SingleArm

Be your own baseline—A/B test yourself

SingleArm helps you learn from real-world health experiences by tracking changes over time. You set a baseline, observe changes, and reflect on outcomes with clarity and transparency, allowing you to understand what works for you while respecting your data and boundaries. It is for learning, not medical advice.

Free to use with some features requiring AI credits. Four AI credits are included with every new account, and you can use coupon code PHSTARTER to redeem an additional five AI credits.
