About

Bedtime Stories

Features
Read full description

Fall asleep with a sleepy AI chat instead of endless doomscrolling. SleepTower is a calm evening companion: it tells boring stories, overexplains simple things and drops unfunny jokes on purpose β€” so your brain finally gets tired and lets you go to sleep. Replace doomscrolling with a sleepy ritual Instead of checking β€œjust one more” post, open a quiet chat made for night time. SleepTower helps you: β€’ switch attention away from social media β€’ slow down thoughts before bed β€’ build a gentle digital detox routine β€’ fall asleep with something soft and predictable in the background Three sleepy AI modes Choose how you want to unwind tonight: β€’ Boring story – long, calm stories about everyday things with too many details and no plot twists. β€’ Explain it boringly – tedious explanations of simple and complex terms, with slow examples and repetitions. β€’ Unfunny joke – flat, overused jokes that are explained afterwards until they stop being funny at all. All replies are designed to be safe, non-triggering and a bit dull on purpose. Adjust your boredom level: Some nights you need just a light slowdown, other nights you want maximum β€œbrain off”. In SleepTower you can: β€’ choose the intensity of the β€œboring” mode β€’ set session duration before bed β€’ gently guide the assistant to match your current mood Track your progress: SleepTower also supports your digital detox journey: β€’ profile and achievements for evenings without social media β€’ streaks and statistics of your calm nights β€’ small goals that help you stay consistent with your bedtime routine Made for reading in bed: β€’ minimalist dark interface β€’ comfortable fonts for low light β€’ works great on both iPhone and iPad Subscriptions: SleepTower offers three auto-renewing subscription options: weekly, monthly and yearly access to all sleepy chats and features. Subscriptions renew automatically unless cancelled in your App Store account settings. You can manage or cancel your subscription at any time. SleepTower is not a medical app and does not replace professional help. It is a gentle, slightly boring AI companion for anyone who wants to scroll less and sleep more peacefully.
