Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Merlin Bird ID

  • It only identifies birds, so it is not useful for plants, insects or other wildlife the way a general nature app is.
  • Sound ID can struggle in noisy environments or with overlapping bird calls, since it depends on a clean audio signal.
  • Being a free institutional project, feature releases and interface polish move more slowly than a funded commercial app.
  • Photo ID accuracy drops for juvenile birds, moulting birds or poor-quality photos, more so than for well-lit adult specimens.
  • It has no social or gamified layer, so users who want streaks, badges or a community feed will find it plain by comparison.

Roku

  • Roku takes a 20 percent cut of all revenue channel publishers receive through Roku Pay (purchases, subscriptions, ads), paying out the remaining 80 percent no later than 60 days after the end of the month the payment was received, with non-US partners restricted to PayPal or wire transfer (ACH/direct deposit is US-only) and bank fees applying to wire and ACH payouts (archived developer documentation, 2 May 2021)
