BECoach.ai vs Certly

Edge model, born to be cutting edge. BECoach.ai is the world's first iOS app to run Qwen3.5 — Alibaba's most advanced AI — entirely on your iPhone. No cloud. No server. No API. No data leaving your device. Just pure, private, on-device intelligence. The Transformation Economy We are entering an era where personal transformation is the most valuable commodity. But here's what most people miss: the fastest way to learn is to teach. Coaching isn't just for the person being coached — it transforms the coach. Every great teacher will tell you: you don't truly understand something until you can explain it to someone else. Coaching is learning by teaching, in real time, with real stakes. It compounds. The coach grows. The student grows. The community grows. But coaching is expensive. A great coach's time is finite. Most people who need one will never have one. This is where AI changes everything — not by replacing coaches, but by multiplying them. BECoach.ai isn't designed to coach without humans. It's designed to make human coaches more effective, more prepared, and more present. It handles the thinking partner role between sessions — so when a coach shows up, they show up for what only humans can do: presence, empathy, accountability, relationship. AI supports the coach. The coach transforms the person. That's the model. Born from a real idea Last summer, a coach sat by the pool watching his kids swim, chatting with AI about what the future of coaching could look like. He registered becoach.ai on instinct. It sat dormant for nearly a year. Then on March 2, 2026, Alibaba released Qwen3.5. The next day, his OpenClaw assistant Dao spotted that mlx-swift had been updated overnight with Qwen3.5 support — before the community had caught up. Dao quantized the model to 4-bit MLX format, uploaded it to HuggingFace, and wired it into a SwiftUI app running natively on iPhone. All in under 24 hours. That's not a story about technology. That's a story about what happens when the right tools meet the right vision. The creator of BECoach.ai is Tony Zhang — a father, author, and practitioner of the Transformation Economy (inspired by Joe Pine's new book in 2026). Tony's own chapter "Learn Differently" appears in Strategic Conversations (2025), the Amazon bestseller curated by Chris Voss, author of Never Split the Difference — selected from professionals worldwide. https://amzn.to/4s7BhLx What makes BECoach.ai different Every AI assistant you've used lives in the cloud. Your conversations travel to servers, get processed, get stored. Someone, somewhere, has access to what you said. BECoach.ai runs on your iPhone. The model lives on your device. Your conversations never leave. Not because we say so — because they physically can't. This isn't a privacy feature. It's the architecture. Powered by Apple MLX — Built for Apple Silicon Most AI apps run on servers. BECoach.ai runs on the chip in your pocket. Apple MLX is Apple's own machine learning framework — purpose-built for Apple Silicon. The same architecture that makes M-series Macs the fastest computers in the world powers every response in BECoach.ai. On iPhone 15 Pro and newer, the Neural Engine runs Qwen3.5 at full speed — no compromise, no throttling, no waiting on a server. • Fully offline after first launch • No account required • No subscription • No data collection • Works on a plane, in a basement, anywhere For coaches. For leaders. For anyone building something. BECoach.ai isn't just an AI chatbot. It's a thinking partner for people who are building — teams, businesses, communities, themselves. Ask it hard questions. Use it to pressure-test ideas. Let it push back. Export your conversations and turn insights into action. The best coaches don't give answers. They ask better questions. So does BECoach.ai. Your data. Your device. Your coach.
