Your running. Your assistant. Hare is a free running companion that connects your training to the assistant you choose. Sync Apple Health, keep your workouts and plans together, and bring your own assistant through MCP. KEEP YOUR TRAINING TOGETHER See workout history, splits, interval reps, readiness signals and training load. Follow saved sessions and send supported structured workouts to Apple Watch. ONE PLACE FOR MEMORY Find saved facts, preferences, training notes and decisions together in Settings → Coach → Memory, grouped by topic. Talk through changes with your connected assistant and let it save the details to Hare. BRING YOUR OWN ASSISTANT Add https://hare.coach/mcp to an assistant that supports remote MCP and sign in with the same Apple account. Talk through your training in that assistant's app. Your assistant can read Hare's running playbook, inspect data freshness and check schedules against training guardrails. KEEP THE PLAN CLOSE Your assistant can save sessions, run reviews, race plans and coaching notes to Hare. Plan changes refresh automatically when you return to Hare or reconnect. Find goals in Settings and read saved reviews with each workout. FREE FOR EVERYONE Hare has no subscription or paywall. Your assistant's subscription or API fees are separate, and remote MCP support varies by provider and plan. You can use Health sync, check-ins, workout history and existing plans without an assistant. YOUR DATA, YOUR CHOICE Choose what to sync from Apple Health and which assistants to connect. Manage or revoke assistant connections in Settings. Your chosen assistant's privacy terms apply to data you share with it. Existing Hare accounts, workouts, plans and saved memories are preserved. Hare provides training information, not medical advice. Its playbook and guardrails help inform coaching conversations; they do not guarantee an assistant's advice.

Verdict
The clearest difference is in-app purchases: Concrete Gym at none against Hare's 2. Concrete Gym also leads on iOS requirement (15.1 vs 17.0). Hare's advantage is update cadence (every 2 days vs every 3 months). On price, ads and device support there is nothing between them.
