Kettle is an AI coach you can actually talk to. Log sets, start workouts, surface PRs, and plan sessions — all through a conversation that understands your full training history.
Log sets, start workouts, or plan sessions through natural conversation that knows your history.
Volume, PRs, and streaks update as you train. Know when to push and when to recover.
Resume where you left off. Kettle tracks rest times, sets, and exercises across every workout.
Weight, reps, rest — with smart defaults. Spend less time tapping forms, more time training.
Hit a personal best? Kettle calls it out the moment you log the set. No spreadsheets needed.
No forms. No menus. No data entry. Just say what you did and Kettle keeps the record.
Generic AIs guess. Kettle pulls from a curated library of fitness research — every answer cites the studies behind it, so you train on evidence, not vibes.
Protein dosing, training frequency, periodization — backed by Morton 2018, ISSN, and IOC reviews.
Mifflin-St Jeor, deficit ranges, and what the literature actually says about nutrient timing.
Frequency vs. volume, compound vs. isolation, and progressive overload that's actually progressive.
DOMS, deload protocols, and sleep architecture's measured effect on adaptation.
Pregnancy, postpartum, masters athletes — programmed against ACSM and WHO guidelines.
HIIT vs. steady state, the concurrent training effect, and how to stack both without losing gains.
Ask Kettle "how much protein do I need?" and you don't get a confident guess. You get the 1.6–2.2 g/kg threshold from Morton's 2018 meta-analysis (n=1,863) — with the citation, the confidence interval, and the population it applies to.
I lose interest in the other apps where you have to keep manually adding your sets. I can just type my workouts in as I'm going along and the AI tracks everything for me and presents it nicely! Way faster workflow!
After a busy day the last thing you want to have to do is try and plan your workout. This app not only takes the decision burden out the way but is able to tailor workouts to your exact needs and goals. Highly recommend.
Unlike other tracking apps I've used, the AI chat feature helps me ask questions during my workout and it actually links the science research papers at the same time.
It's simple to use and the AI feature helps a lot to get things done. I can add workouts easily.
Such an easy app to use and love the chat functionality. Been using it for a while and it's making my workout so much more efficient.
It's a very good app to track your workout, and the AI system assists with making planning your workouts while providing valuable information when needed.
This is a great app, very helpful — I'm loving it.
