ReLens for Android

Quick summary

ReLens is a free mobile photography app from Accordion that uses computational photography and AI to help your phone produce images that resemble those from a digital SLR. It lets you add depth-of-field effects, emulate classic lens characteristics, and tweak background blur with an adjustable aperture control — all from your device.

Main features

• Depth brush for selective focus and more precise depth editing.
• Adjustable aperture simulation to control how much background blur appears.
• Emulation of vintage SLR optics so you can recreate distinctive lens flares and bokeh shapes.
• A straightforward interface that integrates AI-driven depth recalculation to produce realistic-looking results.

Recommended alternative

Focos (free) — a popular substitute focused on advanced bokeh control and realistic blur effects for smartphone photos.

Things to keep in mind

• There is a learning curve for the more advanced editing tools; expect to spend a little time mastering them.
• Over-applying simulated effects can introduce compression artifacts or subtle image degradation.
• You may encounter occasional glitches or background noise in processed images.
• The simulated results won’t always match the physics and fidelity of a true DSLR lens.

Practical verdict

ReLens is a useful, no-cost option if you want to experiment with DSLR-style depth and lens effects on your phone. It offers powerful, creative tools but won’t perfectly replace real optical hardware. Try it for casual and creative edits, but be mindful of processing limits and the time needed to learn its more advanced controls.
