360° Body Progress

The mirror lies after one session.
Your timeline does not.

Periodic 360° scans build a visual record of how your physique actually shifts over weeks and months. Not a generic avatar. Your body, from every angle, stored and compared over time.

This is the feature no spreadsheet can touch. Progress you can spin, scrub, and share.

Share & Compare

Progress is better 1v1.

Pick a friend. Same day. Side by side. Overview stats, workouts, diet, and dual 360 turntables facing each other like a real rivalry should feel.

Share your journey without posting to a feed. Compare with people who actually care about your reps.

Muscle Overlay

Muscles light up on your body.

During and after every workout, see exactly which muscles you trained painted directly on your own scan. Not a stock anatomy diagram. Your shoulders. Your quads. Your progress map.

You finally know what that session actually hit.

Gamified Fitness OS

Every rep counts.
Even when the mirror stays quiet.

Gains are invisible after a single gym visit. That is why motivation dies. Nostia Fitness turns training, steps, and consistency into XP you can see filling your level bar today.

Level yourself up. The game layer exists for one reason: keep you showing up when results are still brewing under the surface.

Train & Fuel

Solid logging under the hood.

Workouts and diet are not the headline, but they are built properly. Log sets with weight and RIR, track macros against your daily targets, and let that real data feed XP, compare, and calorie estimates.

Hundreds of apps log food and reps. We connect that input to everything else you see on this page.

Real Science, Game Layer

Not a fake RPG.
Gamification meets science.

You do not level up because we slapped a big number on screen. XP comes from validated training and nutrition inputs: intensity, load, adherence, and consistency.

The game layer keeps you hooked. The science layer keeps it honest. Progress you can trust, wrapped in motivation you can feel today.

TDEE

Daily energy targets

Your calorie goal is shaped around cut, bulk, or recomp. Diet XP rewards how close you land to that real target, not vanity streaks.

RIR

Reps in reserve

Log how many reps you had left in the tank. RIR captures true set intensity better than rep count alone and drives how hard each set scores.

Effective load

Load relative to your max

A set at 80% of your estimated 1RM is harder work than the same weight when you are weaker. XP scales with that ratio so effort matches reward.

Epley formula

Estimated 1RM from every set

Strength trends, peer comparison, and anticheat all run on Epley-based 1RM estimates. Fantasy numbers do not survive contact with your training history.

kcal burn

Session calorie estimation

Workout burn uses MET baselines, muscle groups trained, session duration, and fatigue. A real estimate tied to what you actually did, not a random badge.

XP engine

Motivation without fiction

Walking, workouts, and diet each feed capped daily XP budgets. You see the level bar move because the inputs underneath are real.

Under the XP bar

What actually moves your level?

Train

Set XP from RIR, effective load, and your Epley 1RM. Harder honest sets score higher.

Fuel

Macro and calorie adherence against your TDEE-style daily goal. Close to target, close to full diet XP.

Track

Steps, 360 scans, strength trends, and session kcal estimates stack into one progress picture.
