Numerus iPhone Utilities App Review

Posted on 13. Jun, 2009 by iPhone App Reviewer in $2, 9 Star Ratings, iPhone Utilities App Reviews

Numerus: An amazing scientific calculator right on your iPhone

Version Reviewed: 1.0.1
Developer: Balazs Faludi
Price as of Review: $1.99
Current iTunes Rating: 4.5/5

Numerus is exactly the app we need on the iPhone, it’s the best utility application I have ever used (and I use it almost every day).  Although the iPhone has a calculator it’s features are limited and even in landscape mode it doesn’t compare to a real scientific calculator.  Numerus can handle advanced equations and packs a large variety of features and functions in it’s small package.  The app allows you to save all your previous calculations as well as email them.  You can store variable data and call them in all the mathematical functions it provides (just look at the screenshots here).  It’s highly stable and the calculations are always correct, I haven’t found a flaw in any of the functions, and have never had a crashing issue or glitches.

The user interface performs just like a real calculator, and there’s plenty of room to view your calculation, not to mention a great advantage of Numerus’ view area is that you can compute large numbers (over 10 digits) with ease.  It provides a 2nd function button which unlocks a whole host of new abilities.  Unfortunately it cannot rotate into landscape mode, a lot of people I’ve demoed the app to have noted and disliked the lack of mulitple viewing angles.  Even if you’re not going to use advanced functions Numerus still beats the iPhone’s default calculator by far, it allows you do to long calculations with brackets, exponenents, and all standard operations (*/+-).

All in all Numerus is a great application to have on hand and should be on every student’s iPhone.  I won’t leave to school without it!

Final Ratings:

Usefulness: 9.6/10 – The perfect scientific calculator, a few more feautres like graphing and it could replace an entire set of non-iPhone mathematical tools.

User Interface: 8/10 – Flawless but unfortunately does not have a landscape mode!

Price: 8/10 – Absolutely cannot argue with the two dollar price, obviously beats a real scientific calculators cost too

Technology: 8.5/10 – I haven’t experienced a single glitch or mathematical flaw, again though, no landscape mode.

Execution of Concept: 9.8/10 – You couldn’t expect any more from the developer, it’s an absolute programming masterpiece

Overall Rating: 9.3/10 – Average is 8.8 but I’m giving a 0.5 bonus point!

Further Improvements:

• Landscape Mode
• Quick access feature allowing simple quick equations
• Expression/Equation simplyfing ability
