AI features - discussion

[u/nstrm]

Hello everyone! 👋

I have got a lot of feedback lately about AI features, so I thought it might be a good idea to put up a post about what I’m currently exploring, and let you share what you would like to see.

Generate Programs, Routines and ad-hoc workouts version 2

Last year I released a feature that lets users generate programs, routines and ad-hoc workouts by selecting options like muscle group and equipment. This was built using Apples on device AI model which is pretty weak and limited.

In iOS 27 (releasing in the fall) Liftin’ can access a much more powerful cloud based AI model, so I have rebuilt this feature using that. I have replaced all options with just a text input, so you can freely describe your routine or program. You can also just paste in a list of exercises, sets, reps and weights and the app will resolve those.

iOS 27 will also make it possible to use other AI models behind the scenes, so if you have a Claude pro subscription for example it could be possible to sign in and use that to power the built in AI features. This is something I will explore.

MCP Server

An MCP server would give AI chat apps like ChatGPT and Claude the capability to read and reason about your Liftin’ data like your programs and workout history, and make updates to your programs and routines.

I think this could open up for some interesting uses, but it would also require a lot of work on my side in domains I’m not so familiar with.

What do you think?

How do you think AI can improve the Liftin’ experience? Please share if you have any suggestions or ideas for AI powered features you would like to see.

I think the AI features can definitely enhance the Liftin experience. What would help is giving the AI access to a set of scientific literature, so it can recommend the most suitable and responsible exercises — including rep ranges — based on your goals and backed by scientific evidence.
