GST[AR] allows you to browse, download, view, and share geological models in augmented reality. Browse Browse through available models and their features to find a nice selection to present in AR. Models are retrieved from running instances of GST Web. Don’t worry, there are default sources added already, so you can get started right away. Hint: If you see a „Visit“ button near a section of models, you can tap it to learn more about the institution that provides these models for you! When you select a model, you will find a list of features waiting for you. Make your selection and off you go to the AR view. View As soon as the features are downloaded, you will be able to place them on any horizontal surface in AR. Use gestures or sliders to rotate and scale your model. Tap on individual parts to learn about their name or use the legend to even highlight individual features. Superelevation is available via sliders as well! Share When you have placed a feature selection in AR, you get the option to share your session with others! Use the share button to let other peers join your session, synchronize your worlds and you will be looking at the same model in no time. Changes to the model rotation, scale and location will be synced automatically between all peers in the session. Hold down on a model to place your marker to point towards the feature of interest or highlight a certain feature via the legend for all other peers. Settings and customization Customize your experience by changing a couple of settings. In the settings menu, you will have the possibility to change aspects of scaling, how high the models float above the surface or even enable such cool features like "people occlusion" that make your AR scene even more immersive! Furthermore, if you want to access models from a GST Web instance that is not present in the app, you have the possibility to add endpoints of your own. ## Key features - Browse geological models - View models in AR - Rotate and scale models - Highlight model features - Share AR sessions - Customize AR settings - Add custom model sources ## Frequently asked questions about GST[AR] ### What is GST[AR]?

GST[AR] has an age rating of 4+, making it suitable for a wide range of users, including younger learners interested in geology and AR. ## Version history (last 5 releases) ### 1.2.0 — 2026-05-27 It took a while, but GST[AR] finally makes use of Liquid Glass on iOS 26. Now you see more of your models with less space occupied by the user interface, especially on iPad. ### 1.1.8 — 2025-11-11 With this update the gesture to rotate the model has been changed. Now you can rotate the model by dragging horizontally with one finger. That should be more intuitive and easier to use while holding the device with one hand. We have also fixed a couple of issues with this version: * Fixed an issue where the model would not appear in the same location in collaborative mode * Fixed an issue where the rotation of the model would sometimes appear flipped * Fixed an issue where the AR view would not show correctly after scanning a QR code on iPad * Fixed an issue where the AR view would suddenly disappear on iPad ### 1.1.7 — 2025-10-15 We have updated the minimum required version of iOS to iOS 15. This allows us to use a couple of new features under the hood and prepares GST[AR] for the future. ### 1.1.6 — 2025-09-02 We have made some improvements to how the Z-offset is handled. You can now dynamically change it inside the AR view by swiping up or down with two fingers. This will also be synchronized in collaborative sessions! We have also added a little info dialog that explains this gesture and all the other ones that are available. Additionally, the app will now keep track of which QR code you scanned last, making it easier to reload a previously opened model again. We hope you enjoy using GST[AR]! ### 1.1.5 — 2024-10-18 Have you ever tried to convince a friend to try GST[AR] but they didn't want to download the app first? That will no longer be an issue because, with this update, we officially support app clips! This means that anyone with an iPhone or iPad can simply scan a QR code to download and view a model without going through the App Store first. Keep an eye on our blog, where we will provide more information on how to use this for your own website, conference poster, or presentation. Furthermore, we won't abort the download process if one or more features cannot be accessed. We will simply visualize the features that could be loaded and, optionally, provide some information about any errors. We hope you enjoy using GST[AR]! ## Apps similar to GST[AR] | App | Rating | Price | Category | | --- | --- | --- | --- | | [GMDE Lite](https://appshunter.io/ios/app/gmde-lite/id1557325241) | 5.0 (2) | Free | Education | | [FaultKin Mobile](https://appshunter.io/ios/app/faultkin-mobile/id1234264776) | 5.0 (2) | Free | Education | | [Geology Dictionary - Offline](https://appshunter.io/ios/app/geology-dictionary-offline/id1488197434) | 3.4 (5) | Free | Education | | [Soil Explorer](https://appshunter.io/ios/app/soil-explorer/id996159565) | 4.4 (7) | Free | Education | | [DeepTime for Geology](https://appshunter.io/ios/app/deeptime-for-geology/id1500200416) | 5.0 (7) | Free | Education | | [Rockd](https://appshunter.io/ios/app/rockd/id1153056624) | 4.4 (183) | Free | Education | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
