About

Kepler

Features
Read full description

The universe is the most patient narrator. Kepler is a sleep app built around a single idea: that the cosmos, told slowly, is the easiest place to fall asleep. Each night you open Kepler, you board a quiet voyage. A scientist walks you through the rings of Saturn. A long-haul astronaut describes the silence between Earth and Mars. A research station reports back from a moon you've never heard of. The narration is soft, unhurried, and deliberately a little dull — because dull is what your nervous system needs at 11:47 p.m. Stories are written for grown-ups, not children. No princesses, no dragons, no plot twists. Just slow movement through real and imagined places in space, with ambient cosmic textures underneath — solar wind, hydrogen hum, the low resonance of a quiet spacecraft. What's inside: • Original sleep stories, 5 to 6 minutes each — or 18 to 20 minutes for a full series • Narrators trained for the lower vocal register that helps you drift off • Ambient cosmic soundscapes you can listen to on their own • Sleep timer that fades out gently rather than cutting • Offline downloads for nights without Wi-Fi • Optional sleep tracking, off by default — your sleep is yours Kepler is not a meditation app pretending to do sleep. It's not a kids' bedtime app pretending to be adult. It's a sleep app, and its only job is to get you to the part of the night where you stop trying. If you've used other sleep, calm, or meditation apps and wished there was just one cohesive world to fall asleep inside — Kepler is that world. Space, every night, narrated to you. New stories arrive every two weeks. Premium voices and the full library unlock with subscription. The first three voyages are free, forever. Counting stars instead of sheep. ———————— SUBSCRIPTION DETAILS Kepler offers auto-renewable subscriptions that unlock the full library of sleep stories and premium narrators: • Weekly Access • Kepler Membership (monthly) • 3-Month Access • Yearly Access The subscription title, length, and price are shown in the app before you purchase.

Verdict

The call

The clearest difference is iOS requirement: Start 2 Run at 13.0 against Kepler's 15.1. On price, ads, in-app purchases and device support there is nothing between them.
