Every treadmill phone holder puts your phone where you can see it. TreadFrame puts it where it can see you: portrait, at distance, and steady at running speed.

A viewing mount wants your phone close, low, and tilted up at your face. A filming mount wants it back far enough to frame your body, high enough to avoid a low angle, and tilted down at you.
You cannot do both with one position. The market solved the first and sold it as though it solved both.
The console makes it worse. It is the closest surface to you, it is covered in the controls you need, and on most machines it is the part that moves most.
Mounts to the side rail, off the display panel entirely. Your speed and incline controls stay clear, and the mount sits on the stiffest part of the machine rather than the part that flexes.
Silicone grommet suspension between clamp and arm, with durometer selected for treadmill oscillation. This is the part that makes or breaks the design.
Fixed in portrait with a positive detent. Sized for a tall, top-heavy phone rather than one lying flat, and with no rotation knob that can work loose under vibration.
A screw clamp on a straight rail section. No suction cups, no adhesive pads. Neither survives repeated load cycling on a machine that vibrates every day.
Phone mount vibration is a solved problem on motorcycles. Quad Lock and RAM both sell silicone grommet damping modules, and they work well on an engine.
They are tuned for a different source. Quad Lock's own support documentation states that its grommets are specifically tuned to dampen higher frequency vibration, and that users may notice more movement at lower frequencies. For an engine, that is the correct choice.
Belt and deck oscillation sits lower. Lower in frequency and lower in amplitude than an engine, which puts it closer to the band those modules explicitly do not target. Fitting a motorcycle damper to a treadmill addresses the wrong part of the spectrum, which is why shake keeps showing up in reviews of mounts that already have one.
TreadFrame moves the damping stage to the base of the arm and selects grommet durometer for that lower band instead.
| Product | Type | Price | Portrait | Filming distance | Vibration handling | Verdict |
|---|---|---|---|---|---|---|
| Moment Strap Anywhere | Silicone strap, MagSafe | ~$40 | Yes | No | Rigid — no isolation | Best bar-attach option available. Portrait works. Transmits all deck vibration directly to the phone. |
| Belkin Magnetic Fitness Mount | Magnetic, MagSafe | ~$40 | Yes | Varies | Rigid — no isolation | Well-made and widely available. Needs a flat steel surface. No vibration isolation — shake passes straight through. |
| BeGenZ MagBolt | Magnetic, creator-focused | ~$35 | Yes | Varies | Rigid — no isolation | Marketed at gym creators specifically. 360° rotation. No damping stage — shake at running pace is the same as any rigid magnetic mount. |
| Quad Lock Vibration Dampener | Damper module add-on | ~$25 | Yes | n/a | High-band only | Genuine damping — but tuned for motorcycle engine frequency. Quad Lock's own documentation notes more movement at lower frequencies. Wrong band for treadmill deck oscillation. |
| Floor tripod (any brand) | Free-standing | $14–40 | Yes | Yes | None needed | The honest best answer when floor space exists. Portrait, filming distance, and zero vibration for under $40. Only fails when there is nowhere to put it. |
| TreadFrame | Rail clamp, damped arm | TBC | Yes | Yes | Low-band tuned | Rail-mounted for filming distance and portrait lock. Damping stage tuned for treadmill deck oscillation, not engine frequency. |

TreadFrame is produced against the specification above, in small batches — not run continuously, and not held in stock waiting for buyers. Get in touch and we'll add you to the next run.
No crowdfunding push, no warehouse of stock waiting for buyers. Small batches, made because someone needed one, not on a fixed schedule.
We'll reply directly. No marketing list, nothing sold to anyone else.
TreadFrame is an independent design project, not a funded company.
