SWRLY is a modern take on the original swirly lens, the Petzval, created in 1840 by Josef Petzval. This lens design was one of the first portrait lenses and is characterized by a unique swirly bokeh effect. Many of the earliest photos (daguerreotypes, tintypes, etc.) were captured with Petzval lenses.

The Petzval lens has a sharp center region surrounded by swirly bokeh, making it fantastic for portraits. SWRLY is the first app to faithfully recreate this effect.

- Unique swirly bokeh authentic to the original lens
- Great for portraits
- Simple to use with great results
- Presets like antique film types such as daguerreotype, tintype, etc.

Does a beautiful job


Update: the app will save at about 10mp if yo use the Save icon in the upper right corner, and select save. If you chose More and use the save image icon in Share menu, you get the 2.8 mp save. Not sure why. Love this app, it mimics the Helios 44-2 and the Petzval style of swirling bokeh. Very realistic.

Original Review: I really like the effect created by the app. It does a terrific job of mimicking my old Russian lenses that produce that same swirling bokeh. With plenty of on-board editing controls, it makes for a pleasant editing experience. The only serious (fatal) flaw for me is the terrible output resolution. I get only about 2.8mp after starting with a 20mp image. This is just unacceptable with today's hi-res images, even iDevice cameras are capturing images in the 8-12mp range. This needs to be fixed for this app to compete.

Exactly what I was looking for!


This app is EXACTLY what I was looking for. I wanted that swirly bokeh effect and I finally got it! I was searching for it for a long time. Thank you for creating this.

I will be recommending this app to my friends!!



Sometimes there is an app that really hits the mark of simulation!! This one does that!! Great job developer!! Makes me want to pull out the old 8x10 and my Ross of London lens from 1800’s and shoot with it again:)
