Barnaburn is the dog that closes your apps at bedtime. Pick your distracting apps and sign tonight's bedtime contract. At curfew, Barnaburn, a small and judgmental bedtime accountant, puts them behind a lock: CLOSED BY THE DEPARTMENT OF SLEEP. You get one emergency appeal per night. He files everything. In the morning, Apple Health tells him how you actually slept, and you get the Morning Report: your verdict, the evidence, XP earned, and a shareable Dream Receipt. Hit your sleep goal and earn levels, streaks, and awards. Miss it and receive a citation: a playful, fully recoverable offense you can clear with one good night. FEATURES - Shutdown Orders: your chosen apps close at bedtime and reopen at your wake goal - One emergency appeal per night, logged in tomorrow's report - Bedtime Contracts: sign tonight's terms (Reasonable, Ambitious, or Emergency) - Morning Report: last night's verdict, evidence, XP earned, and new awards - Dream Receipts: a shareable receipt for every night's sleep - Citations: rough nights get a playful writeup; one good night clears it with bonus XP - Case File: your sleep record, from commendations to repeat offenses - XP and levels: from Pillow Intern to Sleep Bureau Legend - Awards: a trophy case of 21 sleep achievements - Graphs: duration, schedule drift, and pattern insights over 7/30/90 days - Reminders: optional wind-down and morning check-in notifications that follow your goal - Barnaburn himself: an animated dog companion who gets visibly exhausted when you don't sleep - Works with Apple Watch, Garmin, WHOOP, Oura, and any device that writes sleep to Apple Health - 100% on-device, no accounts, no ads, and your data never leaves your phone App blocking is optional and entirely under your control. Barnaburn is a habit and motivation app, not a medical device. It does not diagnose, treat, or measure any health condition.

Verdict
The clearest difference is in-app purchases: Barnaburn at none against Prism's 1. Barnaburn also leads on iOS requirement (18.2 vs 26.0). Prism's advantage is device support (3 vs 1). On price, update cadence and ads there is nothing between them.
