A storage and bandwidth calculator for video and audio media files. StorageCalculator is a simple way to calculate the storage and bandwidth required to store your footage. The app contains data on a wide array of professional codecs, including ProRes, XAVC, DNxHR and RedCode. The data rate chooser helps you to estimate the data rate required to fit a video of a certain duration into a file of a certain size - for example creating an MP4 which has to fit onto a pen drive. There is also a copy time estimator, which can be used to estimate the time required to copy data between different drives.
Focus Puller

It offers manual focus control with extended focus throw and haptic feedback, as well as LiDAR-based focus control for compatible iOS devices. Both methods allow for remote operation separate from the camera operator.
- Manual focus control with extended throw
- Optional haptic feedback for focus points
- LiDAR focus control for compatible devices
- Remote operation from camera operator
- Focus markers for precision

Control focus on your Blackmagic camera over Bluetooth using LiDAR (for auto-focus) or use a manual control. All of the features can be tested for free for an unlimited time. LiDAR FOCUS CONTROL LiDAR Focus Control is available for iOS devices that have a LiDAR scanner. Simply tap a subject on the iPhone screen, or draw a box around something, and the app will follow it and keep it in focus. REMOTE CONTROL Control LiDAR subject tracking using a second device such as an iPad and see a live video stream and the iOS focus device. Tap to track. MANUAL MODE Manual Mode will work with any iOS device and solves a common problem when using stills lenses to shoot moving pictures: a limited focus throw. Using this app, the focus throw can be extended, allowing precise control to match that of a lens designed for a movie camera. Markers and optional haptic feedback allow the focus puller to feel when the focus reaches a set point without having to look at the image, making the experience closer to a traditional focus puller. Both of these solutions mean the focus puller can stand and operate separate to the camera operator.

Verdict
The clearest difference is rating: StorageCalculator at 4.0 against Focus Puller's 2.9. StorageCalculator also leads on in-app purchases (none vs 1) and iOS requirement (15.6 vs 18.6). Focus Puller's advantage is update cadence (every 2 months vs every 9 months) and review sentiment (50% vs 33%). On price, ads and device support there is nothing between them.

Both are free to download. Focus Puller sells 1 one-off in-app purchase. StorageCalculator asks for nothing beyond the download.
StorageCalculator holds the better App Store score, 4.0 against 2.9. That said, the two scores are not equally well evidenced: Focus Puller has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of StorageCalculator's written reviews are positive against 50% of Focus Puller's, so the app with the better star average is not the one people write more warmly about.
StorageCalculator ships an update every 9 months, Focus Puller every 2 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
