You train alone.
You don't improve alone.

Aria is the AI training companion built for sprinters who train solo. Sprint analysis, adaptive programming, recovery, nutrition, rehab, and mental readiness — one app that learns and evolves with you.

The Problem

Training alone shouldn't mean training blind.

Most solo sprinters are guessing. No second set of eyes, no structured feedback loop, no one managing the full picture. The result? Wasted sessions, hidden weaknesses, and preventable injuries.

No eyes on your mechanics

You can't watch yourself sprint. Without real-time form feedback, bad habits compound silently — costing you tenths you'll never get back.

No plan that adapts to you

Static PDFs and cookie-cutter programs don't know your recovery status, competition schedule, or whether yesterday's session was too much.

No one managing the full picture

Training, nutrition, recovery, rehab, mental readiness — solo athletes juggle all of it alone. Drop one ball and performance suffers. Or worse, you get injured.

Two AI Engines. One System.

Aria doesn't just analyze. It thinks in two layers.

Aria IQ reads your body. AI Coach tells you what to do about it. Together, they replace the coaching team you don't have.

Aria IQ

The Sensing Layer — What is my body doing today?

Recovery is excellent

Readiness 100/100 — Resting HR trending down 3%

Rapid weight loss flag

1.3 kg dropped in 7 days during comp prep — monitor energy

55 Days to Iberoamericano

Competition countdown active — goal: 10.00s in the 100m

Protein intake solid

180g at 92.3 kg = ~1.95 g/kg — meeting sprint needs

AI Coach Insights

The Action Layer — What should I do about it?

Schedule quality speed work

Add 3x30m block starts at 95-100% plus 3x60m at 95%

Adjust calories for cut

200-300 kcal deficit on non-intense days — protect recovery

Race prep timeline

Max-speed test in 3-4 weeks, then 10-14 day taper

Convert strength to power

Contrast training: heavy squat @85% → 3x15m sled pushes

Everything You Need

One app. Every dimension of sprint performance.

Training, nutrition, recovery, rehab, analytics, and coaching — unified and intelligent. No hardware required.

Weather Performance Engine

Know before you go. Should you push hard today?

Aria converts your local weather into a Sprint Score (0–100) and tells you exactly what kind of session to run. Not just temperature — wind direction relative to your sprint lane, heat load risk, UV index, and a full AI session recommendation.

  • Sprint Score 0–100: how good today is for top performance
  • Wind intelligence: tailwind, headwind, and crosswind detection
  • Heat Load Risk: Low / Moderate / High / Extreme protection
  • Best session types for today's exact conditions
  • Apple Watch alert: "Excellent conditions — push hard today"

Heat Load: Low Tailwind Assist Clear Skies

Excellent for Max Velocity. Tailwind assists top speed. Schedule acceleration + flying 30s today — avoid peak UV between 12–2 pm.

Recovery, Rehab & Injury Prevention

See injury risk coming. Before it arrives.

Aria monitors your training load, movement patterns, and recovery signals to flag elevated injury risk before symptoms appear. Pair that with a dedicated rehabilitation hub organized by injury type — and you have a system that keeps you healthy and training.

  • Proactive injury risk detection from workload and recovery data
  • Training load monitoring: safe range vs overload alerts
  • Rehab programs by area: Acute Muscle, Chronic, Back, Bone Fractures
  • Ask Aria about your injury for personalized protocol guidance
  • Health Trends: sleep, resting HR, and weight over time

Cycle Tracking — Built for Female Athletes

Her body. Her phases. Her edge.

Aria is one of the only sprint training apps that integrates menstrual cycle tracking directly into training and nutrition recommendations. Because female athletes deserve programming that adapts to their biology — not ignores it.

  • Phase-aware training adjustments (Menstrual, Follicular, Ovulation, Luteal)
  • AI recommendations adapt intensity, volume, and recovery to each phase
  • Nutrition guidance shifts with your cycle — macros, hydration, and micronutrients
  • Daily logging: energy, pain, mood, bloating, flow, and cramps
  • Cycle ring visualization with phase indicators and day tracking

Mental Wellness — Mind Tab

  • Talk to Aria about stress, mindset, and mental readiness
  • Stress Management: techniques for training and competition pressure
  • Sleep & Recovery: optimise sleep for peak athletic performance
  • Pre-Race Anxiety: strategies to manage nerves before a race
