I use it almost daily for different tap and drill bit sizes. Great for torque ratings and showing the strengths of various materials.

This is one of the most useful of the 'engineering apps'. An enormous amount of data is made easily accessible and presented in a way that gives as much, or as little, as you need.

Use daily. Very handy for torque setting and for fabrication work. Not named correctly. Only found by referral.

Intuitive interface with access comprehensive catalog of technical data for imperial and metric threaded fasteners. As others have noted, the title of the app is far too inclusive considering the focus on threaded fasteners but that doesn't take away from the tremendous value the app delivers. The last time I upgraded my phone iEngineer was the first app I reinstalled. I don't think there's anything better for engineered deign professionals or students.

I've had this app a while. After not being updated for 2.5yrs, it's still stable & works well. I do believe a freshening up of the UI to correspond with the larger handsets (6+, 6s+, 7+) would be nice as the app is starting to look a little poor on the larger screen. Hardly bad enough to be upset about having it or purchasing the Metric add-on.

Awesome app! Use it everyday, has all the information I need, drill and tap sizes, clearance holes, loads, head sizes and more. Very easy to use, sure beats old reference cards or opening up the machinist handbook when you need a quick reference.

3 star=I like the app... In my humble opinion this has real potential to be a winner. We interrupt this profession of humility with an important yet judgmental review: This was designed by a student engineer with little to no practical application of textbook data wasn't it? C'mon.... It's full of superfluous data that just ends up cluttering the display for about 95% of all skilled tradesmen in the field. On the other hand it's much easier to reference than your text during an open book exam. Yep, you guessed it, I'm no engineer and yet I downloaded an app, in that professions namesake. Joke's on me... Still, for profitability sake, there are more skilled tradesmen than engineers anyway so why not market to them first? e.g. The calculator apps that are basic and scientific when rotated or mode select 1. Why didn't you include a hex flange head in the mix? That's like a margarita without tequila. Don't say it's the same as hex/washer because you better know better. 2. Substrate data anyone? Composites, steel alloys: ferritic/austenitic/martensitic; non-ferrous alloys you get the idea. If I'm going to fasten two identical materials, this will be enough. Unfortunately, it just never works out that way in the thunder dome. 3. Bolt Finish?- phosphor, zinc, chromate, cadmium, Jedi Juice... pertinent factors
