Hopster vs VideoLectures.NET

Hopster is an ad-free app for preschool children, combining learning shows, games, books, and songs in a child-navigable tropical island setting. Its apps are designed for ages 2–6, and the content aims to support literacy, numeracy, social-emotional learning, and creativity. Children can download favourites for travel, including shows, games, and songs. Video viewing is paced through limited autoplays, alternating videos with a book or game, and a suggestion to try another activity after three episodes in a row. Parents can receive a monthly report on what children watch, read, and play. Hopster also offers exclusive Hopster Originals. It runs on Android, iOS, and the web, and offers a seven-day free trial but no free plan. Subscription prices vary by selected plan and region, and subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the period ends. Hopster says its apps comply with COPPA. Its privacy policy says payment providers process financial data, which Hopster apps do not collect, store, or access. The company trades as Plato Media Limited and has offices in London, UK.
