One thing I’ve been tracking is that while these two apps are essentially the same app, it’s MUCH more popular on Android than on the iPhone.

Android Market vs. iPhone App Store
Here’s a quick screenshot of the current Android Market stats:


Prayers to Share is getting between 250-500 downloads per day in the Android Market. But the same iPhone app gets 25-50 downloads per day through the App Store.

The 10x difference is no doubt due to ease of discoverability on the Android Market vs. the App Store. It’s a Top 20 Most Popular App in the Social Category of the Android Market and is easy for new users to find while it’s buried in the iPhone App store listings.

Red States vs. Blue States
But I had a funny conversation the other day about Verizon Red States and AT&T Blue States. It was probably a result of being hammered over the head by too many Verizon commercials, but more likely due to too much caffeine.

Here’s the gist of it:

“Those Verizon commercials with the Red and Blue maps remind me of Republican Red states and Democratic blue states.”

“If you actually look at the AT&T blue map in the commercial, it’s pretty sad. It looks like it’s just the coasts and major metropolitan areas.

There’s some truth to those commercials. People I know in NYC and the West Coast love their iPhones, but my friends in the midwest won’t even consider an iPhone because AT&T coverage is so poor near them. Not just 3G coverage, they have a bad perception of any AT&T coverage in their area.

Maybe that’s why Prayers to Share does better in devout Verizon Red States than wicked AT&T Blue States.

Well, there have been several prayers for God to end abortion from Android phones and one person even prayed for Obama to be shot.

Hmm, maybe I should just focus on pious Android apps for Red States since the amoral iPhone app market is pretty crowded.”

OK, maybe I should cut back on the caffeine.

It’s a little tricky finding the most popular “things to do before you die” because people phrase things differently, but here’s the Top 20 Most Popular Bucket List Items shared so far on both apps.

Aargh, I got my first iPhone app rejection!

My first 6 submissions and updates all went smoothly, but this time I got dinged by the dreaded “device data collection”/”personal user data” notice for uploading info to my webserver.

Your application cannot be posted to the App Store because it violates section 3.3.6 of the iPhone Developer Program License Agreement:

“Any form of user or device data collection, or image, picture or voice capture or recording performed by the Application (collectively “Recordings”), and any form of user data, content or information processing, maintenance, uploading, syncing, or transmission performed by the Application (collectively “Transmissions”) must comply with all applicable privacy laws and regulations as well as any Apple program requirements related to such aspects, including but not limited to any notice or consent requirements. In particular, a reasonably conspicuous audio, visual, or other indicator must be displayed to the user as part of the Application to indicate that a Recording is taking place.”

Please refer to the attached images.

Please make it clear to the user that their personal user data is being uploaded to your server, and obtain their consent before submission.

I think I screwed up with my fix, though.  In the new version, I now throw up an alert each time someone shares info with my server which is sure to annoy users.

After googling a bit for this type of rejection, it looks like they’ve changed the verbage of this rejection, and they used to suggest a solution with this type of rejection:

Your application cannot be posted to the App Store because it violates section 3.3.6 of the iPhone SDK Agreement:

“Any form of user or device data collection, or image, picture or voice capture or recording performed by the Application (collectively “Recordings”), and any form of user data, content or information uploading, syncing, or transmission performed by the Application (collectively “Transmissions”) must comply with all applicable privacy laws and regulations as well as any Apple program requirements related to such aspects, including but not limited to any notice or consent requirements. In particular, a reasonably conspicuous visual indicator must be displayed to the user as part of the Application to indicate that a Recording is taking place.”

Please make it clear to the user that their personal user data is being uploaded to your server by way of an alert upon first launch or a text label before the score submission.

I’m tempted to reject the current binary and make the warning less obtrusive, but I don’t want to reset my place in the approval queue.

But Instruments proved too frustrating, so I downloaded Clang from here. It was a little tricky to install, but after a few hurdles, I found 20 memory leaks in my app. If you’re developing iPhone apps, you really need to check out Clang if you haven’t already.

Two things tripped me up in the installation process.

1. Could not find clang-cc line

The solution for this was at cramfighter.com. Basically I need to change some projects settings.

2. syntax error before ‘AT_NAME’ token

This was tricker to figure out because there errors weren’t in my files and looks like the problem started with the 3.0 SDK. I ended up going with this solution as a temporary workaround. This involved commenting out the UILocalizedIndexedCollation.h import in UIKit.h.

