Your muscles light up when you train them. Now you can watch it happen.
ATHENA is a workout tracker built around one idea: you should be able to SEE your training. Log your sets and a full-body avatar lights up, muscle by muscle — 23 separate regions, from upper chest down to tibialis. Train hard all week and the whole figure glows. Skip legs and, well, you'll know.
THE AVATAR
• 23 individually tracked muscle regions, front and back
• Weekly targets that adapt to YOUR training — a full glow means a great week for you, not for some pro bodybuilder
• Tap any muscle to see exactly how many sets it got
• Keep your streak alive and the avatar earns a living energy aura
• 6 color themes that restyle the entire app, avatar included
FAST, SERIOUS LOGGING
• Set-by-set logging with your previous numbers right where you need them
• Automatic PR detection, supersets, warm-up and drop sets, RPE
• Per-exercise rest timers and a plate calculator

BUILT INTO YOUR IPHONE
• Full lock screen Live Activity: rest countdown and Complete Set without unlocking your phone
• Live heart rate during workouts with AirPods
• Workouts save to Apple Health and count toward your Activity rings
KNOW YOUR NUMBERS
• All-time stats: volume trends, consistency heatmap, your Big 3, most performed lifts
• Strength, estimated 1RM and volume charts for every single exercise

I’ve been using Athena to keep track of my workouts and I really like it. It’s simple, easy to use, and doesn’t make tracking everything feel like a chore. I like being able to look back and see what I’ve done and how I’m progressing. It’s definitely helped me stay more consistent at the gym. I’d recommend it to anyone who wants an easy way to keep track of their workouts
Developer Response
“Helped me stay more consistent” is the whole reason ATHENA exists — that line made my day. Thanks for the support, and keep that streak alive 💪
Honest review
L-laven
Interesting app with unique physique tracking and competition with friends feature. Can get lost in the app a bit but after a few minutes, understood it. I love that the app syncs with my Apple Watch so I’m not constantly manually tracking. Highlights on my muscle tracker is crazy addicting. I can visually see what I lack and what I don’t lack, then seeing everything glow feels good knowing I hit a crazy workout. Been working out for 3 years and using other workout apps to track my sets, but this one was simple at most. Amazing app, can’t wait to see more features in the future like different avatars!
Developer Response
This might be my favorite review yet — honest feedback from someone who's actually put in years and tried the other apps means everything to a solo dev. You're right about getting lost at first; smoothing out those first few minutes is high on my list. And “different avatars”… you're reading my roadmap 👀 More is coming for the avatar than I can fit in this reply. Thanks for giving it a real shot — reviews like this genuinely shape what gets built next.
Great platform for tracking and planning

I am very happy with downloading the app. It is a strong tool that I can track my progress, plan exercises and compare with friends. It’s a great app and I cannot wait for future updates to further my progression. Would recommend to my fitness friends and whoever is looking to improve themselves.
Developer Response
Tracking, planning, and beating your friends — you've found all three pillars. A lot more is coming for the compare-with-friends side very soon. Appreciate you being here early 💪
Best App Ever
Andres727
This app saved my life, before I was an absolute CHUD no goals, money, aura. I had nothing but then I found ATHENA and my life instantly improved now I’m on my way to becoming an absolute CHAD, with this app there is no one or anything that can stop me.
Developer Response
The CHUD-to-CHAD arc is the greatest transformation story ever told in an App Store review. Nothing can stop you now. Keep the aura growing 🫡
A brand-new avatar.
Every figure has been redrawn from scratch — men's and women's, front and back. Every muscle is its own panel now, the lines between them stay sharp when they light up, and a few muscles that were never separate before finally are: side delts, adductors, abductors, tibialis.
Your training data doesn't change. Your body just looks the part.
That's the whole update — so it could go out fast.
