Second Sun

Read full description

Second Sun was built by a stroke survivor, for survivors. At 22, Shawn Springs had a stroke. After 7 months of therapy, he rebuilt his life — but he did it without the tools, community, or companion he needed. Second Sun is the app he wished had existed. YOUR RECOVERY COMPANION Meet Sol — an AI companion built specifically for stroke and brain injury recovery. Sol isn't a generic chatbot. She knows your story, understands your journey, and shows up for you every single time. • Free: 10 Sol conversations per day • Plus: Unlimited conversations + Sol remembers your history across every session DAILY CHECK-IN Start every day with a simple mood check-in. Track how you feel over time and watch your recovery story unfold — one day at a time. MILESTONES Your wins deserve to be celebrated. Earn badges for 7-day streaks, 30 days, 90 days, and more. Every step counts and Second Sun sees it. CHAIR YOGA Adaptive yoga sessions designed for stroke survivors — led by Shawn himself, a certified yoga instructor and 12-year survivor. SECOND SUN PLUS Unlock your full recovery toolkit: • Unlimited Sol conversations • Sol remembers your conversations across sessions • Daily Recovery Journal — write, reflect, and grow • Goal tracking — set and celebrate recovery milestones • Curated Resource Library — vetted tools for survivors and caregivers CAREGIVER SUPPORT When stroke happens, it happens to the whole family. Caregivers get their own dedicated account — with Sol support, a personal journal, and resources made for them. Because you cannot pour from an empty cup. RESILIENT MINDS COMMUNITY Join our weekly virtual support group — Thursdays at 6:30 PM Central live on YouTube. Real people. Real stories. Real support. BUILT ON LIVED EXPERIENCE Second Sun was created by someone who has lived every hard day of stroke recovery. This isn't a wellness app repurposed for survivors — it was built from the ground up, for this community, by one of your own. You are not alone in this. Your second sun is rising. Second Sun Plus is available as a monthly subscription ($9.99/month). Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. Manage or cancel your subscription in your Apple ID Account Settings.
