Works like a charm and fast support ### 1/5 — Didn’t get full access to data after purchasing the data *2025-03-08* I was prompted to make a one time purchase of 2025 data to get full access. I did the purchase directly on the app through Apple Pay and after the purchase was successful I still didn’t get the full data. The app is still asking me to purchase the data to see all the information for 2025 calendar ### 2/5 — Good app, confusing purchase *2025-01-20, version 1.5.6* I love this app and I feel it does give accurate info on the best times to taste wine, but I am confused if I need to buy the app yearly or if it was a one time purchase? I purchased it last year and in the menu it said “one time purchase” but it is asking me to purchase again. Thanks! ### 1/5 — Paid but not working *2024-12-17, version 1.5.6* In less than 12 months I have paid twice and can still not access the future data?!?! ### 1/5 — Una fregatura *2024-11-17, version 1.5.6* Ho pagato l’abbonamento ma non è stato attivato. Non c’è modo di comunicare. State alla larga dai truffatori!!!! ### 5/5 — Top *2024-11-14* Top que dire de plus ! ### 1/5 — Timo *2024-10-30, version 1.5.6* He pagado por la versión completa y no puedo ver los días futuros tampoco. ### 1/5 — Обман *2024-10-24* Оплатила, но ничего не работает((( обманули ### 1/5 — 11 *2024-09-21* 怎么变啊 ### 5/5 — 怎么变 *2024-08-11* 怎么变 ## Frequently asked questions about When Wine Tastes Best ### What does the When Wine Tastes Best app do?
