Hello, author of Lumariver Profile Designer here. As far as I know if you install it on one device you should have access to it on another device for free, as long as logged in to the store with the same user, that is you should be able to have it on the tablet and phone at the same time, I know I have that myself :-). It's a while ago I worked with app stores though so I'm no better than anyone else in supporting on installation issues (it's separate from actually programming the app).
About the manual I haven't made any help inside the app, it would be nice to have but it didn't make it in there. As a workaround what you could do is to print the online manual to a PDF and then store it on the device. But I think you will find after you have set it up to your liking and used it a few times that you don't need the manual.
I think of this type of app as much of a learning tool. Ansel Adams et al were masters at technique, his most famous shot he did even without a light meter, but few of us photograph shoot in that volume to be that confident. Then having something to look at can be helpful, and during periods I shoot more often I find I don't need to look at the app as often. Before I used an app I used printed tables, well I still do as a complement as my phone may not have batteries all the time.
Heh, if you where a true luddite you wouldn't use a light meter either . A depth of field app is just an alternative/complement to printed depth of field tables, it won't get in the way of pre-visualization. What I find useful in addition to a depth of field app though is a viewfinder app to test compositions before mounting the camera, which is an alternative to a classic hardware viewfinder, which is an alternative to framing with your hands, which is an alternative to just see and get the composition without any aids whatsoever, and it does feel a bit like cheating , but I just don't shoot often enough to have the confidence and skill to make apps not useful. I do make sure that I can do without them as batteries etc, but I work slower without them.
Solved both my issues. PlayStore allowed me to download and install Lumariver about 24 hours later. And Chrome has a download feature I hadn't seen before that got the e-manual for me (normally a Firefox user).
Drew, your point is well made and I usually wouldn't bother with such. I do use the smartphone for pinhole and reciprocity calculations, as well as a marvellous Android tool called The Photographer's Ephemeris which uses the GPS location to predict the direction of the sun and moon at any time during the day with respect to a current or future location.
Cheers, Peter.
No one, of course, has to use any of this. If someone finds these things useful, why should others be bothered?
“You often feel tired, not because you've done too much, but because you've done too little of what sparks a light in you.”

Peter:
The ephemeris does sound good. One of the trickiest outdoors images to get is the rising or setting sun in alignment with some significant object. I have done this in the past, but had to with observatiolns using a compass . . . .means you have to have two days of clear weather and get up well before the crack of dawn.
This app would allow a photographer to scout a location during the day of the intended sunset photo and be within feet of the exact position as the sun goes down. Sunrise shots could be scouted at any time the day before. Yeah, I can see myself doing that.
A great idea. Luddite converted.

Really? What’s an App? I use my brain and forty years of experience.
I am a troglodyte. It would take away some of the "fun" for me to use a bunch of apps when creating images.
I guess I can see someone using a smart phone for calculations and technical reference. However the viewfinder app . . .
Look into the ground glass. The ground glass is truth.

Yep. I think "Holders" is gone. When I switched phones it took all my data with it. I have not found anything that gives the same functionality out of the box but I am experimenting with the app GeneralDB. This is basically an SQL database on an iPhone that lets you define your own tables (e.g a table that contains all your holders) and queries (e.g. find all my empty holders). It takes a bit of experimenting but it comes with the added bonus that you can backup your data...
