Comments on Nuts & Bolts for Android

★★★★★ David Merriman · Feb 3, 2022

If all you need is the most basic info - clearance, tap, drill, etc. - for screws, this is the app. Don't know about any update (should, just to make the warning go away), but it seems to run fine; I mean, it isn't like the screws *mutated*, or anything. I'm fine with it, and thank the author for the time trouble. Update, and I'll spring for the Pro license.

Need to update more metric and inches sizes pitch calculation. Kindly update it. Otherwise, the app is good.

★★★★★ Fernando Fernandez · Apr 2, 2018

can you add this app to Apple App Store ? I change my phone from an android to a iPhone and can't be able to download from the App Store. Is very useful and I used every day. Please add to the App Store

I didn't find it useful. Was looking for an ap that would tell me the size of a nut ot bolt I am looking at

★☆☆☆☆ Roy Tellason · May 16, 2022

Just updated, and now it immediately crashes, saying "There was an error reading screw sizes". Removed it and re-installed, same behavior. Uninstalling...

★★☆☆☆ Mary Atkins · Oct 7, 2015

Cannot Zoom In Hard to see data. Unable to zoom in.

★☆☆☆☆ Santiago Arellano · Oct 29, 2022

Shows bolts but no nuts. Why call it NUTS and bolts when you leave out the nuts?

★☆☆☆☆ Christopher Redmon · Dec 17, 2017

Free app that's trying to get you to buy the pro version and has no nut sizing.
