Before you put it on your phone

What does it cost?
The first month is free. After that a license is $4.99 a year, and one key works on up to three phones.
Can I get it free?
Share the app from its Share button. Every friend who buys through your link gives you a free month, up to a year.
My agreement isn't in it.
Send it from the Settings tab (Send us your agreement). If the app doesn't have it yet, you get a free year when it's added.
Where do my hours go?
Nowhere. They stay on your phone. There's no account and no sign-in. The privacy policy lists the little the apps do send.
Does it need signal?
No. Open your trade's app in your phone's browser and add it to your home screen. After that it works with no signal, in the plant or out on the job.
What else is in it?
An hours log, a year view that adds up every paycheck, and a trade info tab: bolting and torque, flange charts, rigging or unit conversions, depending on the trade.
Is this from the union?
No. It's an independent tool built by a union tradesperson, and it uses no union logos. Check anything that matters against your agreement and your hall.
