Overall the app works like a saximeter. The pros and cons of app are:
1. Report can be sent instantaneous to anyone.
2. Convenient and accessible.
3. Time and date accurately recorded.
1. Pile length, pile tip elevation, project info, and pile start depth can't be entered.
2. Mic volume is very sensitive and not getting set will give erroneous hammer stroke. A help guide for setting the mic would be helpful.
3. Pile logs can't be saved directly to recording device. Some locations don't have cell or wifi service, not sure if reports will save in email drafts.

Developer Response ,

Version 1.5.2 update has been released which allows the user to enter; pile tip elevation/depth, project info, pile type, structure, pile number, etc. Also, when working without data or wifi service the piles logs will sit in your email outbox until you gain access to wifi or data service at which time they will be automatically sent.

Great app!

Thank you for finally making an app like this! I love being able to save and email data. I checked against a saximeter and could not tell the difference. Worth every penny!!
