Fall-o-meter

How high are you?


You are standing on a bridge or cliff. It's a long way down. But how high are you? Fallometer answers this question.

Select the thing you will drop, and press START when you drop it, and STOP when it hits the ground.

Fallometer will estimate how far it fell and how fast it was going when it hits the bottom.

Fallometer takes into account air friction, and your position on earth.

Bill Divider

You know the story, you go for dinner with a bunch of people, and they don't want to divide the bill evenly because some owe more than others.

Bill Divider is the bill and tip calculator in the App Store that will help you easily divide the bill between penny pinchers.

Four people go to dinner, three share nachos, everyone has a differently priced main course, two share a drink, and you want to leave a 15% tip. It's no problem to split the check with Bill Divider.

Bill Divider can divide a bill between up to 10 people.

Enter your bill line by line, then divide it across the columns using checkboxes.

Pregnancy Wheel

It simply works like a real pregnancy wheel except that it is more accurate, factors in leap years, and no trees were cut down to make it.

Use your finger to slide the wheel around. It's just like the real thing.

Other pregnancy wheels on the App Store are not actually wheels, and make you key in the dates. This one uses the touch interface to simulate a real pregnancy wheel and lets you set the date easily. Then you can play with the numbers and dates by sliding the wheel back and forth just like you might on a real wheel.

Some pregnancy wheels in the App Store have pages and pages of data that you must navigate. This one keeps things simple and puts all the important data on one screen.

Set the wheel based on LMP, CRL, BPD, or any date or measurement on the screen.
