For 30yrs, Ive purchased Pocket Pharmacopoeia from its early days as the smallest of pocket books to its current incarnation - including many of their speciality books and apps. However, any of those I have purchased are still mine to use if I am content wit the content. NOT ANY MORE!!! As numerous others have commented, the latest update disables the app to pay for subscriptions - and this is untenable! I will no longer support this app. And whereas I used to update my pocket books each time they were available, I will no longer be doing so. Shame on Tarascon...
