Battery hog I accidentally opened this earlier today but immediately closed it and made sure it wasn't active in system panel. It used up 2% battery. I had my music player running for 31 min and that used 2%. I played Flappy Bird for awhile and that only took 2%. Yet, this app was open for only one second. How could it consume 2%? WTH?

## Ohm's Law

Two common calculators for electronics/electrical use:

Ohm's law calculator/Watt's Law calculator: figures any 2 unknown values given 2 known values

Resistor calculators: figures bands given value or value given bands. For 3, 4, & 5 band resistors

* Preferences/lock functions allow values to either autorange to appropriate SI units or remain fixed

* Resistor calculator automatically determines 3, 4, or 5 band

* Clean, intuitive interface

*** To the few who have commented that it's "stupid" to have the "Rate" button where it is, please stop && think. You don't HAVE to rate it before using it, nor are you even being asked to. You will notice that there are 2 buttons. This is the "About" dialog that is shown the first time you run any new version or tap the "About" menu item. Please think before you speak. Thank you. ***

## EZ VAT 2in1 for Android.

VAT's the way to do it! Most percentage calculators on the market try to show you how clever they are by cramming in loads of functions. The result - some of them are more complex than a scientific calculator!

With our EZ Toolz series, we turn this philosophy on it's head and make our calculators as simple to use as we possibly can. This is without doubt the easiest to use VAT calculator on the market. And it's FREE!

FUNCTIONS:

EZ VAT 2in1 first function is working out the 20% VAT on an amount, showing you both the VAT amount and the result.

EZ VAT second function is to take an amount that already has VAT included, and to break it down into it's two components. Take a look at the screen shots for more details.

Just because this app is simple to use doesn't mean it is basic in quality. You get nice big buttons that vibrate when you touch them, and a large easy to read display.

Check out our range of FREE EZ Toolz Percentage Calculators:

EZ Percent #1, which solves the problem "What is X percent of Y?" For example "What is 20 percent of 150?".

EZ Percent #2, which solves the problem "What is X plus Y percent?" (example: what is 60 plus 20 percent?).

EZ Percent #3, which solves the problem "What is X minus Y percent?" (example: what is 1024 minus 32 percent).

EZ Percent #4, which solves the problem "What is X as a percentage of Y?" (example: what is 50 as a percentage of 200?).

EZ Percent #5, which solves the problem "What number is X a Y percentage of? (example: 12 is 75% of what number?).

EZ Percent #6, which solves the problem "What percent greater than X is Y?" (example: What percent greater than 75 is 100?).

EZ Percent #7, which solves the problem "What percent less than X is Y?" (example: What percent less than 100 is 75?).

EZ Percent #7in1 includes our entire range of EZ Tools percentage calculators, all for less than the price of a small beer.

Check out the screen shots and you'll notice the language the calculator uses: the same language you use. Not a mathematical symbol in sight.

We have worked hard to made these apps completely foolproof. For example if a button is not needed at a particular time it is disabled so you cannot press it by accident.

These apps are so easy to use, we guarantee your stress levels will drop and your productivity will rise just as quickly!

As always, we welcome your feedback. If you have any questions or suggestions, please let us know at info@ringoo.co.uk.

Just because the app is simple to use doesn't mean it is basic in quality. You get nice big buttons that vibrate when you touch them, and a nice clear easy to read display.

We have made this app completely foolproof. For example if a button is not needed at a particular time it is disabled so you cannot press it by accident.

These apps are so easy to use, we guarantee your stress levels will drop and your productivity will rise just as quickly!

As always, we welcome your feedback. If you have any questions or suggestions, please let us know at info@ringoo.co.uk.

EZ Percent 1 solves the problem "What is X percent of Y?" For example "What is 20 percent of 150?". That's the language the calculator uses, the same language you use. Not a mathematical symbol in sight. Have a look at the screenshots and you'll see what we mean.

Check out our other EZ Toolz Percentage apps (coming soon):

EZ Percent 2, which solves the problem "What is X plus Y percent?" (example: what is 100 plus 20 percent?).

EZ Percent 3, which solves the problem "What is X minus Y percent?" (example: what is 1024 minus 32 percent).

EZ Percent 4, which solves the problem "What is X is a percentage of Y?" (example: what is 50 as a percentage of 325.6?).

EZ Percent 5, which solves the problem "What number is X a Y percentage of? (example: 12 is 75% of what number?).

EZ Percent 6, which solves the problem "What percent greater than X is Y?" (example: What percent greater than 75 is 100?).

## Martingale Session Manager

The purpose of the Martingale Session Manager (MSM) is to help you to manage a Martingale, or "doubling up" betting session. It will handle all the maths, all you have to do is enter the odds of the next horse, and tell the program whether you won or lost.

People using the Martingale system very often bet on favourites, so let's say the first horse has odds of 3 to 1 on. You would enter 1 to the left of "to" and 3 to the right of "to".

You would then click on the "Calculate Stake" button". Your stake would appear in the box to the right of the button. You then place your bet.

If you win, simply click on the "Start New Session" and the program resets, and you can start again from the beginning.

If you lose, click on the "No" button, and enter the odds of the next horse.

THE CLEVER BIT....

This time, when you click the "Calculate Stake" button, the program takes into account the money you have lost during the session, and the stake is adjusted so that if your next horse wins, not only do you achieve your target winnings, but you also win your stake(s) back that you have lost during the session.

FEATURES:

Works on QVGA (320 x 240 e.g. HTC Tattoo) screens upward.

Easy to use - everything you need is on one screen.

Built in help screen.

FREE! With ad support.

Please note, use of this program will not increase your chances of winning, it's purpose is to make the betting session simpler by handling all the maths for you.

Enjoy!

## Timesheet Pro For Android

Here we have the much-improved Timesheet Pro, perfect for adding worktimes together in HRS:MINS format. You know how much of a headache that can be, even with a calculator.

WE'VE LISTENED TO YOUR FEEDBACK.

We took note of all your suggestions, and these are the improvements we have made over our original Timesheet app:

You wanted a cleaner, easier to use interface. Check out the screen shots I'm sure you'll agree we nailed that.

You wanted vibrating buttons, for positive click indication. We've done that.

You wanted more error prevention - so we built in safeguards for adding empty cells, mins values larger than 59 etc. We can't get the darn thing to crash, we hope you can't either!

You wanted bigger, easier to read numbers, so we upgraded to a 28 point typeface. Again, have a look at the screenshots.

You didn't want to pay for it. No problem - it's now totally free! It's ad supported (hey guys we have to eat :P), but don't worry, we told the guys at AdMob we only wanted the coolest ads for our users!

As usual, if you have any more suggestions let us know at info@ringoo.co.uk - we always love to hear from you.

Enjoy the app!
