#956A hybrid between forum and (headless) CMS, with customer support tools built in, so people can build websites that are kinda like posthog.com without having to patch everything together from scratch (and instead focus on their actual product AND not lose their community content in slack/discord/whatever).

#957Sereze guides personalized breathing techniques like Box Breathing, Yoga Nidra/NSDR, and Silent Meditation, tailored using your Apple Health data (HRV, HR, sleep). It works completely offline with no logins or server sync — just phone and your Apple Watch.
It tracks heart rhythm and variability in real time during sessions, then uses LLM/GenAI to offer personalized insights into your nervous system health, sleep recovery, and stress resilience. You can even ask it questions post-session and receive contextual responses.
Recent features include TTS-guided breath cues, REM/Deep/Core sleep stage breakdowns, and a silent mode for mindful journaling or meditative tracking.
Would love feedback or collaborations! https://apps.apple.com/us/app/sereze/id6736566597
