Cited: What RevenueCat measures across subscription apps

Their report has no category matching Invoicing apps apps, so only all-category figures are shown. A near-match would be a guess.

  • the median app barely grows; the tails are extreme

    median MRR +5.3% YoY · top decile +306% · bottom decile contracting

  • the launch flood vs the incumbency moat

    ~2,000 → 14,700+ new subscription apps per month (Jan 2022 → Jan 2026), yet pre-2020 apps still hold 69% of subscription revenue

  • even top categories take over 100 days to reach $10k revenue

    >100 days to the first $10k

RevenueCat, State of Subscription Apps 2026, 115,000+ apps · $16B+ tracked revenue · >1B transactions. Published industry figures, shown for context; App Imp’s own numbers are counted from reviews and never mixed with these.

How this is counted

We count the reviews we hold again every week. Nothing is guessed. A topic is found by the words a review uses, so the same review always lands in the same place. Every star counts. A share is the part of all reviews here that mention a topic. We compare it with the same share across 794 Business apps, the group most of these apps are in. A topic is a gap when at least 20 reviews mention it, at least half the apps have it, and it comes up at least 1.15 times as often as usual. A problem in one app is that app’s bug. A problem in every app is nobody’s gap. This market has no full report yet, so the per-app notes are absent rather than estimated.
