I would buy that app!
That would be a huge undertaking. I agree that it would be awesome to have.
I want a thermometer app. Tell me the temperature where I and my phone are, not the last reported temp at the local weather station 18 miles away. The temp inside my house, outside in the sun, outside in the shade, etc.
I’ve always wanted a Monopoly app where I could play online against other users.
A very simplified music player with an equalizer would be great. Google Play Music and PowerAmp both have very cluttered interfaces.
I think first you’re going to need a phone that has an ambient temperature sensor in it…
Polaris Office? Bundled on a lot of platforms and available in the App Store. It does a broad emulation of MS Office but I don’t recall trying it with RTF docs.
I’d like an app that gives the camera the infamous Sony nightvision mode. 
Check out Asian Market Shopper
Tested; nope. It will open RTFs perfectly but only by internal conversion to Word and then making it read-only.
I just want a “Find” function to use in my house.
My wife has always wanted a tip calculator to be made that will check your location to let you know what waitstaff actually makes in the area you are eating. She works at a very high end restaurant that is frequented by travelers from other countries which assume that 3 percent is a good tip, because she is making a wage on top of her tip. That is not the case. It costs her 10 percent of the total tab of the table to wait on the table, so she only makes money after the 10 percent.
So she ends up paying to wait on every fourth table she is waiting on.
Do Not Disturb mode puts an icon near the clock.
It doesn’t help if you’ve accidentally flipped the silent switch on the side, but if you’re using it intentionally you might find that works better.
We have a great many CDs in a large custom cabinet, and last night I was looking for a specific CD and wishing I could “Control F” the CD cabinet.
If CDs have information in them that lets iTunes read the titles and songs from them, why can’t I point my iPod or iPad at the CD cabinet, dial up the CD and have it beep or something when I’m getting warmer?
The Galaxy S3 and S4 have one.
I want an app like Unbaby Me that’s actually effective. Unbaby Me is a Chrome app that’s supposed to remove people’s baby pictures from your Facebook news feed and replace them with pictures of dogs, Ke$ha, or what have you. Unfortunately it only removes pictures that have captions with keywords like “baby,” “stroller,” and the like. We need an app that uses pattern recognition to detect and eliminate ALL baby photos.
How would it distinguish between actual babies and, say, dolls? Or paintings of babies? Or children’s-book illustrations? Unless, of course, you want to target using that broad a brush…
(Me, I’d like a version of this that replaces images of pets that people have used as their Facebook profile pics. This ranges between annoying and creepy, depending on what the pet is doing.)
I don’t think this is possible with current technology, but I want to take a picture of something and have the iphone tell me the dimensions.
I want a personal time management app that goes beyond a simple ToDO list, and actually tell me which task I should be doing now. It should allow me to make a task list with estimated time to complete each task, deadline, priority, etc. And combine that information along with the scheduled events in my calendar, and plan out my day for me.
Also, I want a singing training app that can tell me if I’m exactly on the right note, and staying there. I’ve found a Windows software that does this, but it’s a hassle to take a laptop to my singing rehearsals.
Office Suite Pro seems to work. Admittedly it’s a bit expensive for an Android app, but I’ve found it to be very useful. It’s the only app I could find that displayed my PowerPoint slides mostly correctly.
I want an app that lets me view and edit Excel spreadsheets. It has to be local to the iDevice, not like CloudOn that makes changes to the file on a server and suffers performance problems.
I think you could start to do this if you took more than one picture from different angles…
One that would automatically identify and label stars using the camera and time/position of the phone would be kinda nice.
…most of my other ideas are either technically impossible, or morally trouble or just hideous, unfortunately. Ah, well.
