Duolingo's paid experience includes the notion of a "streak freeze". Every consecutive day that you complete a lesson, your daily streak increments. When you miss a day, you can use a freeze to retain the streak by practicing the following day.
A purist would argue that the streak has been broken. Is the freeze good?
I believe the freeze is good. We can arrive at that conclusion by working through our goals:
You remember all the days you spent maintaining the streak, not the day or two you failed to perform. You yearn to reach the 1 year streak mark. You persevere for longer than you imagined you'd go at the start, thereby practicing (the actual point of all this) more than you otherwise would have, in part because you were allowed to regard your streak as continuous.
You are, after 1 year, now considering going for 2 years. Would you have been more or less likely to follow that pattern of behavior if Duolingo forced you to think of the prior year as a 124 day streak, broken, followed by a 241 day streak? I suggest you'd be less likely to continue exhibiting the behavior.
None of this means that you couldn't be a purist about the streak. Indeed, some people will be more motivated by the dire stakes of a proper streak.
Rather, when something is this low stakes, indeed irrelevant to the goal of learning Spanish, it is malpractice to leave this free psychological boost of a resilient streak on the table.
Anyway, today is the 26th. I neglected to post yesterday on the 25th. I regard my 2025 blogging streak as intact.
(My Duolingo "streak" is at 37 days. I completed 1 year in May and mostly paused since then. Interestingly, Duo doesn't show me "my best streak" anywhere... Perhaps they want your current streak to always be your longest!)
