I like that you can create your own custom experiences to fit each individual's needs/interests! You have so many options from which to choose; it is very helpful when trying to figure out what type of experience would be best suited towards my clientele in terms of their interests as well as age demographic.
The only thing about this program we don't really love too much at all is how long some pages seem to load (especially if they are quite large). This could just be due to our internet connection but other than that there isn't anything else we dislike or didn't enjoy using yoActiv either! Creating an activity schedule with yOaC has been extremely easy through creating different schedules depending upon the day of week etc. It also allows us to keep track of who attended by simply looking up dates rather than having to manually write down names & phone numbers.
