The few it does, it does it well. Shortly: takes many shots to average them and increase the signal to noise ratio. Yet to be improved/added: - better stability (on iPhone 4s, full res, it shuts down very often while saving the processed picture - possibility to make aperture/ISO bracketing (for example: taking 8 pictures from - 2IL to +2IL) I would rate the App 5 stars for that 2 first points. Then: - a step further: picture auto-alignment to avoid tripod - final dream: oversampling and super-resolution. Wow! Good luck to the dev team :-)
