Tired of rigid 25-minute timers jarring you out of deep focus right when you're in the zone?

Meet FlowGuard — the adaptive focus and productivity timer built on Proportional Earned Rest (PER). Instead of forcing abrupt breaks, FlowGuard honors your natural flow state while ensuring you rest proportionally to prevent burnout.

🌟 WHY FLOWGUARD IS DIFFERENT
━━━━━━━━━━━━━━━━━━━━━

Traditional timers treat every session like a rigid box. When your alarm rings, you are forced to stop — breaking your train of thought.

FlowGuard flips the model:
• Baseline Focus Target: Start with a custom baseline (e.g., 25 minutes).
• Seamless Extended Flow: When you reach your target, a soft harmonic chime lets you know you’ve met your goal without interrupting your workflow. Keep focusing as long as your momentum lasts.
• Proportional Earned Rest (PER): Every extra minute of focus automatically calculates and banks proportional rest time (e.g., 1 min rest per 5 mins focused). The deeper you focus, the more rest you earn.
• Grace Buffer Protection: Need a quick pause? The smart Grace Buffer gives you a customizable safety window to step away and return without ruining your session streak.
