“just eat more” is not advice.
you've heard it from trainers, friends, the internet, your mom.
it doesn't tell you what. when. or how much.
four years of trying. zero kg gained. you're not the problem.
03
the apps you tried were built for weight loss.
red bars when you go over. shame copy when you eat dessert.
one guy on reddit said myfitnesspal told him to eat NEGATIVE 700 calories to gain weight.
that's the kind of math you're trusting.
04
you don't know what “30g of protein” looks like.
nobody does. you're being told to track grams without anything to measure with.
klyo uses your palm. one palm = 25g. you carry it with you. always.
it’s not discipline. you have plenty of that.
you’re missing the system. klyo is the system.
the system
four mechanisms.
zero willpower required.

questions
everything people ask before they start
how do I gain weight if I'm never hungry?
appetite follows routine, not the other way around. eat by the clock instead of by hunger, lean on calorie-dense foods and liquid calories, and let klyo's Top Up suggestions close the gap when you're behind on your daily number.
how many calories do I need to gain weight?
most people gain steadily on their maintenance calories plus a 250-500 calorie surplus. klyo calculates your personal daily target with the Mifflin-St Jeor equation - the same formula dietitians use - and adjusts it to your goal.
how is klyo different from MyFitnessPal and other calorie counters?
most trackers are built to help you eat less - red warnings when you go over, streaks, guilt. klyo is built for the opposite problem: it shows you what's left to eat, suggests what to add when you're behind, and never shames you for eating more.
does klyo work for hard gainers and ectomorphs?
that's exactly who it's for. if you train hard, eat 'a lot' and still can't gain weight, the gap is almost always unlogged calories. klyo makes hitting a surplus the default instead of a daily battle.
can I log meals with a photo?
yes. snap a photo of your plate and klyo's AI estimates the calories and protein in seconds. you can also just type a sentence like 'chicken bowl and a coke' - no database digging.
is klyo free?
the core is free: your daily calorie target, manual logging, and Quick Wins snack suggestions. klyo Pro adds AI photo logging, unlimited logging, and unlimited coach conversations - $59.99/year with a 7-day free trial, or $9.99/month.
will eating in a surplus make me fat?
a controlled 250-500 calorie surplus with enough protein puts on weight at roughly 0.25-0.5% of bodyweight per week - mostly muscle when you're training. klyo keeps the surplus measured, so you gain on purpose, not by accident.
is klyo available on Android?
klyo is on iPhone today. the Android version is in review and on its way - the journal and guides on this site are free for everyone in the meantime.
