Budget repairable GPS sports watch (sub-$300, no-frills screen-optional)
A cheap, repairable GPS sports watch for athletes who want accurate health metrics but refuse to pay Garmin's premium prices or deal with bloated smartwatch features.

One Universal Core, then the exact file layout your platform expects — CLAUDE.md, .cursor/rules, a Lovable knowledge base, a Bolt prompt under its 400-word ceiling. Evidence travels with it.

Reading an open idea needs nothing. Generating a spec from it calls a model and costs real money, so it needs an account and credits — the cost is shown before you spend anything.

Supporting evidence3
Users explicitly compare a $270 alternative favorably against a $1200 Fenix 8 Pro, showing price sensitivity at the high end of the category.
Users are actively switching away from Garmin toward alternatives like Coros over trust and pricing, and are converting others.
A subset of users want minimal, screen-optional devices for timekeeping and basic health tracking, rejecting notification-heavy smartwatch bloat.
Falsifying evidence4
This is hardware, not software: Garmin, Coros, and others already ship in this exact workflow and can cut prices or release stripped-down models faster than a solo builder can design, manufacture, and distribute a watch.
Only 5 signals, all from Hacker News, with no revenue data on any named competitor product — too thin to size real demand or willingness to pay.
Hardware unit economics for GPS watches with repairable design and quality sensors are unlikely to pencil out at consumer-friendly prices for a solo builder without existing supply chain relationships.
Charging and wear-tradeoff complaints (sleep tracking vs charging, ergonomics of inward-facing screens) are product-design nitpicks on existing devices, not evidence of an unmet market for a new entrant.
Most likely cause of death
The founder builds a watch, discovers that hardware margins, tooling costs, and certification timelines dwarf what a software MVP would require, and then watches Garmin or Coros ship a cheaper or stripped-down SKU that captures the same price-sensitive buyers with existing brand trust and distribution — while the underlying evidence base (5 HN comments, no revenue figures) never actually proved a market large enough to justify the capital this requires. Defensibility would need to come from a genuinely novel repairability/modularity angle that incumbents structurally cannot copy, not just from being cheaper.
Demand ladder
A complaint is not a customer. Weighted ×1 / ×3 / ×8 / ×15.
Counted from clustered complaint signals. No candidate-relative commercial check was applied, so no revenue is attributed to this idea.
Verified revenue: not established for this idea. No record ties a revenue figure to a product selling what this would sell.
