Two specific frictions send people looking for something else: ads on the free tier, and being asked to speak into a microphone. Here's how Duolingo actually handles both, and what a different approach looks like.
Duolingo's free tier is genuinely usable — it covers all 40+ of its languages at no cost — but it's ad-supported. Ads show up between lessons, and the free tier also limits daily practice with a "hearts" (lives) system, so getting several answers wrong in a row can mean waiting or paying to keep going. To remove ads entirely and get unlimited hearts, the path is Super Duolingo, priced around $12.99/month or about $95.99/year (roughly $8/month on the annual plan). That's the tradeoff on the table: free-with-ads-and-limits, or paid-and-unrestricted.
Separately from ads, Duolingo's courses include microphone-based speaking exercises as a core, well-known part of the product — this is the pronunciation-scoring technology it's known for. It's not every single exercise in every course, but it's woven throughout as a defining feature, not an optional add-on you can permanently switch off within a course. For learners who want that speaking practice, it's a genuine strength. For learners who are self-conscious speaking aloud, don't have a private space to do so, or simply don't want to rely on a microphone at all, it's a recurring friction point that upgrading to Super doesn't remove — Super removes ads and the hearts cap, not the speaking exercises.

If ads are the only friction, Super Duolingo solves that cleanly for about $8-13/month, and you keep access to 40+ languages plus speaking exercises if you want them. If avoiding a microphone entirely is the actual goal — not just avoiding ads — upgrading tiers on Duolingo doesn't change that, since speaking exercises are part of the base course design, not a paid extra. That's the gap Lumi Lingo is built to fill: no ads on any plan (including the trial), and every single exercise across Spanish, French, and ASL is answered by tapping or typing, with the correct-answer choices read aloud instead of requiring the learner to speak. The tradeoff, again honestly: 3 languages instead of 40+, and no ongoing free tier — just a 72-hour trial before the $11.99/month subscription starts. For someone whose main complaint about Duolingo's free tier is specifically ads, or whose main complaint is specifically the microphone, it's worth being clear on which one you're solving for, since the two apps solve them differently.
