Camera+ would be the perfect replacement for the camera on my phone if it only recorded video as well as take pictures.
Since it can't do video, I keep the Apple camera app on my main page and tuck Camera+ away in a folder. I ONLY use Camera+ to add effects or edit a photo AFTER I've captured it with the default camera app.
The reason I like the default app on my main page and tuck Camera+ away is becaues the default app automatically opens in image capture mode (camera+ requires you open the app then tap the camera button), the default app also has your video recorder right there (camera+ doesn't have video recording), the default app also geotags (if you take a photo with camera+, you lose the geotag when moving it to the camera roll).
Anyone else feel the same way when it comes to your default app vs camera+?
