Not sure

ReLux usually has ongoing sales to remove the 1.99 logo iap but whenever I open the app even on these sale dates, the logo iap is always still in place so I’m not sure what the catch is here. Is it on sale or not on sale? Dev can reach out to remedy if it is the case.

Response from developer

I'm not sure about this, because every time i set the sales dates, they are not precisely active from the midnight of the starting day. Anyway, when you wrote this review there were no more sales. I'll check if it's an alert bug. Thank you. Anyway, you can contact me on the developer email address and I can give you directly the activation link of the offer.

FAQ

What makes reLux's film texture unique?

reLux calculates film texture based on light density, creating organic grain that is finer in highlights and deeper in shadows, mimicking 35mm silver halide behavior. This physical simulation offers a tonal range beyond standard mobile processing.

How does reLux handle video capture?

Cinematic video capture in reLux uses a physics-based approach, recording with 16-bit components. This preserves extensive data, resulting in a cinematic character with soft highlights and deep, readable shadows suitable for professional editing.

The app bypasses zoom to maintain the integrity of ray tracing and depth calculations. This technical choice ensures every pixel is derived directly from the sensor's raw data without digital scaling or multi-lens interference, maximizing fidelity.

What is the output quality of reLux images and videos?

Images and videos are processed at 16 bits per component, retaining an extraordinary amount of information. This provides a professional foundation for further editing, allowing users to refine the look to their preference.
