Train
for what you
actually do.
A native iOS training app that drafts your routines — strength, mobility, cardio, and drills — logs every set on your wrist, and turns it all into stats you can actually read.
The principles
Three ideas Kilo won't compromise on.
Built for iPhone, not ported to it
Pure SwiftUI on iOS 26 and watchOS 26. It's fast, it works offline, and your data is yours — because Kilo was made for these devices, not adapted from a website.
An AI coach that writes the plan
Tell the coach your goal and it drafts the routine, adapts it to your equipment, and reads any workout link you send. You see and approve every change before it saves.
Every suggestion fits your gym
Tell Kilo what you own — at home, at the gym, on the road. Exercises and weights are picked from the equipment you actually have.
Coach
Tell it what
you want. It builds it.
Describe what you train for, the equipment you have, the days you can show up. Or paste a YouTube link to a program you like. Kilo drafts the routine, shows every change before saving, and learns from what you actually do.
Apple Watch
Log every set
from your wrist.
Leave your phone in your bag. The Apple Watch app checks off sets, runs your rest timer, tracks heart rate, and shows the next exercise — then syncs the whole session back the moment you finish.
Sharing
Import a routine. It fits your gear.
Tap a routine someone shared and Kilo adapts every exercise to the equipment you actually have — on device, before anything saves. Each move is matched, swapped, or added, and nothing lands in your library until you approve it.
Stats
Progress you can
finally read.
Charts, comparisons, and exercise-by-exercise breakdowns built into the app — not stitched together from a CSV export.

Routines · Playbook
Your routines and your training notes, together.
Save the routines you run again and again. Write the training rules you follow — rep ranges, when to add weight, what to skip — in plain words. The coach reads both before it suggests anything, so its plans match how you actually train.
YouTube · URLs
Share any video. Get a routine.
Hit the share sheet on a YouTube video, an article, or a podcast page. The coach reads it and builds a routine.
Routine
Push Day · 6 exercises
Exercises
Hundreds of exercises.
Strength, calisthenics, and mobility — grouped by movement and searchable. The coach can add new ones too.
Equipment
Profiles per gym.
Home, commercial, hotel — Kilo adapts.
History
Every workout, kept.
A full history of what you lifted — not a timer you reset and forget.
HealthKit
Reads activity.
Writes workouts.
Native two-way sync with Apple Health. Steps in, sessions out.
Sync
One account.
Every device.
Routines, history, and equipment follow you to every iPhone and Apple Watch you sign into.
MCP · OAuth 2.1
Let ChatGPT build
your next workout.
Or Claude. Or both.
Kilo is an MCP server. Connect it inside ChatGPT or Claude in two taps and let either assistant create exercises, search your catalogue, and build routines straight into your library. OAuth handles the rest.
Available with Kilo Pro

Not another fitness app. An opinion.
iOS-only on purpose.
No web app, no Android, no compromises. Every screen and every gesture is built for the device that holds it.
Coaching you can audit.
Every tool call is named and shown before it touches your library. You approve it, it runs. You don't, it doesn't.
Built by someone who trains.
Not a feature factory. Every screen exists because it was missing from the apps the maker actually used.
