Symmetry Built Its Own "Rank System" for the Gym. It's Not Indexed for "Gym Rank" Anywhere — a Rival Literally Called Ranked Gym Workouts Owns It in All Three Countries.
Symmetry pitches an AI body scan that finds your weakest muscle groups, then turns every one of 300+ exercises into something you can "rank up" like a video game character. It's a real, working differentiator — 5,963 reviews at 4.8 stars, an estimated 470,000 installs, English-only listing. In its home market, Spain, it sits at #8 in the Health & Fitness chart and search rank #2–5 for the category's core terms. In the US and UK — App Store markets roughly ten times the size of Spain's — it doesn't chart at all, and it isn't indexed for the exact phrase that describes its own signature feature.
What Symmetry actually does
Take a photo, and Symmetry's AI scans your physique to flag your strongest and weakest muscle groups. From there it builds a fully personalized training plan — gym, calisthenics, or home — and calculates progressive overload for you instead of making you guess a weight. The feature it leads with in its own screenshots is the "Rank System": every one of 300+ exercises has a level, and leveling one up is built to feel like progressing a character in a game rather than filling out a spreadsheet. Version 7.12.0, last updated September 10, 2026, 161 MB, built entirely in English despite a developer site (symmetry.club) and in-app testimonials that read unmistakably Spanish — Miguel Ortiz, Carlos Tejero, Mauro Botanes.
Chart rank: dominant at home, absent everywhere else
| Country | Symmetry (Health & Fitness, top-free) |
|---|---|
| Spain | #8 |
| United States | not in top 100 |
| United Kingdom | not in top 100 |
| Canada | not in top 100 |
| Australia | not in top 100 |
A #8 spot in a category chart with no paid boost is a real result — Symmetry is genuinely popular in Spain. But this is a Health & Fitness chart dominated by Strava, Planet Fitness, MyFitnessPal and Oura at the top: apps with tens of millions of installs and years of habit-forming daily use behind them. In that kind of chart, download velocity matters more than review count, and an app with 470K lifetime installs can sit outside the top 100 in the US simply because bigger, older apps out-download it every day — chart rank here says less about Symmetry's quality than it does about the size of the apps it's standing next to. Search rank is the more honest read of whether Symmetry can actually be found.
Search visibility: strong in Spanish, thin in English
| Keyword | US | UK | Spain |
|---|---|---|---|
| gym app | #17 | #56 | #2 |
| gym workout log | #24 | #42 | #2 |
| workout log | #28 | #53 | #5 |
| gym tracker | not indexed | #28 | #3 |
| ai workout plan | #34 | #54 | not indexed |
| ai body scan | #49 | #42 | not indexed |
| gym rank | not indexed | not indexed | not indexed |
Every core term is 2–17x better in Spain than in the US, on a listing that's identical, word for word, in every country — Symmetry never translated anything, so this gap isn't a metadata problem. It's a popularity problem: the app has years of accumulated engagement and word-of-mouth in Spain that it simply hasn't built yet in the US or UK, and Apple's search ranking rewards exactly that kind of proven local traction. "Ai workout plan" and "ai body scan" are the two terms that describe what actually makes Symmetry different from a plain logging app, and both sit past position 30 in its two largest potential markets.
Hevy: the direct competitor that solved this exact problem
Hevy Studios is, per its own App Store developer page, also an "S.L." — a Spanish limited company, same as Symmetry's home base. The difference is Hevy shipped its listing in 16 languages, including Arabic, Japanese, Korean, and Chinese, not just Spanish and English. The result:
| Keyword | Hevy US | Hevy UK | Hevy Spain |
|---|---|---|---|
| gym tracker | #2 | #1 | #1 |
| workout log | #2 | #2 | #1 |
| gym app | #6 | #1 | #1 |
| gym workout log | #2 | #1 | #1 |
Hevy is #1 or #2 for the exact same generic terms in all three countries, with no gap between its home market and abroad. Two Spanish-founded gym-tracking companies, same category, same core keyword set — one built a listing that travels, the other hasn't left Spain yet in anything but download count.
Liftoff owns the one word Symmetry already built its product around
Liftoff's own App Store description opens with "Download the #1 gym rank app & join over 3 million lifters today!" It's the closest conceptual match to Symmetry on the entire chart — same core mechanic, workouts translated into game-style ranks and levels, right down to the leaderboard framing. Its listing is English-only, same as Symmetry's. The difference is that Liftoff claimed the word "rank" directly, in its name and its description, and it shows:
| Keyword | Symmetry (US/UK/ES) | Liftoff (US/UK/ES) |
|---|---|---|
| gym rank | not indexed / not indexed / not indexed | #1 / #1 / #1 |
| ranked gym | not indexed / not indexed / not indexed | #1 / #1 / #1 |
| gym tracker | not indexed / #28 / #3 | #6 / #5 / #8 |
| ai body scan | #49 / #42 / not indexed | not indexed / not indexed / not indexed |
Symmetry ships the same core gamification mechanic Liftoff built its name around, calls it a "Rank System" in its own screenshots and description, and doesn't come up for "gym rank" or "ranked gym" in any of the three markets checked. Liftoff, with an English-only listing and no unusual localization effort, owns both terms outright everywhere — this isn't a translation story, it's a metadata story. The one place the comparison flips is "ai body scan," where Liftoff has no presence at all and Symmetry holds a weak but real #49/#42 in the US and UK. That's Symmetry's actual open lane, and right now it's the only term on this list where that's true.
Is "gym tracker" demand even worth chasing right now?
Google Trends for "gym tracker" in the US held in the 30–60 range from March through June 2026, then dropped hard: by early August it was sitting at 6–9, and it's stayed there through the first week of September. "Ai workout plan" shows the same pattern — a single spike to 100 the week of March 29, then a flatter 15–24 range through June, falling to single digits by August. Both searches are cooling in the US right now, not rising. That doesn't erase the gap described above — Symmetry not being indexed for its own core feature is a real, fixable problem regardless of trend direction — but it does mean the generic "gym tracker" fight is a shrinking pie in the US at the moment. "Ai body scan," the term Symmetry already holds a foothold on and neither competitor here has touched, is the one worth building around rather than chasing the broader, cooling term.
What this means for Symmetry specifically
- Add "rank," "ranked," and "gym rank" to the keyword field and subtitle. The feature already exists and is already the headline pitch in the app's own screenshots — it's absent from the exact phrase that names it.
- Lean into "ai body scan" rather than the generic "gym tracker" fight. It's the one term in this whole comparison where Symmetry has real, unclaimed footing and neither Hevy nor Liftoff shows up at all.
- Treat the US and UK as a market-building problem, not a metadata one. The listing is identical everywhere; the gap tracks review count and installs, not translation. Growth there will look more like Hevy's path — building local engagement — than a quick ASO fix.
- Don't assume "gym tracker" is worth optimizing hard for right now. US search interest in the term fell from the 30–60 range to single digits between June and August 2026. The rank and body-scan terms are the more durable bets.
Data pulled from live App Store search, chart, and Google Trends results via Pumf.it on September 11, 2026. This is a read of public App Store data, not a critique of Symmetry as a product — the AI body scan and rank system are genuine, well-reviewed features. The gaps described here are keyword-metadata and market-maturity questions, not product flaws.
