Ive been using this ap for about 2 years. I love it, I use it on every job. There are a few glitches here and there but when I contacted the company I got an email back within 24 hours addressing the problem. A few hours later a follow up email came saying that they had fixed the problem and had submitted the update to apple. I give them 5 stars for customer service!! 4 on the ap because its not quite there yet, but they are working on it. One other fix... it would be nice if you could set it to subtotal weeks instead if only the entire job.
