iPhone
In the darkness, a gentle glow waits for you.
Firefly is not another productivity timer. It's a quiet companion for your focused hours. Tap the screen, and fireflies drift into your night — soft, warm, alive. They stay as long as you do.
THE FIREFLIES REMEMBER
Start a session with a single tap. Fireflies appear and slowly multiply, drawn to your calm focus. No countdowns staring you down. No streaks punishing you for stopping. Just light, floating in the dark.
If you need to step away, that's okay. They'll probably still be here when you come back.
CONSTELLATIONS IN THE NIGHT
Focus long enough and something quiet happens — your fireflies spontaneously gather into real constellation formations. You don't summon them. You don't choose them. You just look up, and they're there.
Every constellation in the night sky is here, each with a hand-drawn illustration. Some appear often. Some are rare. Some you may never see. That's part of the beauty.
A JOURNAL OF ENCOUNTERS
Every session is an encounter, not an achievement. Your Firefly Journal records each quiet moment — not as trophies, but as memories of time spent together.
Seasons change. The fireflies change with them — their color shifts slowly, spring to summer, autumn to winter, without you even noticing.
DESIGNED FOR THE NIGHT
• Dark-only interface — a darkness that feels alive
• Firefly colors that follow the seasons
• Ambient soundscapes: crickets, rain, waves, streams
• A gentle haptic farewell when each session ends
• Home Screen, Lock Screen, and Dynamic Island widgets
• One-tap focus, from a brief moment to a whole night
• Leave briefly and come back — they'll still be here
• iCloud sync across your devices
• No account. No ads. No tracking. Your data stays on your device.
