What Lioness is
Lioness makes a smart vibrator with built-in sensors — a force sensor that measures pelvic-floor muscle contractions, plus an accelerometer, gyroscope and temperature sensor — and charts those signals in a companion app, including a real-time view of arousal and orgasm. Its real strength is objective, biometric data: it shows you a recorded physical signal, not just your own impression. For people who want to see measured, repeatable readouts of their body's response, that's genuinely valuable and something self-report can't replicate. It is a paid hardware device (around US$229 at the time of writing); the companion app is free.
What Orgasmly is
Orgasmly is a self-report tracker: you rate intensity and add context in a few taps, and it surfaces your patterns over time. There's no device — it runs in your browser and can be added to your home screen. Because it doesn't depend on a specific piece of hardware, it works for any kind of experience, solo or partnered, and it's free. The trade-off is honest: Orgasmly records your subjective experience, not a biometric measurement.

Which should you choose?
They're not really rivals so much as different tools. Choose Lioness if objective, measured biometric feedback is the thing you want and you're happy to buy a device to get it. Choose Orgasmly if you'd rather track without hardware, want to include partnered experiences, care about a minimal-data privacy model, or simply want to start for free today. There's nothing stopping you using both — measured data from one, broader context from the other.
