Hey Product Hunt! I’m cena, the solo maker behind WhatsFeel. Like many of you, my brain refuses to shut down at night. I tried standard meditation apps, but listening to the exact same static, pre-recorded 15-minute script stopped working after day three. My heart rate would still be racing, but the static narrator just kept talking at its own stubborn pace. I realized: The app shouldn't dictate my body's pace; my body should dictate the app. So I built WhatsFeel—a fully AI-driven meditation, sleep, and relaxation app. Instead of playing static MP3s, it connects to your real-time heart rate via Bluetooth and dynamically generates every single line of spoken guidance to bring your nervous system down. Inside the app, you get 4 specialized AI Companions: 1. Nature Sounds : High-def ambient soundscapes (rain, campfire, birds). Play them standalone or layer them behind your AI sessions. 2. Meditation Coach: Continuous AI spoken guidance. It reads your heart rate and intelligently shifts the topic whenever your focus drifts. 3. Sleep Coach: Can't fall asleep? This agent delivers gently evolving, soothing bedtime talks tailored to lull you into deep sleep. 4. Chat Companion (100% FREE): A dedicated safe space to vent your daily stress, anxiety, or emotional burnout anytime. A few things we built specifically for this community: True Hardware Freedom (0x180D): We don't lock you into Apple Health. We support standard Bluetooth GATT Heart Rate profiles—whether you wear a Garmin, Polar, Coros, or a generic chest strap. Zero Health Data Storage: Your real-time heart rate is processed strictly on the fly to optimize the live script. We never store your biological stats on our servers, nor do we sell or harvest them. Transparent, Fair Pricing: Free: Unlimited access to the Chat Companion. Basic Monthly: Unlocks AI Meditation & Sleep Coaches. Premium Monthly: Unlocks live Heart Rate sync + Custom Voice selection. We are live on both platforms today: 👉 iOS: https://apps.apple.com/us/app/wh... 👉 Android: https://play.google.com/store/ap... Being a Day-1 launch as a solo dev, I’m mentally prepared for bugs! I’ll be hanging out in the comments all day answering everything. My question for the makers here: When you're stressed out, do you prefer guided spoken words, or just pure nature sounds? (And for the fitness geeks: did your specific BLE watch/strap pair smoothly?) Thank you so much for checking it out!
