Easy Timelapse · iPhone and iPad app

Smooth timelapses, from day to night.

Point your iPhone at the sky and tap record. As the light changes, the exposure changes slowly, frame by frame, so day to night looks smooth. Pro dials are one tap away when you want them.

How it works

Easy by default. Pro when you want it.

  1. Frame the shot

    Pick a lens and a preset like Sunset. Put the phone on a tripod.

  2. Tap record

    The exposure follows the light slowly, so the video stays smooth.

  3. Export the video

    Pick a shape and a size. Share it or save it to Photos.

What it does

  • Shoot day to night, smoothly

    Exposure changes a little each frame, so sunsets and sunrises don't flicker.

  • Turn real dials

    Mode, ISO, shutter, EV, white balance, focus and zoom.

  • Pick a lens

    Apple's lens marks, like 0.5×, 1×, 2×, 4×, 8× on iPhone 17 Pro. Zoom in between.

  • Shoot RAW

    12 MP RAW by default, for the most room to edit.

  • See the light live

    Histogram from the RAW frame, zebras or false colour, waveform, focus peaking, level and grid.

  • Catch clipping early

    Alerts at limits you set. Highlight guard takes a little light off when a frame clips.

  • Bracket for HDR

    3 or 5 shots for every frame, merged when you export.

  • Stop lamp flicker

    Anti-flicker for 50 Hz and 60 Hz lights.

  • Know your numbers

    An interval calculator, and how much storage time is left.

  • Plan the light

    Sunrise, sunset, golden and blue hour, the moon and the Milky Way. One tap to shoot that time.

  • Export any shape

    16:9, 9:16, 1:1, 4:5 at 1080p, 4K or 8K, in HEVC. With deflicker and crop zoom.

  • Bring camera photos

    Import RAW photos from your camera (CR3, NEF, ARW) and turn them into a timelapse.

Leave the phone. Watch the shoot.

Set it up once. Then check the frames and the exposure without touching the iPhone.

  • Apple Watch

    Start, stop and AE lock from your wrist.

  • Lock Screen

    A Live Activity shows the shoot on the Lock Screen and in the Dynamic Island.

Your shots stay on your device.

Questions

Which iPhone or iPad do I need?

Any iPhone or iPad with iOS 18 or iPadOS 18 or later. The Apple Watch app needs watchOS 11 or later. The lenses and photo sizes you see depend on your device.

Why does the video not flicker?

At sunset the light changes fast. If the camera jumps to each new exposure, the video flickers. Easy Timelapse eases each change in over several frames, so the brightness moves smoothly.

Does it need my location?

No. If you allow it, the app works out where the sun is, on your device, for the planner and for how dark night should look. Without it, the app still works and night is kept as bright as day.

Can I export in 8K?

With Lifetime, yes, when the photos are big enough: 48 MP ProRAW from the iPhone, or RAW photos from your camera. 12 MP photos go up to 4K.

What happens after the free days?

You can still start 1 new shoot a day and export up to 1080p, free. Auto exposure, EV and AE lock stay free. Easy Timelapse Lifetime unlocks the rest for good.
