I recommend using
1. FlexiSPY
2. mSpy
3. Spyic
4. Where's My Droid
I am using these, in which some are paid, but if you get them through any discounted store you will get discount as I got them through Reecoupons by using SCDKey Coupons, and I got a huge discount, so you cant say that it's very costly, there are many others are available too, if you wanna buy check once on there.

Thanks for your response, but I'm looking for time tracking.  I'm using T sheets and it is hard to monitor and adjust, plus the cost is going up.
