Now taking early enquiries.
Re-branded
The same app, in your colours.
Here's 3Lite as it is, and the same screen re-branded for an example trainer, Northline Coaching: new colours, a new logo, their own photos.


What you get
Everything your clients need, under your name.
Most coaching apps make you fit their brand. 3Lite fits yours, and gives your clients a complete training, food and recovery app from day one.
- Your logo, colours and photos
- From the home-screen icon to every screen, your clients see your brand, not ours.
- Only the features you want
- Switch off anything that doesn't fit your coaching, such as Enhancements or Community, so the app feels made for your clients.
- One place to manage clients
- See who's training, who's checked in and who needs a nudge, without chasing messages and spreadsheets.
- Everything 3Lite already does
- All three pillars: a food diary on UK food data, programmes and workout logging, sleep and injuries, plus progress photos, weekly check-ins and offline logging.
- One monthly price
- Your branded app, set up and kept up to date, for one monthly cost agreed with you up front. No per-feature extras.
- Your clients' privacy built in
- Health records stay protected under UK GDPR, and your clients will always know what you can see.

FAQ
Questions from trainers
Is the trainer version available now?
It's in development. Get in touch and we'll talk through your set-up, what you need and timings, and keep you updated as it's ready.
How much does it cost?
One monthly price, agreed with you before anything starts. It depends on your set-up, so email us for a quote.
Can I remove features I don't use?
Yes. Choose the parts of 3Lite you want your clients to see and switch off the rest, for example Enhancements, Community or cycle tracking.
Will my clients see the 3Lite name?
Your app carries your logo, colours and photos. Legal pages will say who runs the service behind it.
Can I see my clients' data?
The trainer view is designed to show you what you need to coach, such as sessions, check-ins and consistency. Clients will always know what you can see.
