UCB Spark – The BRAND-NEW devotional app for kids – has landed! WHAT’S SPARK ABOUT? Life can be a rollercoaster. Whether things are going great or you're going through something tough, the Bible has great advice for navigating it all. At UCB, we’re all about sharing God’s Word, so we created UCB Spark – a video-based devotional app designed to help you dive into the Bible and connect with it every day. WHO’S IT FOR? Spark is designed for 10-12-year-olds, but if you’re a bit younger (or older), you’ll still find something just for you. WHAT’S IN IT? Every day, there’s a new short Bible-based video to watch. Whether it’s a UCB Radio presenter singing wildly off-key, virtual boxing matches, or lightning-speed special effects, each day we’re diving into big topics like identity, bullying, friendships, and much more. Each video is followed by simple activities related to what you’ve just watched. It might be questions to think about, a hidden Bible verse to uncover, a prayer, or another activity to help you connect with God in a real way. Even on days when you’re feeling distant from God, Spark has something to remind you that you’re loved and seen. Let UCB Spark help to ‘spark’ a love for the Bible in you. FEATURES - A new video every day from UK content creators. - Choose from topics like friendship, identity, and more. - ‘Surprise me’ – let the app pick a devotional for you. - Set daily reminders so you can remember to ‘Spark’. - ‘Scrub to reveal’ – reveal the Bible verse by scrubbing the screen. - Drag-and-drop Bible challenge. - Share your thoughts with emojis. - Captioned videos. - Share the app with a friend.
