Great useful app with some small errors

The app is very useful and convenient to use. I would give it a 5 star review, if it wasn’t for a few errors that can be easily rectified.
For metric bolts of class 10.9 and 12.9 the proof strength is lower than what’s specified in the standards. Additionally, the calculation of the tensile stress area for all metric bolts is a bit off. Those two factors together leads the app to suggest a torque figure that’s lower than it should be. There’s an error in the tensile area calculation for SAE bolts too, but here it’s small enough to not really affect the suggested torque.

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

Great App for a hobbyist

I’m a hobbyist who machines and fabricates for my own projects. This app is very handy for me. It saves me from looking up screw dimensions in handbooks and walking to where I keep a drill chart. I do wish it had a tap drill table, that’d save me even more time. I read a review which mentioned tensile strength of some fasteners being different than other references. I haven’t compared those in the app to other references. I only use the dimensions and haven’t, so far, found any discrepancies. Good eye to the reviewer who caught those.
