As of 13 August 2026, AI can choose a fitness tracker.

What to actually do

1. Use a tool built for this

   The route this page recommends

2. Do it yourself

   Second choice

   A chat interface, no skill needed, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Write down your maximum budget, phone model, main activities, whether you will wear the device overnight, and the features you actually need.
   2. Open a chatbot and paste the prompt with those details filled in, asking it to compare current UK options and mark unverified facts as unknown.
   3. Ask the chatbot to turn its result into a shortlist of no more than three models, with separate columns for phone compatibility, battery, subscriptions, returns and required features.
   4. Open the manufacturer page for each shortlisted model and check the model name, operating-system compatibility, sensors, battery information and subscription requirements against the table.
   5. Open a UK retailer page for each model and check the current price, stock, delivery terms and returns policy before treating the recommendation as affordable.
   6. Remove any model that lacks a required feature, does not work with your phone, needs an unwanted subscription or has information you cannot confirm.
   7. Buy only after comparing the final model and retailer terms, and use tracker readings as general wellness information rather than a diagnosis; contact NHS 111 or use 111.nhs.uk for urgent or worrying symptoms.

   Prompt

   Help me choose a fitness tracker available in the UK. Do not diagnose me or present any tracker reading as a medical measurement. Ask only the questions needed to narrow the choice, then compare suitable options in a table.
   
   My details:
   - Budget: [maximum amount in pounds]
   - Phone and operating system: [phone model and iOS or Android version]
   - Main goals: [for example steps, running, cycling, gym training, sleep, heart-rate trends]
   - Activities: [activities and frequency]
   - Battery preference: [minimum battery life or charging preference]
   - Size and comfort requirements: [wrist size, weight, display and overnight-wear preferences]
   - Accessibility requirements: [if any]
   - Required features: [GPS, heart-rate monitoring, notifications, contactless payments, waterproofing or other features]
   - Features I do not want: [if any]
   - Brands or subscriptions I want to avoid: [if any]
   
   For each recommendation, give the model, current UK price only if you can verify it from a current manufacturer or UK retailer page, phone compatibility, battery information, relevant sensors and features, subscription requirements, return considerations and the main reason it fits. Include links for every current fact. Mark anything you cannot verify as unknown rather than guessing. Separate general wellness features from anything that might sound medical. End with the best fit, the best lower-cost option if one exists, and the specific facts I must check before buying.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

3. Hand it to a person

   The distant third

   A person who owns the outcome does this end to end, worth it when the failure is dear.
