Handy handy!


It's SO handy to always have a ruler with you no matter where you go! When I upgraded my iPhone, one of the first few apps that I downloaded was my handy ruler! Seriously! For even very long things--- if you take pages of paper and tape them all together, you can mark out a measuring surface as long as you need! I've used this technique for measuring out everything from a few millimeters to inches, while designing gemstone jewelry, all the way up to 34 inches on a Victoria's Secret website purchase! (You can kinda tell I'm a girly girl, can't you? HaHa! My point was there are most definitely many uses, no matter what you're doing!) -- This ruler app is fantastic for all lengths and all jobs where you need to measure something. I fact, I used this tiny iPhone to make an eight FOOT long "measuring tape" to determine the length of a sectional couch that I wanted to buy online! As I said, handy handy! Especially when you think outside the box and create measuring tapes for all box sizes! Who'd have ever thunk I'd ever be excitedly writing a review for an iPhone sized ruler!?? :) Enjoy!

A ruler should just act as a ruler.


I understand the need for ads. I develop apps myself. But a ruler shouldn't be asking for permission to send push notifications. Still, whatever. I disabled those; there's a bigger problem.

The app gave me a pop-up notification asking if I want to download a "free app." What app? Who knows? I won't tolerate mysterious ad pop-ups from any app. Just use banner ads or interstitials like a normal app.

Not to mention this app also comes with longer rulers in the form of paid DLC. What, to get a meter-long ruler on a five-inch phone? Thanks, I'll pass.

Great for what it is. Not perfect.

I think it's great that someone put a ruler on the iPhone. I downloaded it so I could measure myself down under. The results don't seem right to me, but at least it gives me an estimate that I can throw at prospects. I just ended up finding out how tall my phone is and then putting it side by side with Johnson. Gave me better results. Turns out my phone is smaller.
