What is a good idea for a new iPhone app?

I have been thinking a lot lately and really want to do something that would make people's lives a lot easier. I have been trying to brainstorm ideas on an app that I would like to create. Does anyone have a good idea for an app that they would like to see? If so, how much would you pay for it?

IPhone 5c App Store and time problem?

I have to problems:
When I want to download apps on my iPhone 5c it doesn't really download I type in my password and it loads but does not download and goes back to saying "get" in the box.

My time is totally off like totally. I have tried to set it manually and do it automatically but it doesn't work. It just goes back to the old time that is totally wrong. It is iOS updated but it still messes up. If there's an app that changes the lock screen time or something that would work too.

I just recently purchased an iPhone 4s and I want to know what's wrong with it?

I bought an iPhone 4s of Craigslist and everything seems to be working fine. The guy before the purchase told me that the phone was unlocked. However, when I went to my carrier (Bell) they cut my sim into a micro-sim but the phone read it as No Sim. The sim already in the phone when I purchased it read No Service. The micro-sim that was already in it was from Fido. Then I tried to put a micro-sim that belonged to Rogers but didn't work now because our contract with Rogers was over. The phone read the Roger's sim as No Service as well. So what's the problem? Is the phone locked? Or could it be my normal sim that was cut into a micro-sim (Bell)? Any help would be awesome.

I got an Iphone from eBay and need to reset it without any passwords?

I got an Iphone from eBay and it is still linked to a icloud account and when I contacted the seller he did not reply so I waited 2 months and no reply came. I still want to keep the Iphone but I need a way to reset it without knowing the password for Icloud and any of the details. I also tried to put the Iphone into recovery mode but failed. I held the power and home button for 10 seconds and released the power button after 10 seconds but kept holding the home button. So now it has a black screen and it is being un-responsive. When I attached it to my computer and launched Itunes it recognized the the iphone was in recovery mode. I basically want to try and reset it to factory settings.

Would You Trade an iPhone 5 64GB for an HTC One M8?

I have an iPhone 5… Someone offered to trade it for an HTC One M8

I think the iphone features are top of the line for its time, which is the year 2012 and is just as fine today in 2015. Apple gives updates to even old phones, though i'm scared it might be near its last iOS update for iphone 5… Also I hate iTunes. Having to go through it everytime i wanna touch music or videos is a pain.

The HTC M8 is a phone from year 2014. Has a bigger screen. Runs on on Android, so no iTunes needed. The specs are comparable to iphone 6 "almost"… Downside, the camera. Only 4mp. Though its ultrapixels, whatever that means. Pictures look decent from what iv see on youtube, but not the best.

I would easily take the M8… But the camera makes me nervous. Thats the most important part. Other than that the M8 wins.

your opinions?
