very annoying. (See HP for correct approach.)

If this is all that’s wrong, then these folks have produced a top quality product. Hope y’all fix it!

A terrific calculator!

There seems no end to the design wisdom built into this little app. I own several of the add-ons to PCalc Lite and am delighted with the way it functions, including its customizability. Fresh dated currency conversions among numerous other conversions and reverse notation (hp12c style) are just two of the best features, though certainly not close to all! Highly recommended!

Developer Response

If you have purchased the Power User Pack, there is an option in the Advanced settings called Clear on Open. Turning that option off should do the trick. If it doesn't, please send an email to pcalc@dragthing.com so we try to solve this.
