Taller App Review: Which "Taller" Are You Even Looking At?

Which "Taller" app are you looking at?

User reviews and social posts constantly mix these up — one app's angry customers sometimes review the other. Here's the untangling nobody else seems to have written down:

This review covers the two big ones in detail. If someone recommended "the Taller app" without a link, they almost certainly meant the first.

Is the Taller app legit?

Depends what "legit" means. As a business: yes. Taller (Virtual Network) is an established product — an indie-business newsletter reported it earning about $840,000 a year (~$70K/month). Its marketing site claims "98.5% Accurate" and "500,000+ men." These apps are not scams in the malware sense: you get a real app with real content.

As a prediction: unverifiable. Neither app publishes its formula, a validation study, or an error range. Taller's listing says it builds a plan "to potentially increase your HGH production" — note the word "potentially" — and invites you to "leave the short king zone behind." The "98.5% accurate" figure appears on its own site with no source or definition of what's being measured. We wrote a whole piece on what height-predictor accuracy claims actually mean; the short version is that an accuracy percentage without a published method is a marketing sentence, not a measurement.

And on what the apps promise versus what users hear: the store listings carefully avoid promising centimeters. The disappointment shows up anyway —

"They promised 4 inches in 2 months… The only thing that maximized was my disappointment."
— public App Store review of Taller (the "promise" is the reviewer's characterization; the listing itself makes no such claim)

How much does the Taller app cost?

Both major Taller apps run several prices for the same plan simultaneously (standard A/B price testing — the offer you see may not be the offer your friend sees). From their public App Store in-app purchase lists:

Taller AI is the expensive one — up to $9.99/week or $99.99/year, with no lifetime option — and it's also the one with the sharpest billing complaints in public reviews, including an explicit "$44" auto-renewal charge a reviewer called out while using the word "scamming." Weekly plans deserve extra caution in general: $5.99/week is $311/year if you forget to cancel.

Does the Taller app actually work?

Split the question in two, because the app sells two different things:

The prediction: can't be evaluated, because the method is secret. That's not an insult — it's just the epistemic situation. A prediction you can't check is a vibe with a number attached.

The habit plan: the ingredients are real — sleep matters most for growth hormone, posture work can genuinely reclaim 1–3 cm of slouched height (about ½–1 inch), exercise and protein support normal growth. None of it is proprietary, and none of it makes bones grow longer after your growth plates close. No app can. Taller's own fine print concedes this: "Taller does not provide medical advice. All suggestions are based on common growth-promoting practices."

Both sides of the review pages tell the same story from different moods:

"All it does it make you answer some questions and then you have to do their stupid overpriced subscription."

"I was 5,7… i grew a whole 3 inches because of this app i am now 5,10."

What users say about Taller

The praise: at 4.7★ across tens of thousands of ratings, the majority experience is clearly positive — recurring themes are the exercise library, the structure of having a daily routine, and motivation. Some 5★ reviews report height gains; teenagers grow, so those anecdotes are unfalsifiable in both directions, which is exactly why we keep pointing back at methods instead of testimonials.

The complaints cluster into three groups across both major Taller apps, in order of frequency:

• The paywall after the quiz — the single most repeated 1★ theme, quoted in the section above.
• Billing and refunds. Beyond the "$44" auto-renewal complaint, one Taller reviewer says their refund request was met with advice to "believe harder" — their words — and concluded the app "only works in your dreams." Several note there's no way for "teenagers without bank accounts" to try it at all.
• Technical issues. Reviews mention crashes during setup on some devices, the AI coach getting stuck in loops, and — for Taller AI specifically — the app freezing after measurements are entered until a subscription is bought.

How to see your results without paying

The most-searched Taller question on TikTok is some version of "how do I reveal my results without paying?" Straight answer: inside the app, you can't. The paywall placement is the business model — the quiz builds anticipation, the subscription screen cashes it in. There's no hidden setting.

Two things you can do instead:

• Run the calculation free on the web. A quiz-based height projection needs your age, sex, height and (optionally) parents' heights — and the math, unlike the apps' versions, is published science. Our free calculator does it in your browser in about a minute: predicted adult height, an honest range, and the formula documented on the page. No app install, no account, and your answers never leave your device.
• Don't install "premium unlocked" APK/IPA files. Searches for cracked versions of Taller are common enough that suggestion engines autocomplete them. Modded binaries from outside the official stores are a classic malware channel, and on a phone that's usually a teenager's, that's a bad trade for a number you can get free legitimately.

When the Taller app is worth it

The honest section. Taller (Virtual Network) is a defensible purchase if:

• You want coaching, not just a number. Its 100+ exercise library, routines, a 24/7 AI coach and community discussions are real product depth — that's what the subscription actually buys.
• Accountability features keep you going. If reminders, streaks and a paid commitment genuinely change your behavior, the sleep and posture habits it pushes are good habits.

What you're paying for is the coaching wrapper. Just know that's the purchase — not secret height science.

Free alternatives to the Taller app

Being precise, because "free alternative" hides a trap: there is no fully-free alternative for the coached-program part. Every serious habit-coaching app in this niche charges. What can be genuinely free is the prediction:

• GoTaller's web calculator (ours): prediction + range free in the browser; the height comparison tool adds your percentile by age. The app keeps prediction and percentile free forever and charges only for the daily habit plan ($5.99/week, $24.99/year with a 3-day trial, or $34.99 lifetime).
• GoTall: the category's biggest app — but its result also sits behind a subscription, so it's an alternative, not a free one. Full GoTall review here.
• Any pediatrician's growth chart: the genuinely free, genuinely validated option — worth saying out loud. For anything unusual (very tall/short for age, growth suddenly slowing), that's a doctor conversation, not an app decision.

Taller app FAQ

Is the Taller app legit?

The Taller apps are real products from real companies — reporting puts the biggest one at roughly $70,000/month in revenue — and they are not malware. "Legit" gets complicated on the prediction itself: no Taller app publishes its method, so the accuracy of the number it sells cannot be independently checked, and the habit advice (sleep, posture, exercise) is standard guidance rather than proprietary science.

Is the Taller app worth it?

If you want a structured, coached routine — a large exercise library, reminders, a community — and the subscription price is acceptable to you, Taller has real content behind the paywall. If you mainly want the height prediction, it is not worth paying for: the same class of calculation is published science and available free.

Is the Taller app free?

The download and quiz are free, but the prediction result and all plan features require a subscription. Public reviews consistently describe completing the questionnaire and then being unable to see results without paying.

How do I cancel a Taller app subscription?

Billing runs through Apple or Google. On iPhone: Settings → your name → Subscriptions → find Taller → Cancel. On Android: Play Store → profile → Payments & subscriptions → Subscriptions. Canceling stops renewal but does not refund past charges.

Can I get a refund from the Taller app?

Request it from the platform, not the developer: reportaproblem.apple.com for iOS purchases, or Google Play order history on Android. Public reviews describe developer-side refund requests going unanswered, so the store route is the practical one.

Is the Taller app safe?

The official store versions are safe to install in the malware sense. Two cautions: subscription auto-renewal has generated billing complaints, and "free premium" APK or IPA versions from outside the official stores are a real malware risk and also violate the developer's terms — don't install those.
