AS Mode, How HAVYT Adapts to Ankylosing Spondylitis

Most fitness apps assume you wake up every morning ready to train. For people living with ankylosing spondylitis that assumption is not just wrong, it works against you. HAVYT AS Mode was built from the ground up to support people whose bodies do not follow a predictable schedule.

What is AS Mode

AS Mode is a chronic condition support feature inside HAVYT that changes how the entire app responds. When activated, training and recovery suggestions use the signals you choose to log about how your body feels each day.

It is not a separate app or a bolt-on feature. AS Mode rewires the core logic of HAVYT so that every decision the AI makes takes your condition into account. The result is a fitness system that adapts to you instead of expecting you to adapt to it.

How the daily wellness check works

Every morning AS Mode presents a quick wellness check covering six key signals: sleep quality, pain levels, energy, stress, stiffness duration and overall mood. It takes less than sixty seconds to complete.

Based on your responses, the AI calculates a daily wellness score. This score is not a diagnosis or medical metric. It is a personal baseline tracker that helps you and HAVYT understand how your body is doing today relative to your own patterns.

On days that look similar to your usual baseline, HAVYT can leave the plan as it is. On difficult days it can suggest a gentler version and explain which check-in signals informed that suggestion.

Automatic plan adjustment

This is where AS Mode does something most training apps do not. When your wellness score indicates a difficult day, HAVYT does not just tell you to rest. It recalibrates.

  • Training can scale down based on your signals, with lower volume, supported variants or gentle mobility offered as reversible options
  • Food logging stays simple so you can optionally notice personal food-to-symptom patterns without calorie or macro targets
  • Recovery gets a clearer next step , such as a lighter session or extra rest, with the check-in signals behind the suggestion shown

HAVYT keeps the decision light on difficult days, but it never takes control away from you. Suggestions are conservative, explained, and easy to accept, change or skip. They are wellness guidance, not medical instructions.

Pattern recognition over time

One of the most powerful aspects of AS Mode is what happens over weeks and months of daily tracking. The AI begins to surface patterns that are invisible in the moment.

You might notice that higher-symptom days sometimes follow a combination of poor sleep and heavier training, or that certain weather patterns appear alongside increased stiffness. These are personal correlations worth watching, not causes or predictions.

These insights are personal to you. AS affects everyone differently and generic advice rarely applies. By tracking your own signals consistently, you build a personal dataset that reveals how your body specifically responds to different inputs.

This data can also be valuable when speaking with your rheumatologist or physiotherapist. Instead of trying to remember how the last few weeks felt, you can show them concrete trends and patterns.

What AS Mode does not do

AS Mode is a fitness and wellness support tool. It is not a medical device and it does not provide medical advice, diagnosis or treatment. The wellness score is a personal tracking metric, not a clinical measurement.

HAVYT encourages users to work closely with their healthcare team. The patterns and data AS Mode surfaces are designed to complement professional medical care, not replace it.

Who is AS Mode for

AS Mode was originally designed for people with ankylosing spondylitis, but the underlying system is built for anyone managing a chronic inflammatory condition that affects their ability to train consistently. People with fibromyalgia, lupus, rheumatoid arthritis, IBD and similar conditions may find the same structure useful.

If your body has good days and bad days and you need a fitness system that understands the difference, AS Mode was built for you.

How to activate AS Mode

AS Mode can be activated during onboarding when you first set up HAVYT, or at any time from your profile settings. Once activated, the daily wellness check becomes available and HAVYT can start tailoring suggestions as you build a personal baseline.

There is no additional cost. AS Mode is included for every HAVYT user because we believe that supporting people with chronic conditions should never be a paid add-on. See AS Mode.
