Why We Picked This

This mobile app claims $5,020/mo revenue with 100% profit margin—a mathematically impossible outcome that suggests either a data entry error or a fundamental accounting misstatement. The asking price of $130K implies a 2.16x annual profit multiple, which would be exceptional if true, but the profit figure requires immediate clarification before any serious evaluation can proceed. Without corrected financials, the listing cannot be assessed on merits.

Details to confirm

  • •Monthly profit ($5,020) equals monthly revenue exactly—this 100%+ margin is implausible and must be clarified or corrected. Request detailed P&L showing COGS, operating expenses, and other costs.
  • •Confirm the revenue recognition method and whether the $5,020 figure is net of payment processing, app-store fees (typically 15-30%), hosting, or other transaction costs
  • •Request historical monthly revenue and profit statements for the last 12–24 months to verify consistency and assess growth trajectory
  • •Describe the customer base size, retention rate, and revenue concentration—a single app with this margin profile warrants scrutiny of churn and cohort economics

The core functionality—stud detection via accelerometer/magnetometer, level checking, and angle measurement—is straightforward to build using native mobile APIs (Core Motion on iOS, Android sensors). A solo founder can prototype and ship an MVP in 8 weeks using Xcode/Android Studio, costing $3.5K–$8K for development tools, testing devices, and initial app-store deployment. The primary acquisition value would be verified customer base, app-store ranking/reviews, and organic discovery—none of which are described in the listing. Without evidence of customer count, retention, download velocity, or organic traffic, the software alone does not justify a $130K acquisition price. The unresolved financial data (100% margin claim) further reduces confidence in the business traction being purchased.

Cash estimate includes the AI tools, APIs and infrastructure needed for a solo founder to recreate the software. Build time is informational and lightly weighted. The verdict is driven mainly by customers, users, verified earnings, retention, distribution, brand, data and operating history.
