Fourteen days before a flight to Mexico City is enough runway to get comfortable ordering food in Spanish. It is not enough runway to get fluent, and mixing those two goals up is the most common travel-prep mistake I see among people juggling a couple of language apps and a busy work calendar.
A disclosure before anything else: some of the language apps and services named below are ones I link to through referral programs, and if you subscribe after clicking, I earn a commission at no extra cost to you. I only write up apps I have actually paid for and used long enough to have a real opinion, including the ones I eventually let lapse because the interface annoyed me.
The Fourteen-Day Test
Two weeks is a strange window for language-app advice, because almost none of it gets written for someone working against a deadline. Most guides assume months of open-ended runway or an ongoing project with no real endpoint. What actually matters on a fourteen-day sprint is narrower: can you build one small daily habit that survives a packed freelance schedule, and can that habit carry you through the handful of real interactions a trip will throw at you, including ordering, asking for the check, understanding a price out loud. That's a different question from whether you can keep a streak counter alive; a real habit survives a missed day, while a streak just resets and quietly convinces you the whole thing failed.
Before any of the apps, I tried the analog version of this: a one-sentence-a-day journal in Italian, on paper, no app involved at all. It lasted three entries before I ran dry and gave up, which is roughly when I started trusting a phone notification more than my own discipline to keep a habit moving.
Rocket Languages Versus Mondly: The Habit-Building Trade-Off
My freelance clients sometimes build onboarding flows for English-teaching products, which is the only reason EF English Live was on my radar at all. It has a genuinely large structure, sixteen levels mapped to the CEFR, built for gauging conversation-readiness in a language a learner already half-knows, which suits a corporate consultant polishing English between calls far better than someone starting Spanish from zero. For my trip, it was a non-starter before I'd even opened the app.
Rocket Languages was the next stop, partly because a friend from a UX conference a few years back, Piotr Zamoyski, has been nudging me toward it by email for ages, he prefers slow, structured grammar study over anything that looks like a game, and Rocket Languages' audio-first course library is built exactly for people like him, the kind of lessons you can run through headphones on a walk without ever looking at a screen. It pairs that format with a serious money-back window, 60 days, generous by the standards of language-app subscriptions, and I'd already tested the model once, on trading my daily streak for a lifetime seat in their Italian course. Whether a one-time purchase like that beats a monthly app fee for a casual learner is its own separate argument, and it mostly comes down to how many languages you're actually serious about finishing rather than sampling.
Mondly answers a completely different question. It isn't built for someone reconnecting with a language spoken at home growing up, that's a specific situation with its own considerations I won't get into here, it's built to get you to say one Spanish sentence a day and make that feel automatic. Mondly by Pearson covers 41 languages, which is more relevant to my occasional Japanese daydreaming than to Spanish specifically, and it leans on phrase recall rather than teaching you to generate new sentences from grammar rules, useful for a two-week sprint, less useful the moment you want to construct something Rocket's grammar drills would have prepared you for.
Why the AR Mode Couldn't Hear Me
AR mode puts a virtual instructor in the room through the phone camera, then expects you to speak the response out loud for it to grade. In practice, Mondly's voice recognition is hit-or-miss: it can lock onto a single word and refuse to register it three times in a row, reading silence into an answer that was said perfectly clearly. Mine stalled on "la cuenta" more than once before I gave up and typed the response instead, which defeats the entire point of a spoken drill.
None of that ruins the habit itself, though. A clunky voice check is still faster than skipping the lesson outright, and skipping is the real risk on a two-week sprint, not an imperfect AR grade on a Tuesday.
Fitting Lessons Into an Actual Workday
Most language-learning advice assumes long blocks of uninterrupted time, which is not how a freelance schedule works. My real day is a series of four-minute gaps, such as waiting on a client's Figma comments, waiting for a Zoom room to open, and that's the shape a Daily Lesson is built for, not a sit-down study hour.
I ran most of these lessons at Cargo Coffee on Atwood Avenue, in the gap between ordering and actually opening the laptop, which turned out to be almost exactly the length of one lesson.
There's a specific tap-rhythm to running a vocabulary drill standing at a desk between calls, quicker and less even than the typing I do for client work, and it's oddly satisfying once the phrases start landing without translating them in my head first.
Rocket's audio has crept into the same slivers of time. I've caught myself answering a Rocket Languages prompt out loud while typing up a client invoice, not breaking stride enough to notice I'd switched contexts until the sentence was already out.
That's not spaced-repetition in the formal, deliberate sense, that system deserves its own explanation elsewhere, but the daily-lesson habit does something similar by accident, just by putting the same handful of phrases in front of me on a loop. Spanish, at least, uses the alphabet I already read every day for client work, which is a different problem entirely from the script-acquisition climb of something like Japanese kanji.
If you're juggling more than one language interest at once, I've written more about managing that particular mental load in my Mondly review for beginners.
A daily lesson that starts as a chore and turns into routine is really just a practical way of managing language learning anxiety without ever naming it that directly.
The Question a Vendor in Roma Norte Answered
The actual test wasn't inside any app. It happened at a chilaquiles stand in Roma Norte, ordering "chilaquiles verdes con huevo, sin cebolla" and having the vendor just nod, quote the price, and move on to the next customer without asking me to repeat anything.
That's a decent working definition of whether an app did its job for travel prep, not a score inside the platform, but whether a stranger in a real transaction understood you the first time and didn't slow down to accommodate you.
A reader named Anneliese Torrington asked, in a comment on an earlier post, whether two weeks is really enough time to prepare for a trip. The honest answer is that it depends entirely on what "prepared" needs to mean: survival Spanish at a food stall is a fourteen-day problem, and anything past that needs months of study, not an app sprint.
Whether it's worth keeping a subscription active afterward depends on how often the next trip is likely to happen. For me, with another one probably on the horizon and the Japanese daydream still nagging, keeping Mondly running costs less than the mental overhead of re-deciding from scratch every time a flight gets booked.
