Stay focused, stay on track. ADHD Cricket gently chirps at regular intervals through your day — a small nudge to pause and ask: "Am I still on task?" If your attention tends to wander, those regular check-ins make a real difference. No nagging, no clutter — just a friendly cricket chirp to bring you back. How it works: • Set your active days and hours • Pick your interval (every 5 minutes to every 2 hours) • Choose your sound — cricket, bird, or sine — with pitch and volume to taste • Press Start and get on with your day Pro tip: keep a notepad handy. When you hear the chirp, jot down what you've been doing, then refocus. Runs quietly in the background — it chirps on schedule even when your phone is locked, and rests outside your chosen hours. Simple, calm, and built to fit around your life.
