The company describes its patented phase-locking technology as a form of "binaural beats 2.0" that targets the prefrontal cortex, where thinking and creativity occur, rather than only the lower brain. Users can adjust the intensity of this neural effect to match how much stimulation their brain needs. The catalog is organized by activity rather than genre. Modes cover Deep Work, Creativity, Learning, Light Work, and Motivation for focus, plus Recharge, Destress, Chill, and Unwind for relaxation, and Guided Sleep, Deep Sleep, Sleep and Wake, and Power Nap for rest. Tracks are long and lyric-free to avoid interruptions, and built-in timers support Pomodoro-style sessions, countdowns, and interval work. A dedicated ADHD mode adds extra stimulation for brains that need it. Brain.fm is available on web, iOS, Android, and desktop, and works with or without headphones. It offers a free trial before the paid subscription, and its research, including a study published in Nature Communications, is publicly documented on its science page. **Pricing & Plans:** Free trial followed by a paid subscription; the free trial lets new users explore the catalog and neural-effect settings before committing to a plan. - **Functional music modes:** Activity-based music and soundscapes for Deep Work, Creativity, Learning, Motivation, sleep, and relaxation, plus guided meditation and sleep sessions. - **Neural phase-locking:** Patented audio modulation designed to enhance and synchronize brainwave activity, with adjustable neural effect levels you can dial up or down. - **ADHD mode:** Higher-stimulation music designed for attention difficulties, backed by research supported in part by a National Science Foundation grant. - **Workflow timers:** Infinite count-up timers, countdown timers, and interval timers that adapt to focus and break sessions. - **Multi-platform access:** Listen on web, iOS, Android, and desktop, with or without headphones. **Strengths:** Backed by peer-reviewed research and a National Science Foundation grant; Modes mapped to specific activities rather than generic playlists; Lyric-free, extra-long tracks avoid distraction and repetition; Works with or without headphones across web and mobile **Limitations:** Requires a paid subscription after the free trial; The science and terminology can feel niche to casual listeners; Long-time Spotify users may miss familiar songs and artists [Profile (Markdown)](https://openaitools.app/tool/brain-fm.md) ## Onsen Onsen is a mobile AI companion built around mental and emotional wellbeing. The app offers 24/7 conversational support in a private, non-judgmental setting where users can talk about stress, grief, anxiety or everyday worries. Rather than a single chatbot screen, Onsen blends several modes of reflection: a chat experience, guided sessions that adapt to the user's patterns, an AI journal that turns conversations into written entries with mood analysis and generated artwork, and hands-free voice conversations. What sets Onsen apart is the structuring of emotional work into something trackable. Mood check-ins feed personalized recommendations, journal entries accumulate into a running narrative, and the app publishes outcome data from its own user assessments suggesting improvements in mood and stress over time. The tone throughout is deliberately warm and low-pressure, aimed at people who want support between therapy sessions, cannot currently access a therapist, or simply prefer to reflect privately. Onsen is free to download and use, with no credit card required, and adds optional paid features on top. It is available for mobile and also works across devices. It is a wellbeing aid rather than a clinical service, so it complements rather than replaces professional mental healthcare. **Pricing & Plans:** Free to download and use with no credit card required; optional paid upgrades and premium experiences are offered in-app. - **Personalized AI companion:** A conversational guide that adapts to your patterns, world and personal history over time. - **Guided experiences:** Structured conversations and prompts that help you navigate specific life challenges. - **AI journal with mood analysis:** Every conversation can become a journal entry with AI artwork, mood analysis and captured memories. - **Hands-free voice conversations:** Say your thoughts out loud and hear your AI guide respond for a natural, low-friction session. - **Privacy-first, non-judgmental space:** A private environment designed for honest reflection without pressure or criticism. **Strengths:** Warm, non-clinical tone that makes daily check-ins feel approachable; Combines chat, journaling, voice and guided sessions in one app; Free to download with no credit card required; Journal entries with mood analysis turn fleeting thoughts into a lasting record **Limitations:** Not a substitute for licensed therapy or crisis services; Best value features sit behind optional in-app purchases; Effectiveness depends heavily on how consistently you use it [Profile (Markdown)](https://openaitools.app/tool/onsen.md) ## Frequently Asked Questions ### How do Brain.fm and Onsen compare in monthly traffic?
