Norton Family Premier is cheaper ($49.99 per year) than Qustodio and does not limit the number of devices you can monitor. The biggest difference is in the pricing. These products have similar features to Qustodio for Families. Qustodio for Schools aims to keep students on track when using school computers, while Qustodio for Business is designed to make sure employees are working, not watching cat videos-or worse. Some advantages these plans offer over the free version are up to 30 days of activity history, application-based time restrictions, and location tracking. Qustodio structures its paid subscription plans around family size, with Small (five devices), Medium (10 devices), and Large (15 devices) options. You also get basic controls like web filtering and time quotas for certain activities. The free version limits monitoring to just a single device and only keeps seven days of activity history. Qustodio for Families is expensive, but it does have a permanently free option.
