What They Have in Common
Both are radar-free — the MLM1 uses Doppler radar paired with your iPhone camera, while the Square Golf Original uses high-speed photometric cameras beside the ball. Both require special balls for reliable spin data, neither has a built-in display, and neither requires club face stickers. That's about where the overlap ends.
Where They Differ
Technology & What Each Is Actually Good At
The MLM1 pairs Doppler radar with your iPhone camera to track ball flight. It works outdoors and indoors, though spin accuracy indoors without RCT balls is inconsistent — radar without actual ball tracking struggles with spin in short ball flights.
The Square Golf Original is photometric — high-speed cameras capture the ball at the moment of impact from a beside-the-ball position. That approach tends to produce very clean club data (swing path, face angle, dynamic loft, angle of attack) because the camera is capturing what actually happens at impact, not inferring it from Doppler signal. The tradeoff: it's indoor-only. There's no outdoor use case for a photometric setup like this.
If I had to bet, the Square Golf Original is the more accurate of the two for club data in a controlled indoor environment. The MLM1 is more flexible about where you use it.
Subscriptions and Total Cost of Ownership
This is where the comparison gets interesting.
The MLM1 is $249.99 upfront, but full functionality — shot tracer, slow-motion replay, R-Speed — requires the MLM1 Premium subscription at $99.99/year.
Over three years, that's $249.99 + ($99.99 × 3) = ~$550 total.
Over five years: ~$750 total.
The Square Golf Original is $699 upfront with no subscription. Ten courses are included. GSPro is compatible (you'd need a GSPro license separately — typically $250 one-time — if you want more courses, but that's optional).
At the three-year mark the Square Golf Original is already cheaper in total spend. By year five, it's meaningfully cheaper, and you've got better club data and sim access the whole time. That math matters.
Data Depth & Club Metrics
The MLM1 tracks the core ball flight metrics: carry, total distance, ball speed, club speed, launch angle, launch direction, smash factor, side carry, apex, and spin rate. That's solid for what most range sessions need.
The Square Golf Original goes further. It adds swing path, face angle, dynamic loft, and angle of attack — the club data that actually tells you why your ball did what it did. For anyone working on swing mechanics or trying to understand miss patterns, that extra layer is useful.
Sim Software & Indoor Range
The Square Golf Original comes with 10 courses and connects to GSPro. If you're building an indoor sim space, that's a real advantage — you have a playable sim from day one.
The MLM1 has a virtual range inside its app. It's not a full sim — more of a visualized practice environment. If you want to play full 18-hole virtual rounds, the MLM1 isn't built for that.
Portability & Outdoor Use
The MLM1 wins this one cleanly. It's small (~5 × 3 inches), runs on a ~4-hour battery, and you can take it to any outdoor range as long as you have your iPhone and decent lighting. The Square Golf Original doesn't do outdoor use at all — it's an indoor-only setup.
Special Ball Requirement
Both require special balls for full spin data. RCT balls (MLM1) and dotted balls (Square Golf Original) both run roughly $70 per dozen. Budget accordingly — if you're practicing several times a week, that's a real ongoing cost on top of everything else.
Who Should Buy Which
Rapsodo MLM1 — you're the golfer who:
- Practices primarily at an outdoor range and wants to know real carry numbers without carrying a $1,000+ device
- Is solidly in the Apple ecosystem (Android? The MLM1 isn't for you — iOS only, full stop)
- Wants a low barrier to entry — $250 gets you working data on day one
- Doesn't need club data or sim capability; you want to know how far you actually hit your 7-iron
Square Golf Original — you're the golfer who:
- Has or is building a dedicated indoor hitting space
- Wants club data — face angle, swing path, angle of attack — not just ball flight
- Plans to play virtual rounds and wants real course sim via GSPro
- Hates subscriptions and wants to pay once and own it
- Practices frequently enough that the $449 premium amortizes quickly (and based on the TCO math, it does)
The Bottom Line
The MLM1 is a solid range tool for golfers who want portability and affordability, and it earns its price for outdoor practice. But the Square Golf Original is a genuinely different product — it's for indoor sim use, and it delivers better club data with no ongoing fees. Over three or more years, the Square Golf costs less and does more in its intended environment.
If you're choosing between these two for a sim room setup, the math and the feature set both point the same direction.
