## What is byrna?

Byrna turns training into a system. Get an AI strength coach that builds and adapts your program, track every set, and watch your Byrna Score climb from 300 to 850 as you get stronger.

And it's more than fitness — a Bible verse of the day and a devotional meet you every morning, so you train your spirit alongside your body.

Most fitness apps just log what you did. Byrna tells you what to do next — and shows you the progress to prove it's working.

Bug Fixes

### 1.3 — 2026-08-12

NEW: AI Suggested Meals — open "Suggested meals" on the Nutrition tab for 5 recipes built around your goal and macros, each with a full recipe you can log in one tap (Premium). Your AI coach can now add timed cardio like runs and walks, and longer cardio sessions log cleanly up to 60 minutes. Plus: supplement reminders stay on time when you travel across timezones, and we fixed a crash when editing a cardio day.

### 1.2 — 2026-08-10

NEW: Daily Devotional — free for everyone

Byrna now starts your day with faith, not just fitness. A Bible verse of the day sits at the top of your Today screen — tap it to open an AI-built Bible study and go deeper. Choose the depth that fits you (short, medium, or long), keep your own notes saved right in the app, and export or share them anywhere. Your full devotional history is always one tap away.

Plus performance improvements and bug fixes. Thanks for training with Byrna.
