ChkM8 – The Future of Safe Connections NEW UPDATE: ChkM8 has a bold new look and smoother app experience — making it easier than ever to meet confidently, safely, and authentically. In today’s world, most connections start online — but how do you really know who’s behind the screen? That’s where ChkM8 changes the game. ChkM8 is a portable reputation app that helps you make safer, smarter connections. Through anonymous, mutual ratings, users can evaluate one another in three key areas: Integrity – Are they honest and respectful? Likeability – Were they enjoyable to be around? Safety – Did you feel comfortable meeting them? Each rating is private by default, but users can choose to share their composite scores to show who they really are — a simple, credible way to stand out in a crowd of profiles. How It Works Consensual Ratings: Both users agree to rate one another after a meetup. Flexible Options: Use “Rate Now” right after a connection or schedule a rating within 24 hours. Anonymous by Design: No chat, no DMs — just verified behavior. Transparency: You can view how others have rated the people you meet, without ever revealing your own identity. ChkM8 helps you feel secure — not because someone else says they’re trustworthy, but because you’ve seen how they’ve behaved with others. Whether you’re meeting a date, a marketplace contact, or anyone new, ChkM8 turns reputation into real-world safety. Meet confidently. Rate honestly. Live safely.

Sidekick is the AI accountability coach for people who set serious goals and need someone to hold them to it. Pick a coaching persona. Set a goal. Get checked on every day. Sidekick is not a streak tracker with cute graphics. It is the voice that shows up when motivation doesn't, and asks the question you were hoping to avoid. WHAT MAKES SIDEKICK DIFFERENT Most habit apps reward you for opening the app. Sidekick rewards you for doing the work. Daily check-ins are conversational, not boxes you tap. Your coach remembers what you said yesterday, calls you out when you contradict it today, and keeps a private log of what you actually did versus what you said you would. FOUR COACHING PERSONAS The Operator: The leader. Plans before motivation. Believes ownership and preparation beat inspiration every time. The Engine: The relentless one. Keeps moving when everyone else stops. Does not negotiate with the part of you that wants out. The Architect: The thinker. Treats your life like a structural problem. Wants you to understand why before how. The Mentor: The patient one. Believes capability is built, not given. Will not let you call yourself broken. Each coach is an AI persona, inspired by themes from military leadership, mental toughness, clinical psychology, and growth research. None of them are real people. All of them are designed to make the right action the obvious action. HOW IT WORKS 1. Tell Sidekick what you actually want. Not what sounds good. Specific. 2. Choose your check-in cadence. Daily, twice daily, or only when you're about to skip. 3. Get the message. Answer honestly. Keep going. WHO IT'S FOR Founders. Operators. Athletes between seasons. People in life transitions. Anyone who already knows what to do and is not doing it. If you want an app that tells you you're doing great, this is the wrong app. PRIVACY Your goals and check-in data stay private. We do not sell or share your data. See the developer's privacy policy for details. Terms of Use (EULA): https://getgrowthmagic.co/terms Privacy Policy: https://getgrowthmagic.co/privacy PREMIUM Free tier: one coach, one goal, daily check-in. Premium: all four coaches, unlimited goals, custom cadence, voice-mode coaching, shareable accountability cards. Cancel any time.
