GoTall App Review: What You Get Before — and After — Paying

What is GoTall?

GoTall is a height-prediction and growth-habit app sold on the App Store (as "GoTall - Height Predictor", by Grow Labs LLC) and on Google Play (as "GoTall", listed under President Life Holdings Ltd.), with its own site at gotall.app. As of July 14, 2026 it shows 4.6★ from 6.8K ratings on iOS and 4.8★ from 10.7K reviews with 100K+ downloads on Google Play, and it's actively maintained — last Play update June 16, 2026.

The flow: you answer a lifestyle quiz (age, height, parents' heights, sleep, nutrition, puberty stage), the app builds a "projection of your potential adult height," and a premium plan promises habit routines — in the listing's words, a plan "designed to support natural HGH production and optimal growth." Its Play description opens with "Trying to break out of short king territory?" — which tells you exactly who it's talking to.

One thing GoTall does not do is publish its prediction method. The iOS listing says it uses CDC data and looks at "everything together" instead of "guessing from just your age" — more than most rivals disclose, and users notice: one reviewer praised that it "uses the same CDC data" as a doctor's office. But the actual formula is not published anywhere we could find, so the accuracy of the projection can't be independently checked. (For how the main prediction methods compare, see how accurate are height predictors.)

Is GoTall free?

The quiz is free. The result is not. You can download GoTall and answer every question at no cost — but public reviews consistently describe hitting a subscription screen before the prediction is shown:

"After spending time answering everything, the app does not provide the result unless you subscribe."
— public App Store review of GoTall

"Wasted all of my time just to make me pay at the end."
— public App Store review of GoTall

The same pattern shows up on Android. A Google Play reviewer (February 2026) wrote that they downloaded GoTall because it advertised free tracking of nutrition and sleep, but the features are "basically unusable without paying," concluding: "it feels misleading and not worth the download."

To be precise about what the listing itself says: GoTall's Play description states that "some features, including full analysis and advanced tools, require a premium subscription or purchase." That's accurate — the disagreement between the app and its reviewers is about whether the core result counts as an "advanced tool."

GoTall pricing: what it actually costs

These are the in-app purchases listed publicly on GoTall's App Store page:

Source: public App Store listing · Last checked July 14, 2026. Google Play shows an in-app range of $0.99 – $39.99 per item.

Notice the spread: the same yearly access exists at multiple price points at once, from $9.99 to $59.99. That's standard price testing — different users are shown different offers — but it means the price you see isn't necessarily the price your friend sees, and it's how billing surprises happen. Two verbatim examples from public reviews:

"Charged $39 instead of the advertised $0.67."
— public GoTall review

"App is clearly a full on cope, that plays on teenagers insecurity and tricks them to pay a subscription to 'unlock their max height' … the pop subscription comes frequently asking you if you want the sub for a 'special price' of 0.99$ for the first week."
— public Google Play review of GoTall, March 2026

Another reviewer described accidentally buying a two-year subscription and struggling to get a response about a refund. None of this is unique to GoTall — but it's worth knowing before you enter the quiz with a payment method attached to your account.

One more verifiable detail from the Play listing's Data safety section: GoTall declares that collected data "can't be deleted" by the user. That's their own declaration on the listing, not our characterization.

How GoTall predicts your height

Credit where due: GoTall's marketing gestures at real science more than most of this category. Referencing CDC growth data and taking parental height, sleep, nutrition, activity and puberty stage as inputs is the right family of approach — growth-reference percentiles plus mid-parental genetics is how clinicians actually frame height expectations.

The problem is verification. The listing claims it's the "most accurate height predictor" (the iOS subtitle literally reads "#1 height predictor & maxxer"), but no formula, validation study, or error range is published. "We look at everything together" is a description of inputs, not a method. Any accuracy claim without a published method is a marketing sentence — that applies to GoTall and to everyone else in this niche. We keep our own formula public precisely so this criticism can't be aimed back at us: the exact WHO-based tables and mid-parental math behind our calculators are documented on the tool page itself.

