## What is umop ǝpısdn?

Looking for something unusual, unique, and fun? Type text and flip it upside down. Send email and messages to friends with upside down text.

.ʇxəʇ uʍop əpısdn ɥʇıʍ spuəıɹɟ oʇ SWS puɐ |ıɐɯə puəS .uʍop əpısdn ʇı dı|ɟ puɐ ʇxəʇ ədʎ⊥ ¿ unɟ puɐ ‘ənbıun ‘|ɐnsnun ɓuıɥʇəɯos ɹoɟ ɓuıʞoo⅂

Just enter text and watch it flip. Send as an email, a message, or post to Facebook or Twitter. Shake to clear entry for the next message.

 "uʍop əpısdn" has options that go beyond simple flipping apps:

  1) Choose to convert all to lowercase (tends to produce more readable text).

  2) Handles phone number links so that people can click on links and still make the correct call.

  3) Windows friendly option - some Windows machines are less capable of handling the upside down glyphs, so turn this option on when sending email to Windows friends.

  4) Handles accented characters and emoji.

**Note that upside down messages sent to non-iPhone users do not always work — this is a limitation of their phones, not this software or the iPhone. Mail to Windows/Mac users should always work, as does copy and paste to websites, documents etc. Also note that this only works for languages primarily using the Roman alphabet. Don't try this with Japanese or Russian, for example, as you will be disappointed!**


Here's what beta testers had to say about "uʍop əpısdn":

    "This is the dumbest app I've ever seen — I love it"
        — Elroy, Beta Tester

    "I expect something more useful next time, ok?!"
        — Kaoru, Developer's Wife

Don't waste your time with lesser apps. Get "uʍop əpısdn" and start messaging your friends now! Even the app name is upside down — that's attention to detail! Though a problem for people searching for the app — didn't think that one through when I came up with the name...

## Key features

- Flip text upside down
- Convert to lowercase
- Handle phone number links
- Windows compatibility option
- Support accented characters and emoji

*2011-02-05, version 1.1*

App sans grand intérêt à la longue mais bon ça marche, ça met le texte à l'envers comme promis donc RAS!

### 1/5 — I've had more productive craps.

*2011-02-04*

Glad I was taking a dump during downloading and trying this app so I can't say my time was wasted. SMS and e-mail don't work. Don't waste your time.

### 5/5 — I got 3 words for all of u's.

COOLEST APP EVER!!!!!!!

### 4/5 — Original

*2011-02-03, version 1.1*

Bien marrant au début

### 5/5 — Best upside down app available!

*2010-09-02*

I'm not sure what this sabre02au person is talking about, but it clearly states in the app description that messages sent to non-iPhones may not work properly. This app works great with all my mates who have iPhones. No app can work around the limitations of inferior phones. Highly recommended!!!

### 1/5 — Give it a miss!!!

*2010-08-27*

I like the app....but everyone I sent a message to, can't read it because it comes out as strange characters - waste of money
