Questions
(04)How is Flattr different from other double exposure apps?
Flattr merges photos without blending modes, so multiple exposures keep natural tones instead of the artificial, over-processed look blending modes tend to give.
Can I see the result before saving?
Yes. Flattr shows a real-time preview that updates as you adjust the merge.
Do my photos leave my device?
No. All merging happens on your device, with no cloud processing, and the original photo quality is kept. See our Privacy Policy for details.
Is Flattr free?
Yes, completely. Flattr has no in-app purchases, no subscription and no ads.
