Log every visit, rate every drink, and build a record of cafés and experiences that matter to you – all in a beautifully designed, private app that lives on your device. Log Every Visit Record where you went, what you ordered, and how it was. Full drink customization covers type, temperature, milk base, syrups, cold foam, and size – so your log actually reflects what you drank. Rate What Matters Score each visit across multiple criteria: coffee quality, atmosphere, value, service, and more. A composite score gives you an at-a-glance view of how a café stacks up, while individual criteria reveal exactly why you loved — or didn't love — a visit.
