Loved by early adopters.

Here's what our beta users are saying about Mellow.

S
S***sStudent

It finally clicked!

Okay so I've literally tried EVERY app. But Mellow's AI explained ser vs estar in Spanish and it just... made sense?? Like talking to a friend, not reading a textbook. Game changer.

D
D***nExpat in Tokyo

Survival mode unlocked

True story: the 'Ordering Street Food' deck saved me last night. Swiped through it on the train, walked up to a yatai 20 mins later, ordered yakitori like I knew what I was doing. Felt good.

E
E***zPolyglot

Beautiful and addictive

Most language apps are spreadsheets wearing a game costume. Mellow is different. The animations, the micro-interactions, the typography... someone actually cared about the craft here.

M
M***nBusiness Traveler

No more awkward silence

Look, networking events used to terrify me. The AI roleplay scenarios here are tough but they work. Practiced small talk until it stopped feeling like a performance. Worth every minute.

Y
Y***aLearner

Smart review system

The FSRS algorithm is legit. It knows exactly when I'm about to forget something and quizzes me right before. No wasted reps on words I already know. Efficiency matters to me.

J
J***nCasual Learner

Better than doomscrolling

Swapped my morning TikTok habit for Mellow's Discovery feed lol. Same swipe energy, except now I actually learn French slang instead of watching cats fall off tables.

Context is everything

As a language teacher, I notice things. This app teaches words in full sentences, not isolation. My students who use it? They sound natural. That's rare for an app.

A
A***mRemote Worker

Perfect for commute

Discovery cards are genius. Five minutes on the subway, swipe through some real phrases, done. No pressure, no streaks guilt-tripping me. Just... learning when I feel like it.

M
M***sBusy Mom

Finally something that fits

Between kids and work, I have maybe 10 mins a day. Installed the app on my phone, use it while waiting for pickup. Three months in and I can actually chat with my in-laws in Portuguese now.

T
T***nAnime Fan

Anime Japanese is real!

They have a whole course for anime Japanese lmaooo. Not gonna lie, learning casual speech from shows I actually watch hits different. Finally understand what characters are really saying.

L
L***kFrequent Traveler

Actually useful phrases

Other apps teach you 'The elephant is big'. Mellow taught me how to ask for no cilantro and complain about slow wifi. You know, things I actually need abroad.

R

The science is solid

Did my research on FSRS before trying this. The implementation is clean. Retention rates are noticeably better than Anki defaults. Plus the UX doesn't make me want to cry. Win-win.
