You know what you need to do. You just can't start. EarlyBird drops you into a live focus room where other people are already working, so you start too — that's body doubling. Studying, a work deadline or a thesis: same room, same effect. EarlyBird is a body doubling app: you join a live focus session and work alongside other people — friends or strangers — until the thing actually gets done. It's the reason libraries work. WHY BODY DOUBLING WORKS Starting is the hard part, not the work. When someone else is visibly working, your brain stops negotiating and begins. That's body doubling, and it's one of the oldest ADHD tricks there is. • Join a live room any time and you're no longer working alone • See who's online and what they're working on • No small talk required — everyone is there to work AN ACCOUNTABILITY PARTNER ON DEMAND • Say what you're going to do before the session starts • Check in when the timer ends • Photo evidence at the end keeps you honest • Gentle nudges if you drift, not guilt A FOCUS TIMER THAT FITS YOU • Classic Pomodoro, or your own work and break lengths • Tag sessions by subject, client or project • See time logged today, this week and this month • Streaks and small wins instead of a scolding BLOCK THE APPS THAT STEAL YOUR SESSION • Pick which apps get blocked while you focus • Stop opening social media on autopilot • Take breaks on purpose, not by reflex • Your phone stops running the session BUILT FOR BRAINS THAT STRUGGLE TO START EarlyBird is ADHD-friendly by design: short clear sessions, a visible finish line, and other people in the room. Whether you have a diagnosis or just lose hours to your phone, it gives you structure without nagging. WHO IT'S FOR • Students who need a study room, not another to-do list • Anyone with ADHD looking for body doubling and real accountability • Remote workers and freelancers who miss having people around • Writers grinding through a thesis, dissertation or first draft • Anyone who has ever said "I'll start in five minutes" Free to download. EarlyBird Premium unlocks unlimited sessions and full stats for $2.99/week or $3.99/month.

Campfire OS — A sanctuary for deep work. Turn focus into a fire you tend. Start a session, set your phone face-down, and your campfire climbs higher and brighter with every minute of deep work. Pick your phone up mid-session and a storm rolls in — flip it back face-down within 20 seconds to save the camp. It's focus you can feel: a calm, beautiful ritual that rewards you for staying off the screen, instead of nagging you when you don't. THE RITUAL • Set your focus time and tap Start. • Place your phone face-down — the fire only grows while the screen rests. • Stay the course, and your streak climbs, night after night. SHIELD DISTRACTIONS Choose the apps and categories that break your focus, and Campfire shields them for the length of your session using Apple's Screen Time. No willpower required — the distractions simply aren't there. FIVE SIGNATURE ATMOSPHERES Set the mood for deep work with hand-crafted scenes, each with its own immersive ambience: • Alps — a clear night above the treeline • Cyberpunk — neon haze over a rooftop brazier • Rainforest — a warm hearth in the fog • Arctic — aurora drifting over blue snow • Desert — a canyon of stars over red rock BUILD A STREAK WORTH PROTECTING Every camp you keep builds a streak, with your sessions and stats stored privately on your device — and synced across your devices with iCloud. PRIVATE BY DESIGN No account. No advertising. Nothing to track. Motion and Screen Time data are processed only on your device, and your data never leaves your phone unless you turn on iCloud sync. Tend the fire. Guard your focus. The deep work is yours to keep. Terms of Use: https://vivaapps.co/campfire-os-app/terms Privacy Policy: https://vivaapps.co/campfire-os-app/privacy
