Mobile app: Users start their day viewing health scores, trends and insights from wearables in a glance—a check-in tool used in brief daily moments, not sustained work. Sample screens on a phone, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Evenbeat is a web app that turns data from the smartwatch or fitness tracker you already own into a clear daily picture: how you slept, how recovered you are, and where your resting heart rate is heading. You import data from your phone's health store or a device export.
It is for people who want continuous-style tracking without a monthly fee. The material behind this proposal reports that users find a $350 subscription prohibitive and move to one-time-purchase devices, though some find those devices' features weaker. Evenbeat adds the analysis layer for a single payment.
Evenbeat is not a medical device. It shows patterns and flags unusual readings so you can raise them with a doctor. It does not diagnose.

- Why this name

PricingAI proposal
The material gives only a public claim that Whoop costs $350 and is seen as too expensive; it has no verified pricing page. The $39 one-time price is a starting point to test.

What it could be worthEstimate

If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Users send a doctor summary PDF or a weekly sleep card to a doctor, partner or friend. Each carries the Evenbeat name and a link to try the free tier.
- Do they become customers?
- Recipients can become buyers if they own a tracker, but doctors mostly only see it. Test whether shared weekly cards lead friends to import data and buy.
- First customers
- Owners of one-time-purchase fitness trackers who say they left or avoided a subscription wearable and want better sleep and heart insight.
- Where to reach them
- Hacker News and Reddit threads: Join threads on wearables and subscription costs, share the free tier and ask for feedback on the import flow.
- Quantified-self communities: Offer early access to people who already export their wearable data and want clean trend views.
- First milestone
- Fifty free sign-ups who import data, and ten paying $39 customers within 60 days of launch.
Why people already pay for this
- Public claimWhoop charges $350 for subscription and users view this as prohibitively expensive.
- AI inferenceUsers are switching from subscription-based wearables to one-time-purchase alternatives specifically to avoid subscription costs.
- Public claimPremium wearables like Whoop struggle with business viability at high subscription price points.
- AI inferenceFitbit Air offers competitive sleep tracking to premium subscription devices without requiring ongoing fees.
- AI inferenceOne-time-purchase wearables can offer advanced health features like automatic AFib detection.

RisksAI inference
- RegulatoryHeart rhythm features may be treated as medical claims. Wording must stay informational and legal review is needed before launch.
- PlatformA web app cannot read phone health stores directly. Users must export or import files, which may feel clumsy and limit sign-ups.
- CommercialThe problem as stated is about hardware. Users may want a device, not an analysis app for a tracker they already own.
- DataExport formats differ by brand and change often, so parsers need ongoing upkeep.
- CommercialA one-time price gives no recurring revenue to pay for support and updates; the price must be tested.
