Focus Study Timer - BoostSkill

About

BoostSkill is an offline-first Android app built around the 100-Hour Rule—the principle that 100 hours of deliberate practice puts you ahead of 95% of people in any discipline.Unlike bloated subscription apps, BoostSkill is completely private and friction-free:• 100-Hour Skill Roadmaps: Break big learning goals into clear milestone gates.• Gamified Mascots: Unlock companions that level up with your focus sessions.• Flexible Timers: Pomodoro, countdown, and stopwatch modes with Android widgets.• Deep Analytics: GitHub-style 365-day heatmaps and Focus Bio-Rhythms.

offline-first is cool, but how's the data storage work? 100 hours sounds great, but what about tracking accuracy?

100 hours of practice sounds cool, but how does it actually track progress offline? kinda skeptical about that.

offline focus timers are a nice niche, but how does this compare to existing apps in terms of features?

the timer design is nice, but it could use clearer labels for the features.
