Viewing and workshop estimates

The app provides local CAD viewing and inspection tools. Dimensions, stone identification, ring sizing, geometry analysis, weights and casting costs are estimates based on available model geometry and your inputs. Check source units, material densities, stone classification, mesh validity and allowances with your designer or foundry before manufacturing or quoting. A “solid candidate” is not a certification that an object is manufacturable or free of cavities. Some 3DM files require saved render meshes. Only open files you have permission to use.

Free and PRO

Basic file viewing is available without a subscription. Optional PRO tools are described in the app. Android subscriptions are offered only when the plan is available through Google Play; browser previews and this iOS build do not offer checkout. Internal review access is for testing and is not a paid subscription.

Annual subscription

The Google Play checkout displays the applicable local price and payment details before you confirm. The annual plan renews automatically each year unless cancelled in Google Play. This version does not offer a trial or introductory offer. Cancellation stops future renewals and access normally continues until the paid period ends. Refund requests are handled under Google Play’s applicable policies and your statutory rights.

Use the same Google Play account to restore a purchase. Pending payments do not unlock PRO. Internet is required for purchase and subscription checks; previously checked access may remain available offline for up to 24 hours, subject to device and purchase verification. Reconnect and use Restore purchases if access cannot be checked. Free viewing remains available.

Manage or cancel

Use “Manage subscription” in the app or Google Play subscriptions. Removing the app does not cancel a subscription. For payment and refund help, see Google Play’s refund guidance.
