A bit of a heads-up, that I hope may help someone. I've been looking for a simple cataloguing app for awhile and most seem to have followed the pay-to-use model (annual subscription), be exorbitantly expensive (wanting payment based on amount of items you catalogue) or be overly complex (often trying to pre-populate the database with existing product lines or having a myriad of pointless tabs). My goal was to find something that allowed for basic information and to assign a photograph to each piece of a collection. Yesterday I stumbled across 'Collector One', which really is the digital version of a simple card cataloguing system. Unfortunately, it is buried deep within the iTunes shop and therefore, isn't an app you stumble across unless you were willing to scroll through pages of promoted, irrelevant, software. Firstly, you can set up multiple collections - for instance a catch-all like 'Sofubi' or, if you'd rather, drill down into genre you can do that. Once you've set up the Collection heading, you can start adding items (here are a couple of sample shots - which are not as crisp as the app is because of re-sizing them to post): In simple terms, you can Name the item, write notes to describe it (I've used this to denote source of original sale: festival, lotto, dates, etc), additional information (price (good for insurance purposes) or anything else you deem relevant and lastly, you can create categories and groups within the collection, which I have used for maker. Once populated, you can search on any keyword, via the list of items or refine by the category or group: The developer is open to feedback and I've made three suggestions: 1) it would be nice to have a dedicated price/value field 2) multiple photos per item would be helpful to allow headers to be photographed alongside the toy 3) a way of exporting the data, so that you can preserve a hardcopy He has already confirmed that an export function is something he is currently working on and the aim is to export in CSV and also PDF. I paid circa $5.00 for the app and that seems very reasonable to me. Given the previous conversations on here about what could/would happen to people's collections on here should something happen to the individual (legacy and understanding value) or how to approach an insurance claim should you be in the unenviable position to have to make one, this seems like a simple solution.
