Model Inventory 4+

Whilst an excellent idea, this app reeks of version number 1. Or less.
Repeatedly entering the same data is a mindless time waster - at least in Excel I can copy and paste.
Inability to even edit a category is frustrating.
Should be able to load multiple pictures for each loco or piece of rolling stock.
Also should be able to define the scale at the start of a collection - re-entering the same scale each time is tedious, for several thousand of items.
Support for Australian model manufactures (and other countries) could easily be preloaded.
Woodland Scenics is a respected brand in the model railway game - this app is not a representation of that earned respect.

The concept is good abate a little bit tainted by the "Woodland Scenic" tie in.
For Marklin junkies like myself you are reduced to virtually entering everything much the same as one would in "Excel" hence I can't say this is much use to me as I can achieve the same in Excel with less hassle.

If it wasn't a freebie I'd be rather miffed, stick to Excel or if your so inclined try to do something in Access and get exactly what you need.

However no doubt if all your rolling stock/track/buildings are US based then this would be great, totally useless for European gear.

Helpful and easy to use.
