Stop scrolling. Start living. One Thing flips phone addiction on its head. Instead of fighting dopamine-driven habits, this app channels them — blocking distractions until you complete one meaningful activity each day. Exercise, read, meditate, do deep work, or practice an instrument. Finish first, then earn back access. The result? A daily digital detox that builds real habits, reduces mindless scrolling, and gives you hours of focus back. SUBSCRIPTION INFORMATION All features require an active subscription after the free trial period. HOW IT WORKS (Subscription Required) Pick one activity every morning: gym, reading, meditation, studying, journaling, running, walking, or any productive pursuit. Until it's done, distracting apps stay locked. No willpower needed. The environment does the work. SMART BLOCKING (Subscription Required) System-Level Control: Native iOS Screen Time integration locks apps at the deepest level Personalized Filters: Select exactly which apps to restrict based on individual triggers Flexible Scheduling: Set weekly routines, daily challenges, or immediate timed blocks Usage Caps: Limit daily or weekly opens and minutes for specific apps Emergency Unlock: Safety valve for moments when access is genuinely urgent AI-POWERED VERIFICATION (Subscription Required) Photo Proof: Snap a picture and GPT-4 Vision confirms whether the activity was actually completed Works Everywhere: From gym selfies to reading sessions, the AI adapts to any habit No Cheating: Intelligent analysis catches shortcuts and keeps accountability honest TRUE FOCUS MODE (Subscription Required) Distraction-Free Timer: Full-screen countdown for deep work, studying, or creative sessions Cross-Device Sync: Pairs with Mac for seamless focus across phone and desktop ADHD-Friendly: Structured sessions with grace periods reduce the friction of getting started PROGRESS & MOTIVATION (Subscription Required) Streak Tracking: Build momentum day after day with visual completion calendars 18-Level Progression: Journey from "Brain Rewiring" on Day 1 to "One Year Champion" Detailed Analytics: Monitor hours saved, daily completion rates, and long-term growth Milestone Alerts: Celebrate achievements at key moments throughout the journey PRIVACY & RELIABILITY (Subscription Required) On-Device Data: Personal information never leaves the phone Background Processing: Blocks stay active even when the app is closed Live Activity Widget: Persistent lock-screen reminder showing streaks and countdowns BUILT FOR Anyone trapped in a scroll-refresh-repeat cycle Students needing structured study sessions and fewer distractions Professionals seeking a digital detox during work hours Fitness-focused individuals building consistent gym or running routines People with ADHD looking for external structure and accountability Families creating healthier relationships with technology WHY IT WORKS Traditional habit trackers send reminders and hope for the best. One Thing creates real consequences: access to social media, news, and entertainment stays blocked until the daily habit is done. It's not about restricting freedom. It's about trading a dopamine loop for a life-changing routine. JOMO (joy of missing out) replaces FOMO, one day at a time.

PostMortem – Your Digital Legacy Companion Keep the important stuff safe, organized, and delivered when it matters. PostMortem lets you store messages, passwords, contacts, debts, and files, then securely release them to trusted recipients after a period of inactivity. What it does - Secure “message boxes” for your wishes, instructions, passwords, debts, and documents. - Time-locked delivery: set an inactivity window; if you don’t check in, your boxes release. - Recipient portal: loved ones get a clean, guided view of everything they need. - Attach files: upload photos, PDFs, and more; recipients can view or download. - One-tap PDF export: generate a polished summary of a box to share or archive. - “I’m alive” check-in: send heartbeats to keep boxes locked until you’re ready. - Contact book: manage who receives what, with multiple recipients per box. - Works offline-friendly: view and organize even with spotty connectivity; sends when back online. How it works 1. Create a box for a person or scenario (estate plan, account list, instructions). 2. Add text notes, login credentials, debts/obligations, and file attachments. 3. Set the inactivity timer that should trigger release. 4. Invite recipients—only they can access their assigned boxes after release. 5. Periodically check in with “I’m alive” to keep things locked; if you stop, PostMortem delivers. Security you can trust - End-to-end mindset: data is encrypted before it’s sent and decrypted only for recipients. - No shared passwords: each box uses keys you control. - Privacy by default: nothing is sold or shared; you decide who sees what and when. Great for - Estate planning and last wishes - Household logins and subscriptions - Financial obligations (who owes what, due dates, contacts) - Family instructions, medical notes, insurance details - Secure document handoff (IDs, policies, deeds, checklists) Why you’ll love it - Clear, modern design that keeps complex info tidy. - Rich attachments and PDF exports for a complete record. - Peace of mind: your people get exactly what they need, precisely when they need it. Get organized today so your loved ones aren’t left guessing tomorrow. Install PostMortem and set up your first box in minutes.
