This website is designed to be run on a wide screen monitor with a typical computer, where the multi-frame design works best. However, it can be used on a mobile device, but restrictions may apply because of screen size.
If a computer is not available, it will work perfectly well as it is on a tablet (and perhaps on a phablet or mobile if the number of screen pixels is sufficient). The web-browser 'Puffin' should be installed, as that is the only web-browser for mobile devices that your Author has found which will allow independent scrolling of the frames (which the WildFlowerFinder website uses to such great effect). If your mobile web-browser scrolls the whole set of frames up at once (instead of each frame independently), then install and use Puffin, which will work fine (except that the last frame, the Subject Index, will be absent). Your Author does not know why this last frame is absent on Puffin (he has written and asked them thrice without response), but you dont really need the Subject Index on a mobile device when you can see the first three frames, and it allows the first 3 frames more screen-space.
There is no mobile phone app for this website; it occupies many more MegaBytes than the maximum storage which can be allocated to any app. And, in any case, an app would not be updated with new items anywhere nearly as often as does this growing website. But you can view the critical index or menu pages separately on a mobile phone, small tablet or PDA from which the reader will be able to access possibly 99% of this website on a small screen.
But the small screen sizes (both physically, and perhaps in pixel count) typical of mobile phones means that it may have to be used just one column at a time; a sub-set of the Wild Flower Finder website.
The choice of which menu or index to use depends on what you want to find. It is therefore best to save a selection of differing menus and indices on your mobile device. Such a selection can be stored as URLs on your mobile or PDA, which, when clicked upon, will open up in your default web-browser (such as Safari, Firefox, Internet Explorer, Netsurf, Opera, Chrome, Puffin, Lynx, Mozilla, Netscape, Edge, Mosaic, Phoenix, Browse, Dolfin, UC browser, etc - although some web-browsers will be much better than others) and run the menu or index. Clicking on one of the items in the menu or index will take you to the page on the main website which you have selected.
SUGGESTED URLs TO SAVE ON YOUR MOBILE DEVICE:
This is an extremely powerful search function especially suited to searching and helping identify wild flowers in the field on narrower screens. To help you enter the URL, simply photograph the Mobile QR code at the top with your mobile device, possibly into Google (the mobile app) [which accepts images, rather than Google > images which does not]. 'Puffin' is web-browser capable of independent scrolling of frames on mobile phones and tablets; most other mobile browsers cannot do this.
Or you can enter the following additional URLs manually into your web browser, and then 'Save To Home Screen'. Simply clicking on one of these saved URLs will instigate your default web browser and display the said menu. Clicking on an item in that menu will hopefully take you to the page you want.
A-Z SUBJECT INDEX
(this last URL will save you scrolling an enormously long way through the
subject index if you didn't want a word beginning with 'A', if it works reliably...
[on your Authors mobile it only sometimes works, but mostly doesn't for some unknown reason! - And yet this same URL works perfectly on his computer. It must be a quirk of his mobile])
If this last URL works (it doesn't on your Authors mobile for some unknown reason) it will allow access to many (not all) 2nd-column menus,
such as the chemical structural formulae, list of hybrids, list of
poisonous plants, list of secondary metabolites, list of dye plants, list of smelly plants, list of
all the INFOs, The APPendix list, list of Families, etc.
If, when using the saved homescreen URLs, the selected page does not appear, it could be that it has been served on your device underneath the URL menu you are using to select it. In which case, press the icon which allows you to see all the pages that are in your web-browsers memory, but are underneath everything (on an Apple mobile device this is the empty square icon), and select the page you wish to view.
Your Author does not think there is a work-around to this other than doing as described; the main website is not designed to serve up pages from menus on top of the menu it was selected from, but rather into a differing window. So, the user can hardly blame their mobile device if it doesn't know where to serve the selected menu item, and just shoves it underneath their present page~
