Item by item
Five differences that matter daily.
Storage
Both apps organize bottles by rack, row, and slot in a 3D cellar. Tannin adds depth: in a double-row wine fridge, it knows which bottle is in front and which is at the back, and "Show in cellar" takes you there. Viniou does not describe depth management. With a single row, both are equivalent.
Data entry
Viniou relies on label scanning, entry in seconds, and QR codes to stick on each bottle to identify it. Tannin has AI read the label and accepts a sentence to manage the cellar: "I drank the Mont-Redon 2019" frees up the slot and records the removal. Viniou offers an AI assistant for advice, and connectors to ChatGPT or Mistral, but does not describe plain-language cellar updates.
Value, insurance, and drinking window
At Viniou, market value and aging phases are in Premium. At Tannin, the drinking window is free; market value is in Enthusiast, with the source and date for each estimate, and a dated PDF insurance report with photos and locations. Viniou offers a cellar PDF export, but does not describe a report designed for the insurer.
Price
Viniou offers a generous free version, and its Premium plan costs €4.99 per month or €44.99 per year. Tannin is free with unlimited bottles and no time limit. Enthusiast costs €29 incl. VAT per year, paid at once, and adds AI, monthly valuation, and the insurance report. Over one year, Enthusiast is cheaper than Viniou's monthly Premium (€59.88) and its annual plan (€44.99).
Platform, languages, and data
Viniou is available as an iOS and Android app and as a web interface, in French according to its App Store listing; it offers food and wine pairings, buying advice, and a community dimension that Tannin does not have. Tannin runs in the browser, in French, English, and Spanish. Both let your data go: Viniou exports to Excel, CSV, and PDF from the free version, Tannin a full CSV at any time.
