I recommend HiMama
I get to see the activities my daughter has done throughout the day and also get to watch some pictures and videos as the daycare posts. That is really a great feature. Apart from that I have see the application itself is pretty easy to use and I like the milestone feature where I can record my daughter's milestones. Apart from few slowness experienced with the websites at times (very rare though), do not have any negative comment about the website. It is really good.
