Operate devices compatible with BlueSecur using the Berner BlueSecur app. You can send permissions (keys) to family or friends, for example, via text message, e-mail or messenger. You don’t even have to be home to send a key, since keys are transmitted via a certified server in Germany. Manage your keys right in the app. The BlueSecur app must be installed on your mobile phone ahead of time. If a user hasn’t installed the app, they will be forwarded to the app store. Information on the BlueSecur app: - Add a device by scanning the QR code. - Setup and operation do not require an Internet connection. - Permissions (keys) are created on the administrator’s app, can be issued either temporarily or permanently and can also be deleted. - Sets of keys are subject to a fee. One-time keys are free of charge. - Max. 250 users - Optionally, you can use an external antenna should you have range issues. Using Bluetooth in the background of your mobile phone reduces its battery life.

About

3D Topology Optimizer

Features
Read full description

3D Topology Optimizer reduces the weight of a 3D part without sacrificing its strength β€” entirely on your device, with no cloud upload required. Load an STL model, mark contact surfaces, applied loads (forces and moments), and functionally important faces that must never change. The app then runs a real finite-element simulation and a SIMP topology optimization directly on iPhone, iPad, or Mac to determine which material actually contributes to strength and which can be removed. FEATURES β€’ Automatic hole detection β€” cylindrical bores are recognized and automatically protected from the optimizer β€’ Calculated entirely on-device β€” your geometry and load cases never leave your device β€’ High-resolution STL export for 3D printing or CNC machining β€’ Built-in parametric templates (bushings, brackets) to get started without any CAD file β€’ Wireframe and shaded 3D viewer with axis indicators for precise face tagging WHO IT'S FOR Engineers, product designers, makers, and students who design 3D-printed or CNC-machined parts and want a fast, private way to see where material can be safely removed before committing to a print or a machining run. All calculations are a simplified, linear finite-element approximation and do not replace certified FEA software or review by a qualified engineer. Always verify results independently before manufacturing load-bearing parts.

Verdict

The call

The clearest difference is ads: Berner BlueSecur at none against 3D Topology Optimizer's shown. Berner BlueSecur also leads on iOS requirement (14.0 vs 17.0). 3D Topology Optimizer's advantage is update cadence (every 6 days vs every 5 months). On price, in-app purchases and device support there is nothing between them.
