I originally designed this app because I found myself at yard sales and finding great deals on tanks but the owner had no clue on the actual size of the tank. I found myself wishing I had a pocket aquarium calculator. I installed it as a beta for a few friends devices and they convinced me to add a other tank formulas and units of measure used in other countries to the app and release it to the community. I have since been using it while designing sumps.

So Enjoy:

iTank Calc



iTank Calc v 1.0 is a feature rich FREE calculator for the iPhone and iPod Touch that is used to determine the volume of an aquarium by entering a few simple measurements.

Each calculator has been coded with the user in mind. Use it to find the volume of an existing aquarium or for one you are building.

Features
- Easy to use user interface
- Calculate Rectangle/Cube. Cylinder, and hexagon tanks
- Easy touch screen keyboard
- Each output is rounded to the nearest hundredth ie. 25.54 US gallons
- Returns answers in U.S Gallons, UK Gallons or Liters
- Help page with a diagram for each calculator for reference when measuring
- In app support and suggestions email links
- IOS 4.0+ compatible

Screenshots









If this app the app does well and I get some email feedback I will implement some addition things to including:

More tank shapes
More features


I won't add a link to it but those of you with an supported can get it from the app store just search iTank Calc.


Comments and suggestions appreciated Razz[/b]

New version in store now. v 1.0.1

Update includes:
Minor bug fixed to autohide keyboard when Help is pressed
Now compatible with 4.0, 4.0.1, 4.0.2 as well as 4.1
Added Keyboard autohide to clear buttons
Optimized coding to improve view switches while maintaining low memory usage (should switch faster and use same to do it ram)


I am working on the bow tank calc now and it is giving me a few problems. I hope to have them sorted in the next few days. If all goes well this will be a VERY VERY accurate bow front calculator. In fact I have not seen one even online that is doing it this way which makes them less accurate.

I wanted to give you a little sneak peek of what is coming in v1.1

The Bow front Calculator

Now I believe that this bow front calculator is the most accurate one of its kind. I have yet to confirm this so its not set it stone. (My formula is being sent to a mathematician and he will let me know its degree of accuracy for sure)

BUT, what I can tell you is that all the ones I have seen online. DO NOT do it the way iTank does it. And most of them say that they are returning approximate values and rounding numbers making them inaccurate to some degree. iTank takes a different approach and returns a value that is FAR closer to the actual size of the bow front tank.

I have tested this on a site that has a bow front calculator after entering my values was returning 100 gallons. I entered the same values in iTank and it returned 102.61 Gallons.

After it is checked I will know for sure.


It will still be 2 weeks or so until this is available as I still have to finish some additional updates.
I will let you all know when it is ready for download Smile

Just out of interest - you still need the actual size of the tank ie. the measurements to use your App so why would you need it?

If I buy a tank it is by dimension not volume as it need to fit in my vehicle or in my home.


Have you accounted for glass thickness?

In your head could you please tell me what a cylinder tank would hold with a depth of 48 CM and a diameter of 24 CM in Liters?

Or better yet One that requires geometry and trigonometry functions.
A bow front tank that measures 60" Long, Has a Center Width of 22", A side width of 12" and a depth of 21" in UK gallons.

iTank does both of these with precision. It is a tool.

Maybe I don't understand this statement.

There are many reasons why someone would want to know the volume of their tank.
To name a few:

If you want to treat the water you need to know how much to add. That could be dosing, medication, ect.

If your going to do a water change of 10% how would you know how much to change without knowing how big your tank is?

If you would like to buy a new pump for your tank, how could you select one that would turn the tank water over a certain amount of times per hour if you don't know how much water your dealing with?

Certainly there is plenty more reasons the you should know the volume of your tank. so again Maybe I don't understand what you are getting at.

Most people do buy tanks that will fit in a certain area. That does not mean that they don't want to know how much water the tank holds.

When measuring the volume of ANY container to get the most precise measurement all measurements should be taken as inside dimensions. Which eliminates the need to worry about wall thickness.

Then you may want to add a function that accounts for displacement of at least inches x amount of inches of substrate in different dimensions. Hard to account for decor as it varies so greatly in shape and size, but at least accounting for substrate would be nice.

A cylinder 48cm high and 24cm across is not a tank it is a vase and off the top of my head the bowfront would be about 75 Uk gallons.

The answer would be 21.71 Liters.

85.44 UK gallons would have been the correct answer.

No it wouldn't.

It would be about the the total volume (just under 85 gallons for a thin commercial tank - no one uses internal dimensions) but no allowance for header space or non water contents.

I worked out 75 gallons by simply averaging the side & middle widths to mentally calculate a box volume.
It is easy with practice.
