I have a new app on the app store! It’s called SensaView, you can get it here. SensaView shows you the output from the various sensors on your iOS device. It will report location (lat, long, altitude), vector (course, speed, heading), accuracy estimates, accelerometer, gyroscope, and magnetometer. It’s not super exciting but it’s laying the … Continue reading New app: SensaView
There seems to be no standard way of dealing with UIPickerViews. Sometimes they are attached right to the bottom of the interface and never move around (like in the built-in Clock application.) Other times they fly up from the bottom like the keyboard but are embedded in a UIToolbar or UIActionSheet. I’ve come up with … Continue reading Showing and Dismissing a UIPickerView Control
What do we have this week? My MD5 Calculator has been updated to include a way to tip the developer $0.99 (or whatever the regional equivalent is) via in-app purchase. Fun! Also, I removed the ads. Yuck is gone! Oh, and it’s pretty cool when I have to remember what apps are still awaiting approval.
This is just going to be a little post on sales. I hate talking about money and marketing. But it’s sometimes necessary. So here we go. Item #1: iAds. I added ads to three of my free apps. They are not high traffic apps and don’t have a huge level of engagement. I’ve made maybe … Continue reading A small note on sales.
PizzaPal has been updated to 1.1 with the following changes: Removed iAds. Added 4th pizza comparator. Yeah, I know, that’s kind of cheap to count that as an app release. Whatever, making an app a week is no picnic. Oh, also, if you do any kind of coding/programming, you should totally check this out: I’ve … Continue reading App-A-Week Challenge Update, also Font Tip! (Also, Snippets!)
You thought I forgot about you. I didn’t. I have apps waiting on approval. I have new apps that are *this* close to being done. I have other app activity. App app app. So, yeah. App.
Hey folks. I know you’re all just on the edge of your seats waiting to find out what’s in store for this week. Here’s what’s going on: The music/pitch app I was working on will need more work. I thought I had a good implementation of the “zero-crossing” pitch detection algorithm but, while it works … Continue reading App-A-Week Challenge, Week 5
Another week, another app! Here’s the one I’ve been working on for a few weeks now. I finally got it all nailed down and it got approved by Apple! It’s called BrewTime and you can get it right here! Let’s take a look-see: What did we learn about for this app? UITableViews, NSTimers, UILocalNotifications, etc.
…today I made a little thing that detects pitch using the zero-crossing method. I still have to nail down a few things but I’ll post the code when I’m done. Also, I should test it with actual instruments. Also, dealing with Audio Units is a major pain in the ass. That is all. Love, Jeff.
Hey kids, just a small update today. Here’s what I’ve been playing with: It’s an iPhone app for devices running iOS 5+ that takes video frames from the front camera and performs a vImageBoxConvolve twice to simulate a gaussian blur. It does this in realtime (well, ~15fps) and the slider sets the blur radius. The … Continue reading AVCaptureSession + vImageBoxConvolve_ARGB8888 = FUN;
