Market Compass is an iOS market briefing app that helps long-term retail investors get context, not noise - in just a few minutes a day. It turns a small set of core signals (sentiment, macro conditions, and equity structure) into a clear daily read on whether markets look more like Opportunity, Transition, or Stress, plus an Opportunity Score (0–5) designed to support disciplined “buy weakness vs. step back” decision-making. Built for iOS: Works seamlessly across iPhone, iPad, and Apple Watch

I started this app as a simple timer for my own boxing workouts. Now it is evolving into a digital corner coach, thanks to recent advances in AI and a lot of late-night vibe-coding. If it helps you move, punch, sweat, or smile — mission accomplished!

Best Text to Speech (TTS) API for expressive and realistic voice over?

Hi everybody. I am currently searching for the best expressive text to speech model for my app. Two years ago I used the Google TTS API which is pretty decent but does not come with the type of expressive emotions that I envision for my apps. Any suggestions regarding a good TTS API? What about Hume AI, ElevenLabs or rime?
