You are not overreacting. You are not too sensitive. Your nervous system just feels things more intensely than most. Felt is built for adults with Rejection Sensitive Dysphoria β€” the intense emotional pain triggered by perceived criticism, rejection, or failure that is common in ADHD and autism. If you have ever been blindsided by overwhelming emotional pain from a comment, a silence, or a look β€” and spent hours recovering β€” this app was built for you. NOT A DIAGNOSTIC TOOL Felt uses self-reflection tools and AI-powered pattern analysis to help you understand your RSD experience. It is not a clinical assessment and does not replace evaluation by a qualified mental health professional. WHAT IS RSD? Rejection Sensitive Dysphoria causes sudden, overwhelming emotional pain from perceived or actual rejection, criticism, teasing, or failure. It is widely recognized in the ADHD and autism clinical community and affects millions of adults who have never had a name for why they feel things so intensely. RSD SCREENER Ten reflection questions based on the clinical work of Dr. William Dodson and CHADD. One free AI interpretation helps you understand what your responses suggest about your experience. EPISODE LOGGER When an episode hits, log it quickly. Trigger type, intensity, physical symptoms, duration, and recovery notes. Building a record is the first step to understanding your patterns. IN-THE-MOMENT TOOLKIT β€” ALWAYS FREE When an episode is happening right now: - Immediate validation: "You are not overreacting. This is RSD." - Guided breathing and grounding exercises - Affirmation cycle: "This feeling has a name. It will pass." - Episode peak timer β€” most RSD episodes peak within 3 minutes - Crisis resources including 988 and Crisis Text Line β€” always free, never paywalled PATTERN DASHBOARD (Pro) Visual analytics across your logged episodes. Most common triggers, intensity over time, time-of-day patterns, recovery trends, weekly frequency chart. See your RSD clearly instead of just living inside it. AI WEEKLY INSIGHTS (Pro) Claude AI reviews your last 7 days and surfaces patterns in warm plain language β€” which environments trigger your most intense episodes, what your recovery trend looks like, and personalized coping suggestions based on your actual data. COPING STRATEGY LIBRARY (Pro) Evidence-based strategies by category: in-the-moment, prevention, communication, workplace, relationships, self-compassion. AI personalizes recommendations based on your trigger patterns. Save what works. COMMUNICATION SCRIPTS (Pro) Pre-written scripts for the hardest RSD conversations. Explaining RSD to a partner. Asking for feedback safely. Responding to criticism at work. Claude AI generates custom scripts for your specific situation. TRUSTED PERSON MODE (Pro) Share a read-only summary of your patterns with someone you trust β€” on your terms, only what you choose. Help the people who care about you understand without having to explain in the moment. INSIGHTS JOURNAL (Pro) Daily RSD-specific reflection prompts, free text journaling, weekly AI theme analysis, and PDF export for your therapist. YOUR DATA Stored securely via Firebase. Optional cloud sync. No ads. No data selling. Ever. Felt is built with genuine understanding of what RSD feels like from the inside. You are not broken. You are not too much. You just need better tools. Not a clinical diagnosis. For self-reflection only. If you are in crisis please contact 988 or a qualified professional.

Twins. Triplets. More kids than hands. NapSip is the only tracking app built from the ground up for multiples β€” not retrofitted. Both parents see in real time who's sleeping, when the last feed was, and how much β€” on every device, no detours. WHAT YOU TRACK β€’ Sleep β€” start/stop with a live timer. See at a glance who's asleep and for how long. β€’ Feeding β€” bottle (ml slider) or breast (left/right with duration). Fast, even half-asleep. β€’ Diapers β€” wet, dirty, or both, logged in seconds. β€’ Solids β€” gram slider for purees and first meals, optional toggle. β€’ Growth β€” weight and height over time, shown as a curve. β€’ Handoff notes β€” quick notes for shift changes between parents. FOR BOTH PARENTS Create a family and share the invite code with your partner. From that moment on, you're in sync β€” what one logs, the other sees within a second. No chaos. No duplicates. No "did you already feed them?" (Due to platform limits, live sync doesn't reach the widgets instantly.) SLEEP PREDICTION NapSip learns your children's sleep patterns and shows when the next nap is likely coming β€” based on real data from the last 14 days, adjusted for age. Still: there's no point in forcing yourselves to follow a recommendation. Your child's real sleep cues always come first β€” the prediction is a hint, not a plan. HISTORY & INSIGHTS β€’ Day timeline: sleep and feed blocks as a visual 24-hour view β€” per child. β€’ Week view: compare sleep duration, feed amounts, and diaper counts over 7 days. β€’ At the pediatrician: real numbers, not estimates. WIDGET & NOTIFICATIONS Current status right on the Home Screen and Lock Screen β€” without opening the app. Start or stop sleep directly from the widget. Notification when a child sleeps unusually long. PRICING NapSip is free to download. Creating a family costs a one-time €14.99 β€” no subscription, no hidden costs. The partner joins for free with the invite code. PRIVACY Your data is yours. No ads. No tracking. No sharing with third parties. All data is encrypted in transit and at rest. Fully GDPR-compliant. Built by parents of multiples β€” for parents of multiples. With love from our kids Maja, Cleo, and Nova.
