Anyone prioritizing published price and feature breadth together. Stay Focused is cheaper than Fella on every listed plan while also including website blocking, profiles, and statistics Fella doesn't have.
People who want a shorter commitment than a full year. The quarterly plan is a middle option most competitors don't offer at all, useful if you want a discount without a twelve-month lock-in.
Less ideal if a single, unchanging exception is what you actually want. Stay Focused's profiles, allowlisting, and multiple modes mean more configuration than Fella's one fixed rule, which is a tradeoff of flexibility for simplicity, not price.
Worth considering if you've previously found subscription apps in this category expensive. At under $4 a month, Stay Focused sits closer to a casual utility purchase than a premium subscription, which may matter if cost has been the reason you've avoided a dedicated blocker until now.
