Fitness apps are turning steps into vouchers and discounts, and a government pilot is testing whether financial incentives boost activity \u2014 but experts warn that users trade behavioural and location data that can be re\u2011identified, raising questions over governance and who really benefits.<\/p>\n<\/div>\n
Getting your steps in can pay off in more ways than one. The NHS says even a brisk ten\u2011minute walk counts towards the Chief Medical Officer\u2019s guidance of 150 minutes of moderate activity a week and brings benefits for heart health, weight management and mental wellbeing. Alongside those established health gains, a growing number of smartphone apps now turn everyday activity into tangible rewards \u2014 coffee, discounts or vouchers \u2014 promising to nudge people towards moving a little more each day. <\/p>\n
The idea has caught institutional attention: ministers are reviewing the results of a government pilot that tested whether app\u2011based financial incentives change diet and activity. In the Wolverhampton trial participants were given fitness trackers, completed personalised challenges aligned to official guidance and earned points redeemable in an in\u2011app store for supermarket vouchers, cinema tickets and local leisure offers \u2014 while controls on what vouchers could buy (for example, excluding tobacco and gambling) were built into the scheme. The Department of Health and Social Care is now analysing those outcomes to decide whether such incentives should be rolled out more widely. <\/p>\n
Independent testing of a handful of the most prominent apps shows the offers and trade\u2011offs vary widely. Some programmes are local and immediate, designed to funnel footfall to small businesses; others are national marketplaces whose bargains tend to be promotional offers or trials rather than instant freebies. All, however, require users to trade some personal data for those perks. <\/p>\n
Paace is built around a simple proposition: convert steps into points that can be redeemed with nearby caf\u00e9s and independent retailers. The company highlights integration with Apple Health, Google Fit and Strava, social features such as leagues, and a map of partner businesses \u2014 largely concentrated in London \u2014 that say the app drives new customers. Paace\u2019s marketplace is geared to immediate, small discounts; users redeem points in\u2011app to unlock a voucher that must typically be used within a short window. Paace also promotes employer subscriptions intended to boost staff activity and bring customers into partner outlets. <\/p>\n
Local traders interviewed by the Guardian reported an uptick in footfall. \u201cI liked the idea of getting people moving. For me, that\u2019s always something to encourage,\u201d Jack Blackwell, owner of Debbie Jo bakery in west London, told The Guardian, adding that the app had introduced a younger, more active audience to his shop. Paace\u2019s pitch to independents is clear: customise offers to shift trade into quieter periods and acquire new customers \u2014 but the benefit for users depends on how quickly points accumulate and whether partners near them participate. <\/p>\n
Sweatcoin takes a different approach, converting recorded movement into a digital currency that can be spent in an in\u2011app marketplace. Many of the deals are promotional \u2014 free trials, postage\u2011only products or discounts on subscriptions \u2014 rather than straightforward, no\u2011strings rewards. The app also offers premium tiers that increase earning rates and a separate blockchain token for users who opt in. Sweatcoin\u2019s privacy documentation makes clear the types of data it collects: users must verify a mobile number and provide an email, and the app may record device and location data, contact lists, photographs and payment details, while also tracking step counts and usage metrics. <\/p>\n
BetterPoints targets active travel and community programmes by working through local authorities and employers: in funded areas users can earn points for walking, cycling, public transport journeys and even recycling or gym attendances, redeemable for vouchers or donations to charity. However, the platform\u2019s support documentation stresses that where a council or employer has not commissioned a funded challenge the app will still track activity but will not award redeemable points \u2014 a limitation that means the rewards are only accessible where the scheme has been locally commissioned. <\/p>\n
All of these systems rest on a familiar trade\u2011off between convenience and privacy. Dr Maryam Mehrnezhad, reader in information security at Royal Holloway, University of London, told The Guardian: \u201cThese companies may use [your data] for targeted ads\u2026 they can also sell large amounts of potentially anonymised data to other companies. This helps those companies understand big trends.\u201d She warned that purportedly anonymised traces of movement can often be re\u2011identified \u2014 a risk borne out by academic research showing high re\u2011identification rates in de\u2011identified wearable and sensor datasets. A systematic review published in Lancet Digital Health found correct identification rates typically between about 86% and 100% in examined studies, and the authors urged stronger technical and governance safeguards to reduce risk. <\/p>\n
Practical steps can reduce exposure without abandoning activity trackers entirely. Security experts recommend adjusting app permissions \u2014 for example, limiting location access to \u201conly while using the app\u201d \u2014 and reviewing what personal fields the app requests at sign\u2011up. That will, however, sometimes blunt an app\u2019s functionality; Paace and platforms that rely on local offers often work best with background location enabled. Users should weigh how much value they place on a free coffee or discount against the commercial uses of behavioural and location data, and check privacy policies for details on data sharing and retention. <\/p>\n
For people who want rewards but prefer a different balance of risk and benefit, there are alternative models. Health\u2011insurer programmes award points across everyday activities that unlock established retail and leisure discounts, while some retailers run loyalty systems that combine spending with activity tracking to turn exercise into store credit. These schemes vary in transparency and reach, and often require connection between insurer or retailer accounts and a phone or tracker. <\/p>\n
Ultimately, the apps offer a low\u2011cost way to nudge movement for some users and new marketing channels for some businesses. But policymakers and commissioners considering wider use of financial incentives will need to balance the short\u2011term behavioural gains seen in pilots with the longer\u2011term questions about data governance, re\u2011identification risk and equitable access. The technology can amplify small, positive changes in daily activity \u2014 provided users understand what they are exchanging for those perks. <\/p>\n
