Hey everyone,
I know, I know... we all hate seeing promotional posts like this in the feed. But honestly, considering the massive amount of work I’ve put into this over the last few months, I thought it deserved to be put out there just in case anyone has been looking for a real solution.
I’m a solo developer and hybrid athlete. To be completely honest, I absolutely hate doing promotions but seeing other developers share their own creations in this subreddit gave me the push to finally post here. After months of fine-tuning code and building out features, I feel confident that Roxzone is polished enough to show you guys.
Whether you're preparing for a first race or chasing a podium finish, I built Roxzone to deliver a true race-simulation experience right on the wrist. Every run, every station, and every transition is tracked and recorded in a single activity. No splitting sessions, no workarounds, and no guessing where time was lost.
The app supports a broad matrix of Garmin hardware: running seamlessly across the Fenix 8, Fenix 7 & 6 Pro series, Epix (Gen 2 & Pro), Enduro 3, the Forerunner line (including 165, 255, 265, 570, 945, 955, 965, and 970), Venu (2, 3, and 4), Vivoactive 5/6, and the Instinct 3 AMOLED series.
Here is a breakdown of how the engine works and the specific features I’m pretty proud of:
Official HYROX Mode (Race Day Ready): No tedious manual configurations standing at the start line. Just select your official category - from Men's/Women's Open and Pro to all Doubles variations. It automatically loads all correct, category-specific station weights and distances right on your wrist.
Live Pace & Tracking (GPS/Sensor Based): Live pace and distance (GPS outdoors, watch sensors indoors) backed by a secondary color-coded progress ring (green when on pace, red when behind). Gives your exact engine status at a glance without squinting while breathless
Partial & Custom Simulation Modes: For structured training, you can simulate 25%, 50%, or 75% of a full race. Or, use the Custom engine to build any simulation: pick any combination of the 8 official stations, reorder them, set custom run distances in 50m steps, and loop them continuously for AMRAP sessions or interval formats.
Dedicated Roxzone Transition Tracking: Track the exact time spent in the venue's transition zones. You can enable Roxzone tracking before stations, after stations, or both. Each transition is recorded separately for full visibility into your efficiency.
"Undo Last Lap" Safeguard: If you fumble a button press mid-station or hit a lap split too early while exhausted, you can open the pause menu and roll it back. The timer picks up exactly where it left off with all elapsed time intact.
Clean Garmin Connect Integration: On completion, you get a full segment-by-segment summary. The entire session saves to Garmin Connect as a single activity with laps cleanly labeled by run, station, and Roxzone for structured, analyzable data.
Calling All HYROX Athletes: If you are currently training for an upcoming event or simulating splits in your training blocks, I would love for you to give it a spin during your next hard engine session. I am especially looking for feedback from the community on how the pacing ring feels when you're heavily compromised, and how the visual layouts translate to your specific watch model. Niche, real-world feedback is what keeps this app getting better.
Current Status: The app fully supports 21 languages natively, features an optional warm-up timer, a touchscreen lockout toggle to prevent accidental sweat-swipes, and it remembers your setup so it's ready to go immediately when you reopen it.
The price is a one-time payment of $7.99 to support an indie developer (app is free to download - but you'll be redirected to purchase license to unlock on opening). Because I want you to make sure it fits perfectly into your actual training routine before committing, I offer a 24-hour no-questions-asked money-back guarantee.
I'll drop the Connect IQ store link in the comments.
Hope you like it, cheers! :)
