Blub

A bedtime science podcast for ages 4-9. How do airplanes fly? How does the brain work? Why do volcanoes erupt? On Blub, two narrators explore these questions in conversation, with no screen needed. A PODCAST EVERY NIGHT Choose your child's bedtime. Blub reminds you at that time every night; tap the notification and tonight's podcast opens straight away. Dim the lights and listen together. Audio stops on its own when the podcast ends, so you can turn off the screen. If it's not finished, it picks up where you left off the next night. ASLEEP CURIOUS, AWAKE WITH QUESTIONS Your child drifts off thinking about what they heard. At 6:30 the next morning, we send you a question to ask at breakfast, so last night's topic becomes a conversation at the table. If you didn't hear the podcast yourself, the answer is right there in the app. YOUR FIRST PODCAST IS FREE When you start, we ask your child's age and interests and pick the first podcast to match. Listen to 45 seconds first. If it's not a fit, pick another topic. The first podcast your child likes is free in full. 8 SERIES, FROM SPACE TO THE HUMAN BODY • Little Scientists: planets, black holes, light and colors • Our Body: the brain, the heart, muscles, the senses • Nature and Earth: volcanoes, earthquakes, tides, seasons • How It Works: telephones, the internet, electricity, computers • Everyday Science: airplanes, rain, ice, soap • Super Vehicles, History Mysteries, Geniuses Who Changed History Each podcast is about 15 minutes. PARENTS STAY IN CONTROL • No ads, no chat, nothing for your child to look at. • Change or turn off podcast time and morning questions in Profile. • A quick rating after each podcast helps us pick future nights your child will enjoy. • Available in English, Turkish and Spanish.

Verdict
The clearest difference is update cadence: Blub at every 3 days against ActivityRoots's fortnightly. Blub also leads on iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
