If you need help to fall asleep this is the right APP. I have recorded cowbells, crickets and birds in the Swiss mountains. I used a 4-channel microphone to record these sounds. I remastered these recordings in a high definition m4a format. You can use them as background sound from 3 to 59 minutes. The sounds will fade out at the end. Happy sleep! Select the background sound from cowbells, birds, crickets and brook Select the minutes before the sound will fade out This APP works in the background. 4 channel Dolby recording in Switzerland Grindelwald

ByeByeSugar helps you break the added sugar habit with one simple system: commit to a challenge, check in every day, and stay accountable. No calorie counting. No meal plans. No endless tracking. Just a clear goal and a daily check-in that keeps you honest. How it works * Choose a 7, 14, or 30-day challenge * Spend credits to start and make the commitment real * Check in each day to confirm you stayed off added sugar * Finish the challenge and earn your credits back so you can keep going Daily Briefings * Every day, you get a short, evidence-based briefing on what added sugar does to your body, tailored to your goal. Briefings are built from trusted sources such as the CDC, WHO, and peer-reviewed research. Achievements * Unlock badges as you build consistency, see how rare each one is, and share the milestones youβre proud of. Clear sugar rules * ByeByeSugar focuses on added sugar, not naturally occurring sugar. Whole fruit, plain milk, and similar foods are not the target. The app gives you clear rules so you always know where you stand. Built for focus * No social feed. No subscription. Just a challenge, a daily check-in, and a reason to keep going. Start with 2 free credits. Your first challenge is on us.
