Your licence key arrives by email straight away.
Built for shopping trips. Scan, read the colour, move on.
Looks the product up in a free database of UK supermarket products and matches it to the closest lab-tested food.
See the purines in the whole pack and in the portion you actually eat – and change either amount.
Add the foods that set you off. Purine Smart flags them in red whenever they turn up – even in the ingredients.
Warnings for alcohol, sugary drinks, high salt and hidden high-purine ingredients like yeast extract.
Add what you eat and keep a running total against a daily guide you can set yourself.
