    Where this fits in your plan

    What you are actually buying

    Apps, wearables and digital programmes. Some are free with an optional paid tier, some are annual subscriptions, and one or two need hardware. They run on your own phone or device, and the data stays in the provider's account, not in your Take a Seat record.

    How tools pricing works

    Prices are the UK consumer rate at the time of review. Free tiers are genuinely usable in most cases, and the paid tier normally unlocks history, export or coaching rather than the core function, so start free where a free tier exists. Hardware costs are listed separately from any ongoing subscription. The figure on this page, Free via NHS / £200 private, follows the same rule.

    Who this suits, and who it does not

    Best suited to self-monitoring and habit work between appointments: tracking mood, sleep, medication response or symptoms across weeks so patterns become visible. They are a poor substitute for assessment or treatment, and a tracker that raises your anxiety rather than lowering it is the wrong tool for you.

    What happens after you click through

    Download or order direct from the provider. If you are working with a specialist, look for an export function on day one, a few weeks of your own data is one of the most useful things you can bring to a first consultation.

    Prices and inclusions are checked at review and change without notice, always confirm on the provider's own page. Nothing here is a diagnosis or a treatment recommendation, if you want one, speak to a specialist or build a pathway.
