1 The bottom line
Price hardware to win users, and let the subscription carry the value. Hardware pulls people in and keeps them longer, but it adds a whole e-commerce business, so plan for that cost.
2 Key takeaways
- Price the device to bring people in, not to make money. A low entry price puts the price where the value is delivered.

Visible30:59 sells its band for roughly $80 with no margin, then charges $20 a month or $14.99 on annual.
- Build the software first and let the hardware enhance it. Retention and the use case live in the software.

Life36038:47 finds that users with Tiles retain better overall than users without Tiles.
Plaud44:25, as described by Dris of Methods, pairs a $130 device with $20 a month software.
- Sell hardware on the web and attach the subscription there. In-app purchases cannot sell hardware, and your own site lets you control the offer.

Skylight42:19 turns the subscription on by default on its own site and discounts the device, which gives a much higher attach rate than retail.
Visible55:24 built a web payment flow that avoids the 30% store fee.
- Test the subscription price and the hardware discount together. The two change each other's results.

Skylight50:28 varied both at once, modeled the result in a spreadsheet and chose $79 over a $99 option that looked a little better on paper.
- Budget for the hidden e-commerce and technical work. Hardware adds far more than a device to an app business.

Luke Martin-Fuller, Visible29:12 says the technical work is an order of magnitude harder than pulling from an API.
The hardware should enhance the software and not the other way around.

2.1 Decide what the hardware is for
Hardware is a way in and a way to keep users, so set its role before you set its price.
- Use the device as a top-of-funnel and retention tool.

Giordano Contestabile, Life36038:47

Life36038:47 sells Tile and pet GPS devices to bring in users.- It also bundles free Tile offers into its subscriptions.
- Users with Tiles retain better because the device adds to an existing use case.

Life36038:47
- Build the software first, then give people a reason to add hardware.

Dris, Methods44:25
- Good software is what makes someone want the device.
- Plaud's tiny device means you do not need the app open or always recording.
- Plaud pairs a $130 device with $20 a month software and has one clear niche.

Dris, Methods44:25
- Price the device at cost and let the subscription carry the value.

Luke Martin-Fuller, Visible30:59

Visible30:59 sells its band for roughly $80 with no margin.- It then charges $20 a month, or $14.99 on annual.
- This lowers the barrier to entry and matches price to where the value is delivered.
- Oura charges a high upfront price and a low subscription. Whoop folds hardware into a pricier membership. Tractive keeps the barrier low and earns on the service. Visible chose the Tractive-like model.

2.2 Get the device made and plan the load
Partner for the sensor, and budget for the work that hardware adds.
- Pick a hardware partner for accuracy instead of building sensors.

Luke Martin-Fuller, Visible26:53
- Start by buying existing sensors and using the open SDK to prove the concept.
- Then buy wholesale, and later co-develop a new version.

Visible26:53 co-developed for battery life, easier charging and accelerometer data.- Polar has built heart rate monitors since 1977, and 99% of devices can't support real-time heart rate alerts.

Visible26:53 - API aggregators fell short because sensors sample every 5 to 10 minutes and need a second app open. That is a poor fit for people with brain fog.

Visible26:53
- Budget for the hidden e-commerce and technical load.

Luke Martin-Fuller, Visible29:12
- Plan for inventory, financing, fulfillment, boxes and refunds.
- Expect hard technical work on Bluetooth, sync frequency, background operation and firmware updates.
- Learn from benchmark e-commerce companies with great product pages and technical specs.
- Free trial best practices do not apply to hardware.

Visible29:12 - In his words: "You bolt on what is essentially an entire e-commerce business to what otherwise could just be a subscription app business."

Luke Martin-Fuller, Visible29:12
2.3 Price the device and the subscription together
Test the two prices as one system, and keep a cushion for shocks.
- Vary the subscription price and the hardware discount at the same time.

Michael Segal and Mark Ungerer, Skylight50:28
- The two prices together change hardware conversion, margin per unit and subscription attach.
- Model the combined outcome in a spreadsheet before you choose.
- The

Skylight50:28 test landed on $79. A $99 price looked a little better on paper and was rejected.
- Keep some hardware margin as a cushion.

Michael Segal and Mark Ungerer, Skylight28:20

Skylight28:20 did not run hardware at zero contribution.- That gave it dry powder against tariffs and the memory price spike.
- It holds prices and gives up hardware profit this year.
- A price cut stays available later to reach 20 million households.

Skylight28:20
2.4 Sell it online and attach the subscription
Your own web checkout is where you control the payment, the offer and the attach.
- Sell the hardware on the web, not through in-app purchase.

Luke Martin-Fuller, Visible55:24
- You can't sell hardware via in-app purchases, so

Visible55:24 built a web payment flow. - That gave it HSA and FSA payments and better attribution signals back to ad platforms.
- It also avoids the 30% store fee.
- Other companies could add localized payment methods or buy now pay later via Stripe.

Visible55:24
- You can't sell hardware via in-app purchases, so
- Discount the hardware when people sign up with the subscription on your own site.

Michael Segal and Mark Ungerer, Skylight42:19
- On skylight.com the subscription is turned on automatically, and the hardware is discounted if you sign up with it.
- It looks like a great deal with a free month. Users can opt out, but most don't.
- The owned channel has a much higher attach rate than retail. Amazon and retailers cannot make this offer.

Skylight42:19
- Send QR code scans to Apple in-app purchase to cut checkout friction.

Michael Segal and Mark Ungerer, Skylight56:31
- Non-subscribed users on the

Skylight56:31 device used to scan a QR code that led to a web checkout. - With in-app purchase, a mom could scan, subscribe and be done.
- Conversion from the QR flow rose over 100%, measured on a smaller group of users.

Skylight56:31 - Web checkout costs more than the headline 30% saving suggests, because extra clicks and UI weirdness lose conversion.

Skylight56:31
- Non-subscribed users on the
2.5 Widen the funnel with a free app and retail
Let people try the software before they buy, and use retail to build trust.
- Offer a free app tier to de-risk the hardware purchase.

Luke Martin-Fuller, Visible1:00:44
- Hardware cannot have a free trial, so a free app lets people feel the quality before they buy the wearable.

Visible1:00:44 barely promotes it, with a tiny section on the website.- The free app is still a really big chunk of acquisition, through word of mouth.

Visible1:00:44 - PMF survey scores for the wearable membership are far higher than for the free app, so the paid product stays the clear upgrade.

Visible1:00:44
- Sell through your own site, Amazon and retail, and teach buyers after the sale.

Michael Segal and Mark Ungerer, Skylight40:38

Skylight40:38 sells on its own site, Amazon, Costco, Best Buy and internationally.- Retail is the biggest influencer and a stamp of quality, and retailers typically take only one player in a category.
- Subscription attach is lower in retail, so post-purchase education matters more.
- Being everywhere has driven higher overall growth, despite lower attach in some channels.

Skylight40:38
2.6 Where they disagree
How much margin the hardware should earn, and which side leads, depends on the product.
- Hardware at zero margin or hardware as a profit source.

Luke Martin-Fuller, Visible30:59: "We don't make any money on the hardware that we sell."
Skylight28:20 made about half its profit from hardware and half from software, while software is only 10 to 20% of revenue.
Life36038:47 sits between the two. It indexes toward reaching more users rather than maximizing device margins, yet its devices are not a loss leader.
- Software first or hardware first.

Dris, Methods44:25 says the hardware should enhance the software.- Many AI wearables do the reverse. They lead with hardware and use software to prop it up.
