The Date & Time Calculator with Math Expressions Evaluator app is a straight-forward no-nonsense app to get the sum and convert a series of numbers and/or time expressions.

The Math Expression calculator built-in to the app features a text box for entering in your arithmetic as well as trig and log functions to be solved at the bottom of the screen. Search and replace functionality is designed to make it easier to update the input at the top of the screen.

The time calculator calculator functions as an old style tape calculator. As the numbers are added to the list as positive or negative values, the result is automatically generated and a history list is immediately updated and allows deletion of any row in the list.

Example – using the Days:Hours:Minutes:Seconds – format

Accumulated Times:
1:08:03:00
-0:05:06:00
-0:09:00:00

Calculated Time:
0:17:57:00

Time Expressions of time are entered in the D:HH:MM:SS format, and the touch interface of the iPhone/iPad/iPod Touch allows you to skip to the time unit of your choice or press the colon key to skip to the entry point using the convenient onscreen keypad for the best interactive application of problem.

The answers are presented in both US units and metric. The surface area is top the of your aquarium is where the oxygen diffuses into the water. The volume is the maximum amount of water in inches or centimeters as well as gallons or liters the aquarium can hold. The weight is in US pounds or kilograms as the calculated amount of water plus salinity. Salinity defaults to 1.0, but it can be changed and saved per calculation.

The types of aquariums supported are

Additionally, there is are the following Converters

1. Area
2. Distance
3. Flow Rate
4. Imperial/US Units to Metric Conversion
5. Metric to Imperial/US Units
6. Pressure Units
7. Temperature
8. Volume
9. Flow Rate (Volumetric: Gallons or Liters)

Temperature Converter for Farenheht/Celsius/Kelvin conversion and a Flow Rate Converter for converting between gallons per minute (gpm), gallons per hour (gph), liters per hour (l/hr), and liters per minute (l/min).

All results can also be emailed through the iphone’s email application using an automatically filled-in email template provided with the app.
