Not really free: energy limits and paywalls
Energy System Makes App Unusable. I’ve used Duolingo for years, but I’m now considering deleting the app. A new energy system has been implemented that makes it so I can’t even do 2 full lessons a day…2★ · Sep 17, 2026

“I built ReviewMole because I wanted a quick way to read the reviews of big apps and spot opportunities. Plenty of famous apps have unhappy users, and every complaint they share is a gap a new app could fill. I didn't want a subscription just for that, and I wanted something my agents could use too.”
