Gear that actually helps

Buying guides for the kit that genuinely helps you track food, movement and health — what to look for, what to skip, and what to ignore. No brands, no prices, no affiliate links.

How these guides are written

Most gear writing exists to sell you something. This does not. There is no shop behind it, no affiliate link inside it, and no brand named anywhere in it, because we have not tested products and a recommendation we cannot stand behind is worth nothing to you. What each page gives you instead is the small number of specifications that genuinely change the result, the features that are there to be sold rather than used, and an honest description of when the cheap version is the right version — which, for most of these categories, is most of the time.

• No brands, no models. The specification that matters is described so you can recognise it on any product, in any country, in any year.
• No prices. Prices move, vary by country and go out of date the day they are written. Each guide describes a budget, a mid and a premium band by what you get for the money, not by a number.
• The cheap one is usually fine. Where that is true, the page says so plainly, and says which one category is the exception.
• It connects to your diary. Every category ends with how the thing changes what you can actually track, because a gadget that does not change a habit is just clutter.

The categories

The one category where the specification really matters

For nearly everything here, the honest advice is to buy the inexpensive version and spend the difference on nothing. Blood pressure monitors are the exception, and it is worth saying loudly: a monitor that has not been independently validated, or one with a cuff that does not fit your arm, produces confidently wrong numbers, and a wrong blood pressure reading is not harmless. If you read one guide here before buying, read that one.

Nothing here is a paid placement, an affiliate link or a tested product review. These are category guides describing what the specifications mean, so you can choose well without being sold to.
