I built a lifting app that counts reps from a side-on phone camera and shows RIR as a range, not a number. Looking for feedback

I lift, and the part of autoregulation I never trusted was my own RIR guess at the end of a hard set. So I've been building RIRVana, an Android app that watches the set from a side-on phone camera. What it does right now: live HUD during the set with a measured rep count estimated RIR shown as a range with a confidence level (for example: RIR 2, range 1 to 3, medium confidence). It is never presented as a measurement. the next working set adjusts based on how much you actually slowe

痛点：举重爱好者难以准确估计RIR（剩余次数），导致自动调节训练强度不可靠。

目标用户：进行自动调节训练的举重爱好者、力量训练者、力量举运动员。

证据：the part of autoregulation I never trusted was my own RIR guess at the end of a hard set.

变现：订阅制（如每月$5-10），提供高级分析、训练计划调整、数据导出等。

MVP：使用MediaPipe或ML Kit实现侧面摄像头计数和基于速度的RIR范围估算，先做Android端，用简单UI展示实时计数和RIR范围，手动输入训练日志。

竞品：RepCount、Strong、Hevy、FitnessAI、Form

摘要：开发者推出RIRVana，一款通过侧面手机摄像头计数并估算RIR范围的Android应用，目前免费内测，定价未定。该应用旨在解决自动调节训练中RIR估计不可靠的痛点，但尚未有用户付费验证。
