Comparison
TimerDuel vs Forest: which focus timer should you use?
Forest grows you a virtual tree if you don't touch your phone. TimerDuel runs a chess-clock that pits focus against breaks so you see your real focus rate. Two different philosophies — here's which one fits you.

Pick Forest if…
- • You study primarily on your phone and need it locked.
- • Cute visual rewards genuinely motivate you.
- • You're fine paying upfront and don't mind app installs.
Pick TimerDuel if…
- • You study on a laptop and want a measurable focus metric.
- • You're tired of rigid Pomodoro blocks that interrupt flow.
- • You want to know if you actually focused for 2 hours, or just thought you did.
- • You don't want another app, signup, or paywall.
The core philosophical difference
Forest punishes you for losing focus — your tree dies. That works until you stop caring about the tree. TimerDuel doesn't punish you; it just keeps an honest scoreboard. When you tap break, nothing dies. But at the end of the session, your focus rate is what it is. That gentle honesty turns out to be more durable than guilt-based gamification.

Which is better for studying, Forest or TimerDuel?
Forest is great if gamification motivates you and you study on your phone. TimerDuel is better if you study on a laptop and want a real focus-rate metric — not just a tree that dies when you check Instagram.

Yes. TimerDuel works in any mobile browser. For best results, study on your laptop and keep your phone face-down in another room — phone presence reduces cognitive capacity (Ward et al., 2017).
