Iherp is good I have used it but my problem is I get very busy at times and starting the computer means I have to go back to work. I found in my life I put it off and them got behind same for my book I used. The best thing of the reptile scan is I scan the bar code thing it builds for you with my phone and it registers the animal and I use the drop down to record the action. Done. For me it works better than others. Every method is different and everybody's needs are different too. My note book worked great when I was only working 40 hours a week when I hit the 65+ it stopped working well. What is perfect for one person may not work for the next. Look at as many variations as you can and use the one the works best for you.