What users say about GoTall

The praise is real. At 4.6–4.8★ across hundreds of thousands of installs, plenty of users like GoTall: the recurring positive themes are the CDC-data credibility, a slick interface, and the feeling of a structured plan — one widely-shown review says it gave "new hope."

The complaints are consistent. Read the 1–2★ reviews on both stores and the same three issues repeat, in order of frequency: (1) the paywall that appears after the quiz but before the result; (2) billing surprises — renewal amounts and frequent discount pop-ups; (3) refund requests and support emails going unanswered. We quoted representative examples above rather than cherry-picking the angriest ones; you can read the full review pages yourself on the App Store and Google Play.

GoTall vs GoTaller vs GrowMaxx: three different apps

If you've seen these names used interchangeably — they're not the same product, and one of them has already changed its name once. Here's the untangling:

Last checked July 14, 2026.

So if a friend told you about "the GoTaller app": this site is GoTaller. If they meant the green one with the big G icon, that's GoTall. If it had a red icon and promised centimeters in its screenshots, that was the app now called GrowMaxx.

When GoTall is the right choice

An honest review has to include this part. GoTall is the better pick if:

• You want the most established option and don't mind paying up front. It has the largest verified user base in the category (100K+ Play installs), frequent updates, and a professionally built app and website — this is not an abandoned template app.
• You want deep habit tracking. Its sleep, nutrition and exercise tracking features go further than a simple daily check-in — if you'll actually use a full tracking suite and the subscription price is fine for you, there's real substance behind the paywall.

If what you want is the prediction — the number and where you stand for your age — paying a subscription to see it is the part that makes no sense, because that calculation is not secret science. Which brings us to:

See your height prediction free — no subscription

The math behind a quiz-based height projection — growth-reference tables plus your parents' heights — is published science, and it runs fine in a web page. Our "How tall will I be?" calculator gives you the predicted adult height with an honest range, and the height comparison tool shows your percentile for your age. Free, in your browser, no account, and the formula is documented on the page. For a parent checking on a child, use the child height predictor.

What the free tools don't do is coaching: GoTaller's paid plan ($5.99/week, $24.99/year with a 3-day free trial, or $34.99 lifetime) adds the daily sleep–nutrition–posture routine. The prediction itself stays free either way — we don't think anyone should pay to see a number about their own body. And since it's the kind of thing worth stating plainly: no app, ours included, can make bones grow longer — see what height predictors can and can't tell you.

GoTall FAQ

Is GoTall free?

The GoTall quiz is free, but the height prediction result and the tracking features require a paid subscription. Store reviews repeatedly describe finishing the questions and then hitting a paywall before seeing any result.

Is GoTall legit?

GoTall is a real app from a real company with 100,000+ downloads on Google Play — it is not malware. The recurring complaints in public reviews are about the paywall placed after the quiz, surprise billing amounts, and slow refund support, not about the app being fake.

How much does GoTall cost?

On the App Store, GoTall lists weekly access from $1.99 to $5.99 and yearly access from $9.99 to $59.99, with several differently-priced versions of the same plans live at once (as of July 14, 2026). The exact price you see can depend on which offer the app shows you.

Is GoTaller the same app as GoTall?

No. GoTall (gotall.app, by Grow Labs LLC) and GoTaller (gotaller.app, by Heluva Global Media LLC) are different apps from different companies. There is also a third app that used the name "GoTaller — Height Predictor" on the App Store and has since renamed itself GrowMaxx. GoTaller — this site — shows the height prediction and percentile for free.

How do I cancel GoTall or get a refund?

Subscriptions are billed by Apple or Google, not by the app itself. On iPhone: Settings → your name → Subscriptions → GoTall → Cancel. On Android: Play Store → profile → Payments & subscriptions → Subscriptions. For refunds, use reportaproblem.apple.com or Google Play order history — public reviews report that going through the store works better than emailing the developer.
