FAQ

1. Why do the colors in the preview sometimes differ from the final image?

No Fusion's default format is HEIF+, achieved through the ProRAW pipeline and No Fusion's proprietary calibration and compression algorithms. The preview is processed through the default pipeline, so in some cases, there may be color differences between the two. If you want colors closer to the viewfinder, you can use the HEIF format, though you will lose the de-sharpening feature.

2. Why does the default camera's telephoto lens focus, but No Fusion doesn't?

As iPhone telephoto lenses continue to extend in range, their minimum focusing distance has also increased. Therefore, when shooting close objects, Apple automatically switches back to the main camera to simulate telephoto cropping without the user's knowledge. You can see which lens was used in the photo's metadata in the gallery.

However, No Fusion is designed not to switch lenses automatically, so if the telephoto lens is too close to the object, it may not be able to focus.

3. Why is there no macro mode?

The native camera's macro mode is achieved by cropping from the ultra-wide-angle lens. If you want to use macro mode, you can switch to the ultra-wide lens and crop with custom focal length settings.

4. Phone overheating and long save times

If HEIF+, MAX, and Live Photo are all enabled simultaneously, save times may be longer because the amount of data that needs to be processed increases, putting a high load on the system. You can adjust the MAX resolution to 24MP.

Meanwhile, we recommend shooting in Negative Film mode. If you need the HEIF+ look, you can batch-select and convert photos in the album during post-processing, saving battery consumption during shooting.

5. Lock Screen Camera Widget

Through the camera control button, or by adding No Fusion to the buttons below the lock screen interface, you can open the lock screen camera widget without unlocking your phone. Unlike opening the app normally, the lock screen camera widget has several limitations.

1. Photos taken cannot be added to the No Fusion album.
2. Cannot read user-imported presets.
3. Under high load, crashes may occur.
4. Please do not exit the widget before saving is complete, otherwise photos will be lost.
5. Tap "Unlock" in the upper right corner of the screen to launch the main app.

If you want to unlock and launch the main app by default every time you start, you can add "Unlock and Launch No Fusion" to the lock screen control widget, and use the Action Button or lock screen lens selection widget to directly unlock and open the app. If you want to automatically unlock and launch the main app when starting via Camera Control, you can enable Settings → Advanced Settings → Force Unlock in No Fusion.

6. Why doesn't the MAX toggle work?

Enabling the MAX toggle allows you to capture photos up to 48MP, but the MAX toggle will not work in the following situations:

• Hardware does not support 48MP lenses.
• Non-ProRAW compatible iPhones when shooting HEIF+ or RAW.
• In manual mode when multi-frame fusion is disabled.

7. Duplicate charges

If you do not cancel your subscription before the end of the trial week, it will be charged automatically after the trial ends. Also, because lifetime premium membership and annual subscription are two separate products and cannot be converted to each other, after purchasing lifetime membership you still need to manually cancel the annual subscription. If you forgot to cancel, please refer to here to request a refund.

8. Family Sharing

Only lifetime purchase supports Family Sharing. Family Sharing may take several hours to take effect after a family member's purchase.
