Pinch in on the details. - Sound clips recorded right in the app. Capture how it sounds today, fresh strings and all. GUITARS AND BASSES, YOUR WAY - Search, filter and sort the whole collection. - Keep the ones you've sold on record, marked as sold. - Works on iPhone and iPad. SHARE A SPEC SHEET - Turn one guitar or the whole collection into a PDF spec sheet, ready for Mail, Messages, Files or Print. - Choose what goes in: the main photo, details, specs, setup and ownership notes. - Handy when you're insuring a guitar, selling one, or just showing off. YOURS, AND PRIVATE - No account to make. - Your collection syncs between your iPhone and iPad through your own iCloud. - No ads and no tracking. The app sends anonymous usage statistics only, never linked to you. PAY ONCE One purchase. No subscription, no in-app purchases. UPGRADING FROM 2.x? Ax Collector 3.0 is a complete rebuild.
