Buyer Fit rates how well a product suits a specific way of using it, on the same active BluntBench methodology as its overall BluntScore, using only characteristics traced to a manufacturer, retailer or documented source. Requirements with no published data stay marked as not documented rather than scored as a pass; a non-negotiable requirement a product is documented to fail is flagged and rules it out of that use case regardless of its other strengths. Use cases are only rated when this category's research actually covers them.

How we score fitness trackers
Fitness Trackers — BluntBench v1.0
Every product in this article is scored with this single BluntBench methodology version — criteria are never mixed between categories, and when the methodology changes a new version is published rather than the old one being rewritten.
Each product's score out of 10 is a weighted result, not an impression. These are the criteria and weights used for this category — every pick below shows its per-criterion scores, and their weighted mean is the overall BluntBuys score.
This weighting is specific to fitness trackers: it uses the Fitness model, not one generic scorecard. Training performance carries the most weight (25%) because it is what decides whether fitness trackers do their job at all, followed by build & stability at 18%. Warranty & long-term ownership still counts, at 8%, but it rarely changes which option a buyer should pick. A different category is judged with different criteria and different weights, so scores are comparable inside this guide rather than across unrelated product types.
Criteria adapt to the product. A criterion that is not part of what a product does — for example a seal rating on an open bin or a Lazy Susan — is excluded from that product's breakdown and its weight is redistributed, rather than scored as a weakness. Scores therefore compare how well each option suits its intended use case; products of different types are not always direct substitutes for one another.
| Criterion | Weight |
|---|---|
| Training performance | 25% |
| Build & stability | 18% |
| Comfort & ergonomics | 18% |
| Footprint & storage | 13% |
| Tracking & features | 8% |
| Value for money | 10% |
| Warranty & long-term ownership | 8% |

Evidence required by Fitness Trackers — BluntBench v1.0
- Training performance: Manufacturer performance sheet or independent test data naming the figure and the test method.
- Build & stability: Documented materials and warranty terms, plus recurring owner-reported failures.
- Comfort & ergonomics: A documented source for the figure or characteristic being judged — never an unsourced impression.
- Footprint & storage: A documented source for the figure or characteristic being judged — never an unsourced impression.
- Tracking & features: A documented source for the figure or characteristic being judged — never an unsourced impression.
- Value for money: Current retailer price plus the manufacturer's stated consumable life, so the running cost is calculated rather than estimated.
- Warranty & long-term ownership: A documented source for the figure or characteristic being judged — never an unsourced impression.
