Straight answers.
What it is, when it ships, how the app works, and how we talk about it.
What is Rebow?
An app-guided eccentric loading device for the elbow. It's a purpose-built "mass on a stick" — a telescopic bar with a small weighted head and an integral phone mount — paired with an app that paces each rep and logs your load in newton-metres.
Who is it for?
Anyone doing eccentric loading for their elbow — climbers, tradies, tennis and golf players, and people with lateral or medial epicondylitis. It's also designed to be useful to physios and clinics who want a device that measures what their client is actually doing at home.
Does Rebow treat tennis elbow?
We don't make treatment claims. Rebow is an exercise and recovery device: it delivers and measures a proven exercise method — eccentric loading — which is the approach that underpins the clinical guidance for tendinopathy. Whether that kind of loading is right for you is a conversation for your physio or GP. Rebow makes doing it well easier; it isn't a diagnosis or a medical device.
How is it different from a FlexBar or a dumbbell?
A rubber bar proved eccentric loading works at home — but it can't tell you how much load you're applying, pace your tempo, or track your progress. A dumbbell is a blunt, fixed weight. Rebow's adjustable moment arm sets a precise, fine-tunable load, and the app measures and records it. The measurement is the difference.
Do I need my phone to use it?
Yes — your phone is the motion sensor. It mounts rigidly to the device and the app uses its accelerometer to pace and log each rep. The app is a progressive web app (runs in the browser, installs to your home screen), so there's nothing to download from an app store.
When will it ship?
Estimated delivery is March 2027. That's a buffered estimate, not a floor — hardware crowdfunding ships late, and freight and quality checks are the usual variables. We'd rather under-promise and deliver.
How much will it cost?
Pricing is being finalised with our manufacturer and will be confirmed at the Kickstarter, with early-bird units for backers who get in first. For now you can join the free waitlist or reserve an early-bird spot for $1.
Where do I buy it?
Rebow launches on Kickstarter first. Join the waitlist and you'll get the notice the moment it goes live; reserve for $1 and you're pointed straight to the campaign.
How do I stay updated?
Join the waitlist with your email. You'll get the launch notice and the occasional build update — no spam, unsubscribe any time.
