Most focus timers only track isolated minutes or hide basic insights behind expensive monthly subscriptions. BoostSkill is an offline-first Android app built around the 100-Hour Rule—the proven principle that 100 hours of deliberate practice puts you ahead of 95% of people in any skill.
Features:
• 100-Hour milestone roadmaps
• Evolving mascots that level up with focus
• Pomodoro & Android home screen widgets
• Focus Bio-Rhythms & 365-day heatmaps