As is often the case, after I got things up and running, I found a great page with an intro to Clang at fruitstandsoftware.com.

I’d tried a few times to get a nice Progress Bar showing how many bytes have been uploaded, but gave up because I could never get it to work. Then today I noticed the didSendBodyData delegate method for NSURLConnection. I don’t know how I missed this before, but I feel like an idiot.

NSURLConnection Class Reference

connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite:
Sent as the body (message data) of a request is transmitted (such as in an http POST request).

- (void)connection:(NSURLConnection *)connection didSendBodyData:(NSInteger)bytesWritten totalBytesWritten:(NSINteger)totalBytesWritten totalBytesExpectedToWrite:(NSInteger)totalBytesExpectedToWrite
Parameters

connection
The connection sending the message.
bytesWritten
The number of bytes written in the latest write.
totalBytesWritten
The total number of bytes written for this connection.
totalBytesExpectedToWrite
The number of bytes the connection expects to write.

Discussion

This method provides an estimate of the progress of a URL upload.

The value of totalBytesExpectedToWrite may change during the upload if the request needs to be retransmitted due to a lost connection or an authentication challenge from the server.

I’ve run into several web developers who want to make cool webapps for the iPhone using its location information.  Unfortunately, even though they’re killer web devs, there are several hurdles to overcome such as not having a Mac, needing to learn Objective C, obtaining a certificate, etc.

So I proposed we just create a generic, skeleton, native iPhone app that would access our websites using UIWebView and do all the heavy lifting on the web side.  A generic browser with a URL bar at the top but providing CoreLocation information to the website.  Essentially, like Safari but allowing the website access to location information.

This solved several of the issues we’d been thinking of:

• We don’t all have to pay the SDK fee and spend weeks/months learning it.  Web developers can focus on web development.
• Each of us doesn’t have to go through the hassle of creating an app, getting it approved, and maintaining it over time.  We can just share the generic browser/client.
• The App Store is just going to get more crowded, I’m already getting tired of installing apps and uninstalling them right away.  A general location browser allows someone to quickly try out a site without having to find and download an app.

I’d like to see this project open-sourced, although there’s been a lot of confusion recently if that’s allowed with the current SDK agreement.

There are some folks working on similar concepts like PhoneGap and WebToNative, but I think there’s room for a completely simple solution like this.

Ideally, location information would be an option to expose within Safari, but I’m not convinced that will ever happen.  There are serious privacy issues if something like that were built into Safari, and it’s definitely not for most people. But there’s a subset of folks out there that have a use for something like Metosphere.  Kind of like the location info provided in Google Gears or  the Skyhook Firefox extension.

I was hoping to provide Lat/Long information to websites through HTTP headers, but that’s not available in UIWebView, so webpages that want location information from the Metosphere browser will need to include a simple Javascript function.

Here’s a summary of how this works:

1. Install Metosphere on your iPhone (hope it gets approved!)
2. Create a webpage with a Javascript function called updateLocation that looks something like this:
   <html><head>
   <script language=”javascript”>
   var latitude=0;    //these will be set when the Metosphere browser calls updateLocation()
   var longitude=0;function updateLocation(metoLat, metoLng){
   latitude=metoLat;
   longitude=metoLng;
   document.getElementById(“message”).innerHTML = “Your latitude=”+latitude + ” and longitude=” + longitude;
   //now do something cool with latitude and longitude set
   }
   </script></head>
   <body>
   <div id=”message”>Location not available</div>
   </body>
   </html>
3. Enter your webpage’s URL in Metosphere’s location bar and your page should have access to the latitude and longitude.
   
4. Create a webpage/webapp that does something cool with this location information.

Anyway, that’s the current direction for this project.  Some cool features to add down the road would be:

• integration with Yahoo’s FireEagle
• a setting to allow the browser to periodically update location info at set intervals
• the ability to create extensions like Firefox

I decided to focus on an iPhone webapp for now, since most people I know have unJailbroken iPhones. Thankfully, FireEagle handles the location info nicely. The backend is the same, so any geospatial information created in either the iPhone or Android version shows up in the same, um, metosphere.

Features:
- Create geotagged objects at your location (messages, alerts, events, reviews, etc.)
- View geotagged objects created by others in your proximity (list or map)
- List nearby events from Upcoming and Eventful
- List nearby geotagged Wikipedia pages
- I left out the GeoBlog functionality for now since that’s still in flux while I’m finalizing the forthcoming Android release.
- I used the CiUI iPhone UI instead of IUI because it seems faster.
