Hopes were high but upon opening it said app was developed for an earlier android version and may not work properly. Minimal valuable data in the free app but can't justify purchase if it's not current. Latest update appears to be 2012? App should be removed from playstore.

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

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

Only a very limited selection of screws. Doesn't have any information about obscure ones.

Useless without the pro version. No way of telling if it's worth the buy.
