A wee plan, based on research

Breaks can help cut doon weariness, but their effects on performance depend on the task and context. Choose a block lang eneuch tae dae somethin meaninfu. Use the task field tae name whit ye'll practise, sic as workin oot twa problems fae memory.
There's nae scientifically optimal work-to-break ratio here. The preset lengths are handy options. Ye can shorten a block, tak a break sooner, or finish the problem ye're workin on.
A few handy answers
Whit gin A want tae finish a problem first?
Use the finish-this-problem option tae keep the current timer gaun. Stoppin time stays in sicht. Extendin a block micht leave less time for whit comes efter; edit the rest o the plan gin need be.
Will the timer work offline?
Ance the tool has loaded, its timer works wi nae connection while the tab is open. It uses elapsed time insteid o coontin timer ticks. The browser bein suspended can delay the on-screen update, and closein the tab stops the timer.
Can A juist coont up?
Aye. Choose count up and stert wi ae task. There's nae streaks, scores or sounds ye maun hae.
