No Trial Offer

Requires you to pay for premium version to see if it even works. Yes you can subscribe for a month and then cancel but most people won’t waste five dollars on something they can’t even see if the basics work.
Developer Response
Hi Mark, thank you for your honest feedback. We understand your concern, and we agree that users should be able to experience the app before committing to a subscription. We're addressing this in an upcoming update by introducing a free trial, making it easier to explore Screw Identifier before any purchase is required.

Pay Before Use
Hugh Br.
Developer expects $5 or $20 payment without allowing use of the app to see how it works. Useless.
Developer Response
Thank you for your feedback. We're sorry for the frustration. We understand that being asked to subscribe before trying the app isn't the experience users expect. We're addressing this by adding a free trial in an upcoming update, so everyone can test Screw Identifier before making a purchase. We appreciate your feedback and hope you'll consider giving the app another try after the update.
