The most persistent question in anyone's day is not about work or money. It is quieter than that: what should I eat? Piero Linares and Ulises Olaves, childhood friends from Lima, decided in 2019 that a question asked that often deserved a better answer than guilt and guesswork. The result is Fitia, a nutrition app that now sits on more than 10 million phones and, in much of the Spanish-speaking world, outranks the American incumbents that were supposed to own this category.
Fitia does something deceptively plain. You tell it your goal - lose weight, build muscle, or hold steady - and it builds a daily eating plan around foods you actually like. You log what you eat by snapping a photo, saying it out loud, typing it, or scanning a barcode. The app counts the calories, tracks the macros and micronutrients, and quietly rewrites tomorrow's plan based on how today went. That is the whole trick, and it is harder than it sounds.
The Founders01Two engineers, no nutrition degree
Neither founder came from health or fitness. Linares is an industrial engineer who spent nearly four years in finance and business development at one of Peru's largest conglomerates. Olaves is a systems engineer who had worked as a product manager building software for financial institutions. In 2019 they both left stable jobs for an idea that started as a single algorithm: suggest a day's meals based on what someone was trying to accomplish.
That outsider angle turned out to be the point. They treated eating well as a data problem, not a willpower problem - a scheduling puzzle you could solve with software rather than a character flaw to overcome. It is the difference between an app that nags you and one that just hands you a plan.
The two are childhood friends, which matters more than it might seem. Consumer apps that ask people to change a daily behavior tend to die in the gap between intention and habit, and closing that gap requires a founding team that can argue about small decisions for years without breaking. Fitia's early product reflected a shared conviction rather than a committee: keep the interface simple, keep the plan flexible, and never make the user feel like they have failed a test. A plan you abandon after a week is worthless, no matter how scientifically correct it is.
Peru was an unlikely launchpad for a global health app, and that constraint shaped the product. There was no local playbook to copy and no deep-pocketed competitor to imitate, so the team built for the users in front of them - people who wanted to eat better without hiring a nutritionist or memorizing a spreadsheet. The features that survived were the ones real users kept opening, which is a more honest filter than a roadmap drawn up in a boardroom.

02Remove every excuse not to log
Anyone who has tried to track their food knows the failure mode: you skip one meal, then two, then you stop opening the app. Fitia's answer is to make logging almost frictionless. Photo, voice, text, barcode, or manual search - five doors into the same room. Behind them sits a database of nearly two million foods, filterable by country, with entries reviewed by nutritionists rather than crowd-typed by strangers. In a market full of AI shortcuts, that unglamorous accuracy is a real moat.
On top of tracking, Fitia layers the features that turn a logger into a daily habit: personalized meal plans, smart grocery lists that build themselves from your plan, Instacart ordering, family meal planning for a whole household, and a 24/7 AI nutrition coach that answers questions and adjusts your guidance in real time.
The personalization is the quiet differentiator. Most trackers treat you as a calorie budget and leave the rest to your discipline. Fitia starts from the food you already like and builds the math around it, adjusting portions and swaps so the target is met without the plan feeling like punishment. Users can steer it toward weight loss, muscle gain, or body recomposition, and the plan shifts as the numbers on the scale and the tape measure change. The app also tracks weight, body measurements, fat percentage, and progress photos, and connects to Apple Health and Health Connect so the data does not live on an island.
The grocery and family features push the app past the individual. A smart shopping list assembled from your week of meals is the kind of small convenience that quietly earns loyalty, and the Instacart tie-in shortens the distance between a plan and a full fridge. Family meal planning, meanwhile, aims at a real household problem: cooking one dinner that fits several people's goals. It is a bet that the most durable version of a nutrition app is not a personal tracker but a shared utility that a whole home comes to rely on.
03Winning the backyard first
The received wisdom said a consumer app out of Peru could not beat MyFitnessPal. Fitia did exactly that where it counts. Across Spain and core Latin American markets, it leads MyFitnessPal, Lose It, Cronometer, and MacroFactor in downloads and top-grossing performance, according to Sensor Tower data. It operates across fifteen Spanish-speaking countries, with Mexico, Spain, Chile, Colombia, Argentina, and Peru as its base.
Where Fitia sits against the incumbents
The strategy reads like a textbook, in hindsight: win where you are underestimated, then expand from strength. In 2024 Fitia turned toward the United States, opening an English-language push with influencer collaborations and social advertising rather than a giant marketing budget. It also added a Reddit-style community feed to deepen retention and position itself as a broader fitness hub rather than a solitary tracker.
There is a practical reason the LATAM lead matters beyond bragging rights. A regional food database is genuinely hard to build - the arroz con pollo a user logs in Lima is not the chicken-and-rice bowl a user logs in Austin, and the packaged goods on a shelf in Madrid differ from those in Mexico City. By covering nearly two million foods filterable by country and checking them with nutritionists, Fitia built accuracy where the American incumbents were thin. Getting the data right in markets others under-served is not glamorous work, but it is the sort that is expensive to copy.
Entering the US is a different fight. It is the most crowded market in the category, home to MyFitnessPal, Lose It, Cronometer, MacroFactor, Yazio, and Noom, and customer acquisition there is costly. Fitia's approach - influencers and organic social rather than a burn-the-cash launch - fits a company that has kept its spending disciplined from the start. Whether that is enough to repeat the LATAM result is the open question hanging over the next few years, and it is the one worth watching.

04$125K in, and no rush for more
Here is the part founders rarely brag about. Fitia was accepted into Y Combinator's Summer 2021 batch - rare for a Latin American consumer app - and raised a seed round of roughly $125K, with Goodwater Capital and HOF Capital among the backers. Then it did something unusual: it largely stopped there. Reported figures put Fitia at around $3.5M in revenue on a team of roughly two dozen people. Lean by design, not by accident.
The model is classic freemium: a large free base, a premium tier that unlocks the smart planning and AI coach, and a family plan aimed at the household. The economics work because the product earns its place in a daily routine, and daily routines are where subscription businesses live or die.
Staying lean was also a strategic choice about where the leverage sits. Rather than raise a large round and spend it acquiring users at a loss, Fitia leaned on word of mouth, app-store ranking, and a product good enough to keep people paying. That approach is slower and less headline-friendly, but it leaves the founders in control and the business answerable to customers rather than to the next fundraising milestone. For a category built on retention, that alignment is not a small thing.

06What Fitia actually proves
Strip away the metrics and Fitia is an argument about where good consumer software can come from. The company started in markets that Silicon Valley treated as an afterthought, built for the way its users actually eat, and let habit do the compounding. For anyone tempted to believe the big categories are already settled, Fitia is a useful counterexample: the incumbent's biggest weakness is often that it forgot who it was building for.
For a user, the pitch is simpler still. Open the app, log a meal in a second or two, and let the plan bend around your life instead of the other way around. That is a modest promise. Ten million people apparently find it worth keeping.
