The app was okay for the couple of years I've had it but now it no longer launches and I've gotten absolutely ZERO response from the folks at the Digital Truth even after multiple "service tickets" have been opened. I'm very disappointed and will not be using it again.

Easy install and easy learning curve for the Android version of this app. So nice to see software that was written by someone who knows what is involved in this process! Easily customisable with personalised process settings. The film/chemistry database is extensive and I've already verified that several of the defaults are correct according to the manufacturer's recommendations. Can't find a film or an obscure chemistry? No problems, just edit an existing combination and save it!

The first impression is very good.. But after using it for a while now I miss a few things: - Default setting for the film type (I would like to default to 120) - A way to calculate quantities for mixing fixed and stopbath without having to make a dummy recipe and misuse the developer - An option to copy a recipe to the clipboard or paste it into the app - and a little more involved, but a time for the ilford way of washing the film after development (fill water, agitate 3x, wait a minute, refill water, agitate 6x, wait a minute etc. till 24x) It saves a lot of water but I don't see it possible with the current editor.
