The effect of the holiday season on apps and products.

SwiftLee Weekly these days will be a little less filled with content as I can tell writers are taking a holiday break. Holiday seasons impact regular patterns, impacting both this newsletter and your apps.

I'm looking at my MRR multiple times daily (yes, I'm addicted!) since it's a great motivator. Same seasonal statistics appear and show lower usage compared to other weeks.

If you're looking at your statistics, it being a blog, app, or newsletter, do realize seasons might impact your regular numbers. If possible, it's best to compare your statistics to similar seasonality, like the same week a year ago. Another option would be to run the analysis over a more extended period.

Speaking of holidays: I've got two weeks before my holiday starts! But first: conference time. I'll be attending SwiftConf, and you can find me in Frankfurt this Friday. Hopefully, I'll see you there!

Enjoy this week's SwiftLee Weekly!
