Looking to know the level of radioactivity around you and assess your exposure to ionising radiation? Thanks to this application, and a compatible sensor, you can measure radioactivity. You can also contribute to a citizen science project, by helping to create a collaborative data base of radioactivity measurements in the environment: OpenRadiation (published under an Open Database License). You will then be able to share your measurements using the application and view the data in the application or on the website www.openradiation.org. Create an account on the website www.openradiation.org, and obtain a compatible sensor (see the list of compatible sensors at www.openradiation.org). Activate Bluetooth under your mobile, configure your sensor to measure radioactivity, and publish your measurements. If you do not have a compatible sensor, you can always enter your measurements manually on the website or via the application. OpenRadiation currently brings together the following scientific and academic partners: IFFO-RME - training network in major educational risks -, IRSN - public expert in research and expertise on nuclear and radiological risks -, Planète Sciences – association contributing to the scientific and technical culture of young people - and SORBONNE UNIVERSITE Fablab - digital fabrication and rapid prototyping workshop, open to students, staff and the general public.
ToleranceLab
This app assists engineers in selecting and understanding ISO 286 fits for mechanical designs. It calculates clearance or interference based on nominal size and basis classes, providing visual representations of resulting diameters. The tool also estimates contact pressure and stress for press fits and includes a reference guide for definitions and recommendations.
- ISO 286 fit selection
- Hole/shaft basis class calculation
- Clearance/interference visualization
- Guided fit intent picker
- Press fit stress estimation
- Metric/imperial unit switching

ToleranceLab helps engineers pick ISO 286 fits and understand what those selections mean in the real world. Enter a nominal size, choose hole- or shaft-basis classes, and get clearance/interference results with a simple visual that labels the resulting diameters. Use the guided fit intent picker to match common engineering goals (free running, locational, transition, or interference) and jump into the built-in reference guide for definitions and ISO fit recommendations. When a press fit is detected, ToleranceLab estimates contact pressure and axial force using selectable compliance models and material data, with warnings and assumptions shown alongside results. Switch between metric and imperial units, explore fit classes quickly, and keep a practical reference at hand for design and manufacturing decisions. Disclaimer: ToleranceLab is provided as a general engineering reference tool only. All results and calculations are estimates based on standard formulas, assumptions, and user-supplied inputs. The app does not provide professional engineering, design, or safety advice and is not a substitute for independent analysis, validation, or review by a qualified engineer. To the maximum extent permitted by law, the developer assumes no liability for errors, omissions, or outcomes resulting from the use of this app. Users are solely responsible for verifying results and ensuring suitability for their specific application and compliance with applicable standards and regulations.

Verdict
The clearest difference is price: OpenRadiation at Free against ToleranceLab's $2.99. OpenRadiation also leads on update cadence (every 3 months vs every 8 months) and device support (3 vs 1). ToleranceLab's advantage is rating (5.0 vs 2.0). On ratings volume, ads and in-app purchases there is nothing between them.
