Frequently asked questions
What is a focus timer?
A focus timer is a simple countdown built to protect a planned work block from distractions and clock-checking.
Should I use 50/10 or 25/5?
Use 25/5 when starting feels hard. Use 50/10 when the work is deep and you can stay engaged for longer.
Can this help with studying?
Yes. Use one focus block for a specific chapter, problem set, or review task, then take a real reset break.
How is a focus timer different from a stopwatch?
A stopwatch measures how long you worked after the fact. A focus timer defines the commitment in advance, reducing clock-checking and giving the session a clear endpoint.
