App Introduction

Mechanical Engineering One stands as an essential aid for professionals and students in the field of engineering, during the design process, and in academic settings. Crafted by an engineer with engineers in mind, it aims to be a go - to solution for various engineering needs.

Key Features and Target Audience

Comprehensive Engineering Tool

Positioned as one of the most comprehensive engineering tools available, its main objective is to assist users in tackling daily mechanical engineering problems. However, its utility extends far beyond mechanical engineers. Naval architects, civil engineers, HVAC engineers, electrical engineers, and any individual, whether an engineer or a student, who frequently deals with common unit conversions and mathematical calculations can benefit from it.

User - Friendly Interface

Designed with a straightforward user interface, the app is highly practical for use in the field. Its simplicity ensures that users can quickly access the necessary functions without getting bogged down in complex navigation.

Diverse Functionalities

The application is equipped with a wide array of reference tables, calculators, and converters. Notably, it houses one of the most extensive unit converters on the market. All tools support both Metric (SI) and Imperial (US) units, providing flexibility for users working in different regions or with diverse project requirements. Whether it's solving problems related to the design, production, operation, or maintenance of machinery and equipment, or assisting in the design of tools, parts, and equipment across various industries, this app proves to be a valuable resource.

Applicability

While tailored for engineers, Mechanical Engineering One also serves as a useful tool for architects, scientists, technicians, and other professionals. Additionally, it is an excellent learning companion for students who are studying engineering, helping them grasp concepts and solve problems more efficiently.

    You bought Pro2.15 and now it's gone from the Play Store. You can’t update or install it on a new phone. You really enjoy the app. Makes you wonder if you should buy it again. It’s tough when a favorite app disappears like that. You might want to check with customer support for possible solutions. Perhaps they can help you access your purchase again.

    I reset my device and tried downloading the app again. I can't find the pro version now. Can someone help me out? I’ll leave a five-star review once this is sorted!

    I searched for the pro version in the Play Store. It used to be there. Now, it’s missing. I really need some help finding it. Still searching but no luck.

    The effort involved is significant. The user interface struggles to impress. Many necessary data points feel missing or hard to find.

    I found exactly what I wanted! The app has great potential. Adding more standards like ASTM, EN, IS, JIS would really enhance it. A better-categorized user interface would make navigation easier too.

    This app is indeed very useful. It is available on the iOS platform. You can find it by searching for its name in the App Store. If you’re looking for a different app or one that isn't yet released, there might be plans for a future launch. Stay tuned for updates!

    The unit conversion is just a chart, not a calculator. It doesn’t really help with convenience. The material specifications seem decent, but the bolt clearance fit lacks size information. That makes it harder to work with.

    This app was amazing. I don't understand why they removed the pro version. I sent an email, but no one replied. I'm in the middle of a machine design project for class. It's frustrating because the built-in calculators would help me verify my work quickly.

    You bought the app a while ago? That's great! Since you've changed your mobile, you can usually download the pro version again without paying again. Check the app store on your new device. Log in with the same account you used to purchase it. Look for your purchase history or the "My Apps" section. You should find the pro version there. Just hit download. If you run into any issues, customer support for the app might help you out too. Enjoy the app on your new phone!
