Shoot Simply! We championship "nature and zero", resist “overprocessing and complex edits”. One tap delivers high quality film-like photos with classic tones and organic detail. Fio elevates iPhone photography by countering overprocessed computational imaging, helping you reclaim the authentic joy of shooting. Fio provides two photography modes: • 「ZERO」 algorithm-free film photography mode | 2「PRD」 computational photography mode.
