Lock ISO, shutter speed, white balance and focus, let the calculator set the interval, and the app assembles your full-quality photos into a video. [Download on the App Store](https://apps.apple.com/app/interval-pro-time-lapse-4k/id6799860142) iPhone, iOS 17 or later. - Free to download - One-time purchase of €7.99, no subscription - No data collected ## Why your iPhone timelapse flickers, and how the app prevents it In the iPhone's Camera app, a timelapse starts with a single button: no manual control over ISO, shutter speed or white balance. When exposure readjusts automatically between two photos, the video flickers. Interval lets you set ISO, shutter speed, white balance and focus, then lock them on the current reading. Every photo is exposed the same, from first to last. - 4:3, 16:9, 3:2 or 1:1 framing, shown on the viewfinder before you shoot - Rule-of-thirds grid recalculated for the chosen format - Horizon level computed from gravity *Lockable manual controls: ISO, shutter speed, white balance and focus* ## Interval Pro or the iPhone's built-in timelapse? The built-in mode is fine for a quick timelapse. Interval is for when you want to control the result. ### iPhone Camera app - Nothing to install, free - One button - No manual control of ISO, shutter speed or white balance - No interval to choose ### Interval Pro - Lockable ISO, shutter speed, white balance and focus - Free interval, from 0.5 s to several minutes, calculated for you - Full-quality HEIC photos kept, re-export in 1080p or 4K - Hyperlapse mode with anchor point and ghost image [Download on the App Store](https://apps.apple.com/app/interval-pro-time-lapse-4k/id6799860142) ## How many photos, which interval? The calculator answers before you start Enter how long the scene lasts and how long you want the video: the app computes the interval. Or enter the interval, and it tells you the final video length. Before you start, you see the photo count, the disk space and the battery needed. Example: 900 photos, 3.15 GB, 1 h of shooting for 30 s of video. If the app knows a session cannot finish, it refuses to start it. [Open the interval calculator](https://interval-pro.com/en/timelapse-calculator/) *Interval calculator: 4.0 s between photos, 900 photos, 3.15 GB* ## Timelapse or hyperlapse: two modes in one app ### Timelapse Your iPhone sits still, on a surface or a tripod. The app fires on its own at a steady interval. Good for a sunset, a building site, clouds, a crowd. ### Hyperlapse You move between photos. The app shows an anchor point to aim at and a ghost image of the previous photo, then stabilizes the sequence at export. ## Stabilized hyperlapse: the anchor point and the ghost image Before the first photo, tap the anchor point you want to keep at the same spot in the frame. As you move, the previous photo stays visible on the viewfinder as a ghost image. At assembly, the app analyzes photos two by two, smooths the path and crops each frame by 8 to 20 % depending on how much you actually moved. *Hyperlapse mode: anchor point set on a street lit at dusk* ## Built for long sessions: heat, calls, battery While shooting, the app steps aside: everything fades to black, and only the counter and the progress ring remain. The screen dims to save battery. If the iPhone gets too hot, the app pauses, then resumes. An incoming call breaks nothing: the session picks up where it stopped, locked settings included. *Session in progress: counter and progress ring on a black screen* ## Full-quality HEIC photos, 1080p or 4K export: nothing is thrown away Every session becomes a project: full-quality HEIC photos, a thumbnail and the exports you already made. Nothing is deleted after export, so you can re-export later at another resolution without reshooting. - 1080p or 4K export, at 24, 25, 30 or 60 frames per second - Saved straight to Photos - Streamed assembly: thousands of photos without filling memory *Project list: 6 projects, 3,130 photos, 1 min 45 s of video* *Project detail: 420 source photos, 14 s of video, 3.0 s interval* *Export screen: 1080p or 4K resolution, frames per second, aspect ratio* ## Free to start, 4K with one purchase No subscription.

Export is limited to 1080p with a watermark, and three full-quality exports are included so you can judge the result. ### Do 4K and the removal of the watermark require a subscription? No. The one-time Interval Pro purchase (€7.99 in France) unlocks 4K, removes the watermark and lifts the export limit, for good. ### What is the difference with the iPhone Camera app's timelapse? The built-in mode starts with a single button. Interval adds lockable manual controls, a free interval with a calculator, stabilized hyperlapse and full-quality photos you can re-export. ### Which interval should I choose? It depends on the scene and on how long you want the video. The calculator works it out for you. [Try the calculator, with starting points by type of scene.](https://interval-pro.com/en/timelapse-calculator/) ### How much storage does a timelapse take? For 900 full-quality photos, expect about 3.15 GB. The app shows the space needed before you start, and refuses to begin a session it knows it cannot finish. ### Are my photos sent anywhere? No. Interval runs entirely on your iPhone, with no account and no server. Exported videos are added to your photo library only if you allow it. ### Can I re-export a project later? Yes. The HEIC photos stay in the project, so you can re-export at another resolution or frame rate at any time. 4K export requires Interval Pro. ### Do I need to keep the screen on while shooting? Yes, keep the app open. The screen dims automatically to save battery. ### Which devices are supported? Interval Pro is built for iPhone, running iOS 17 or later, and exists only on iPhone. The interface is available in English, French, Spanish and German. ## Shoot your first timelapse Download Interval Pro, set your iPhone down, and let the calculator pick the interval.
