User reviews

Good Basic Collectors App

This app is great for basic functionality. I can keep track of my collection and it really does have basically everything needed. I would suggest two improvements: ability to upload more than one photo at once (you have to click and upload and then click again to upload another). Second suggestion is have the text fields automatically capitalize the first letter. Other than that, it’s good and does the job.

Response from developer

Thank you so much for the kind review and the helpful suggestions! We've just released an update that addresses both of them: • You can now select and add multiple photos at once from your library. • Text fields like mineral name, origin, and notes now capitalize the first letter automatically. If you have any other ideas or requests, we'd love to hear from you via Settings → Contact in the app. Happy collecting!
