People who rated this low for interruptions, light changes, flashes from objects in front of the camera and white balance flickers, please read, Id love to help. Theres a few things that you absolutely have to do when starting a timelapse.
1: NOTIFICATION INTERRUPTION FIX. Turn your phone in airplane mode. This will take away 90% of what interrupts your timelapse. By putting it in airplane mode (for those of you that dont know) it cuts off all wireless signals from entering or exiting the phone, making push notifications (or in our case being timelapsers..."interruptions") from internet sources impossible. But some will still get through, which brings us here:
2: NOTIFICATION INTERRUPTION FIX 2. Go into settings, and turn on "Do Not Disturb". You may not even have to put it in airplane mode if you do this, but I always do just to be safe.
3: BATTERY NOTIFICATION FIX.
Yeah you guessed it, just simply plug your phone in. Since in iOS 6 it is currently impossible to disable low battery notifications, they WILL interrupt and stop your timelapse. So plug your phone into power.
4: EXPOSURE AND WHITE BALANCE.
In the corner there is a page curl that you can tap for some semi-advanced options. Tap this and turn off smart exposure, (this will guess at the exposure changes and compensate on its own and it does okay, but sometimes results in light flickers) turn on lock exposure on start, focus and white balance. A perfect timelapse revolves around settings not changing, so locking them all is always a good idea.
5: OBJECT FLICKERS/CONTROLLING MOTION BLUR.
Have you taken a video of the sunset and had birds or bugs fly in front of your camera and had the end result be little black flashes for just 1 or 2 frames of the bugs/birds? Really simple fix. Turn your shutter speed down...which means go to a higher number. Taking the shutter speed to say...1-3 seconds, will make anything that passes in front of the camera for just a split second, so blurry it wont even show up in the finished product. Dont ever set it to auto. So if youre driving in a car doing a timelapse, put your shutter speed at 3 -5 seconds and youll get some nice motion blur. And if youre doing something with people in it, you may want them to be clearer so raise it to 1/4.
6: SETTING EXPOSURE/FOCUS.
This is a very important step. When youre in the framing window (where you see the live view of what youre about to shoot) hold down with 2 fingers to split apart the focus and the exposure. Move the exposure on something thats as bright or dark as you want your whole shot to be. But keep in mind, if youre doing a sunset, purposely over expose your shot at first, because trust me, itll be black halfway through towards the end if you dont. And then move your focus obviously on what you want to focus on.
7: SOME VERY USEFUL TIPS.
TRIPOD: A great idea I figured out for a tripod is a shoe. Wedge the phone inside the opening of a shoe and move it around to frame your shot. Make sure the camera is on the top though.
FIRST FRAME PERFECTION: ever taken one and had your first frame be different from you hitting "start"? Theres a setting in the middle window that allows you to start it 1-59 seconds after tap. Which means you hit start, and it wont start until the set time you entered has elapsed. This really helps make the beginning of your timelapse flawless.
ADD SOME MUSIC: why not? It gives you the option to add a little music to your timelapse. Spice it up a bit.
And from my experience of using this app, thats about all the tips I got for you guys! If you follow all these steps its more then worth the money. Thanks for reading and happy timelapsing!
