Built for people who train.
Hylete is a free fitness training tracker for iPhone with a read-only web companion. Log fast, see your progress clearly, and keep owning your data.
Our background
Hylete started from a simple frustration: most workout apps either drown you in clutter or lock your own training history behind subscriptions, trackers, and exports that never quite work. We wanted the opposite — a quiet tool that gets out of the way between sets and tells an honest story about your progress over months and years.
So logging lives where it should: on your iPhone, in the gym, in seconds. Strength work is reps, weight, rest time, and notes; cardio is duration and distance with optional heart rate and calories. Every exercise entry builds personal bests, progression charts, and per-exercise history automatically, so seeing that you are improving never takes extra effort.
The web app is a deliberate companion, not a second place to type workouts. It keeps your history readable from anywhere: dashboard, exercise history and charts, weigh-ins with optional progress photos, goals with timers, and one-click bulk export of everything. If you logged it, you can read it and take it with you. If you didn't log it, we don't have it.
Privacy is structural, not a promise in a popup. There are no advertising trackers or third-party cookies, your data is never sold or shared, and the infrastructure is kept small on purpose: hosting, database sync, and the transactional emails you ask for. Storing extra data would only cost us money, so we don't. Our optional Coach reviews are entirely opt-in and off by default, and you can export everything — every set, every weigh-in, every photo — whenever you like.
Hylete is an independent, iPhone-first project. We are keeping the core tracker free while we grow, and the only things we plan to charge for are the things that directly cost us: AI reviews and tools for coaches who program training for their clients. That keeps incentives aligned — we succeed when your training succeeds, not when your attention is sold. Until then, every decision favours the lifter logging today over hypothetical revenue tomorrow, and the free tracker stays free.
Frequently asked questions
Short answers to the questions we hear most.
Is Hylete really free?
Yes. Logging, history, charts, weigh-ins, goals, reminders, and full data export are free. Hylete is cheap to run at our current scale, so there is no paywall on the core tracker and no ads or data-selling to work around. We intend to keep it free forever.
How does it make money?
It doesn't yet — by design. The app is inexpensive to run until user numbers grow significantly (thousands). In the future we plan to charge for exactly two things that cost us money: AI Coach reviews (model inference isn't free) and tools for coaches who run their clients' training calendars. Individual training tracking stays free.
Why iOS only?
Focus. Hylete is an independent project and the iPhone is where logging happens — in the gym, between sets. Doing one client well beats doing three badly. The web companion keeps your history readable anywhere, and you can export everything at any time, so your data is never trapped on one platform.
We'll consider adding an Android app in the future. For now, we'll ensure our web companion works well on all devices and is an installable Progressive Web App (PWA). You can find out more about PWA's here.
What is your AI policy?
All AI features (called Coach) are entirely opt-in and off by default. No training data is ever sent to AI models without your express consent. If you opt in, your data goes to Cloudflare Workers AI solely to generate your weekly review — never for advertising, never sold or shared. You can opt out at any time, which stops all future AI processing. Past reviews stay visible unless you delete your account from your Profile page, which removes them along with everything else. Read the full detail on the privacy page.
How safe is my data?
We store only what the app needs to work — your account, exercise entries, weigh-ins, photos, goals, and reminder preferences — and never sell or share it. There are no ads, trackers, or third-party cookies. Anything that sends data anywhere else is opt-in: Coach AI reviews and weight reminder emails are both off by default and stop the moment you switch them off. And everything stays yours to take with you: the Data Export page downloads every exercise entry and weigh-in, photos included, at any time. Read the full detail on the privacy page.
How can I download the app?
For now we're in public beta so the app is not available in the App Store. If you sign up for an account you will find a link inside that allows you to register your device and download the app. All features are available in the public beta.
