Monochrome

This is the only app I could find that has an RGB channel mixer to influence the tonality of the mono output. I do wish it had more control over contrast and brightness (sliders instead of stops), and that it would allow to add some tint to the final mono image. But in general, this is a nice, simple, app that delivers exactly what it says it will. I highly recommend it.

Small and simple app. . Download, when you like black & white pictures. If you want to edit your picture more then b&w then this app is not for you. . 5 stars because it is a small and effective app

A simple and powerful Black &White app that does a great job.

So very useful. A keeper. Thanks.

Does what it says. Great!

Samsung Galaxy S5 and Network connected HP LaserJet 5p Printer. Using this APP has helped color photos to be printed very nice, useful and not washed out. I set RGB to 100% and 'Tone' to Hard and 'Curve' to -2 then save. Using the Hammermill APP provides a nice print. Thank you for this app.
