Start session

Most people run four or five apps for training, food, sleep and recovery, then try to make sense of it on their own. Aspier is one app that does the joining up for you.

What it does

One app. Every session, every meal, every night's sleep.

Training plans that fit your week

Strength, running, Hyrox and mobility. You say which days you have and how long. Every set, rep, load and pace is worked out in code from rules a trainer wrote.

Race prep, with a date on it

Give it a race date and the plan works back from it. Build, sharpen, taper. Hard days and long runs are spaced the way a coach would space them.

Meal plans and a shopping list

A week of meals that fit your training days, and one shopping list sorted by aisle. Targets move with the day: more on a hard session, less on a rest day.

Photo food logging

Take a photo of the plate. You get an estimate of what's on it, and it tells you it's an estimate. Fix anything it got wrong in a tap.

Recovery from your watch

Sleep, heart rate and strain from Apple Health, WHOOP, Withings or Strava. You get a plain read on the day, in the words a coach would use. Never a diagnosis.

A coach you can ask

Ask why today's lighter, or what to eat before a long run. It answers from your own plan, your log and your sleep. It writes the words. It never sets the weights.

How it's built

The numbers come from rules, not from a chatbot.

Every number is computed in code

Sets, reps, loads, paces and deloads come from rules the trainer wrote. A language model never picks a weight.

The AI only writes the coaching words

It explains the session and answers your questions. That's the whole job.

You get screened first

Everyone answers a short PAR-Q based health questionnaire before a plan is built. A yes on any question means GP clearance first.

The founder

I built this for the people I train.

I'm a personal trainer in the UK. The people I coach were running four or five apps and still asking me the same three things: what do I do today, what should I eat, and why am I so tired.

Aspier puts the answers in one place, and the numbers come from the same rules I use on the floor. The app writes the words. I wrote the rules.
