### 5/5 — Box breathing at your convenience

*2026-04-26*

Designed by a master in the practice! Really helped me down regulate before bed

### 5/5 — Breath work

*2026-04-21*

I’ve been using Ground by Collin Chartier consistently, and it’s honestly one of the most useful apps I’ve added to my daily routine.

I run it in my vehicle between appointments, and it’s been a game changer for staying focused, grounded, and mentally sharp throughout the day. The guided breathwork is simple but extremely effective, whether I need to reset, boost energy, or calm down.

What really sets it apart is the testing and data. The CO₂ tolerance/VO₂-type testing features give real, measurable insight into performance and recovery, which is something you don’t usually get in a breathwork app. It feels more like a performance tool than just meditation.

The interface is clean, the sessions are easy to follow, and it fits perfectly into a busy schedule. No fluff—just powerful, practical tools that actually work.

Highly recommend this app to anyone looking to improve focus, performance, and overall well-being.
