Ratings and Reviews
The glass is half bull
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
Thank you so much
App has been updated and now works with IOS 11. Thank you for the update. I believe that this is the best app available for this source of material. I downloaded another similar app. For a much much higher price and while it may prove useful it falls short when compared to iEngineer. This app is quicker, more user friendly and has much more selections.
I highly recommend this app if you work with design, engineering or maintenance daily.
I’ve been a user for years and can’t imagine working without it.
I have been using this app practically since it was first released. It is the best app for getting all the info you need about bolts and screws - including metric ones. The clean interface has been made even better with the iOS 11 update. It is no a machinist bible and does not pretend to be one. If you just need info on a bolt, what through hole or tap hole to drill, fraction to decimal conversions, etc. this is the best you'll find.
