Kelter is one app for your training, your food, and how you're doing. A plan built around your week, a food diary that knows what you trained, and a two-minute check-in each morning.

Three things, kept in step
Most of us end up with one app for running, another for the gym, another for food, and a notes page for our weight. Kelter keeps them together, so each one knows about the others.
Your plan
A plan that fits your week
Tell Kelter what you like to do and which days you have. It builds the weeks around that, and you can move or skip a session when life gets in the way.
- From a first 5K to a faster 10K or a half marathon, or no running at all
- Strength sessions built around your kit, with a balanced mix each week
- Every session laid out step by step, with nothing to work out yourself
Guided runs
A voice in your ear for every step
Press Start and Kelter talks you through the run: when to pick it up, when to float, and when you're done. Outdoors or on the treadmill.
- The speed or pace for each step, and how far is left in it
- A beep and a spoken cue before every change
- On iPhone, it keeps going with the screen locked, and can suggest a loop of the right length from your door
Your food
Food that follows your training
A food diary that is quick to keep. Your targets are worked out from you and your goal, and a day with a run in it gets more to eat.
- Scan a barcode, search, or just describe what you ate
- Calories, protein, carbs, and fat at a glance
- A meal planner, and a shopping list made from it
Your check-in
A two-minute check-in
Each morning, the few numbers you care about and how you feel. Kelter shows which way each is heading over the weeks, so one odd day on the scales doesn't matter.
- Weight, measurements, and protein: track all of them or only one
- Sleep, energy, and mood in a tap each
- A line through the daily wobble, so you can see the trend
Your progress
Progress that counts the right things
Kelter counts weeks on plan, not unbroken streaks, so a rest day or one missed session never sets you back to zero.
- Distance, runs, and strength sessions against what was planned
- Milestones as you reach them: your longest run, your first 100 km
- Charts for weight, measurements, and the lifts you log
Every move, drawn
Never heard of a Romanian deadlift?
Every exercise in Kelter comes with a little figure that shows the movement, and a few plain words on doing it well. There are no videos to buffer and no gym jargon to decode.
And the rest
A coach that knows your plan
Ask about your week, a niggle, or what to eat before a long run. The coach is AI, so it can make mistakes, and it says so.
Better with a friend
Share how your week is going, plan a run together, or copy a meal from each other's diary. Only ever if you both choose to.
Works with your watch
On iPhone, runs recorded on your watch arrive through Apple Health, ready to log in a tap.
On your Home Screen
Today's session and your check-in in a widget, and a run in progress on your Lock Screen.
Fine without signal
Log a run, a meal, or a check-in with no connection. Kelter catches up when you're back in range.
Only what you want
Just here for the food diary, or only the training plan? Switch off the parts you don't use and they disappear.
kelter
noun, British, an older spelling of kilter
