★★★★★ paid for subscription yet doesn't work.
★★★★★ I can't imagine renewing my subscription unless lag-time gets fixed.
★★★★★ Why am I paying so much per year when 97% of content does not change? Im happy to pay once. Not every year. Shove it Sanford and son
Worse after an update26%

10 of the 1 and 2 star reviews.

★★★★★ The search function takes ages to search, and ever since I performed the most recent update, the app is essentially unusable.
★★★★★ They just disclaim that newer data is available with update.
★★★★★ I bought the app for 29.99, with the understanding that you have the option to update yearly (as has been the case previously from personal experience).
Crashes and freezes23%

9 of the 1 and 2 star reviews.

★★★★★ Freezes on the main screen and doesn't allow me to click anything.
★★★★★ Please tell your profit-mongers to stop locking-down the app on its expiration date, and let access continue, before they find themselves on vacation, bitten by a Komodo dragon, needing to look up broad spectrum…

Wrong or poor results10%

4 of the 1 and 2 star reviews.

★★★★★ This app wasn't useful once during 12 months, then it auto renews the subscription. Stay away from it, ultra low yield info & bad design.
★★★★★ New update a few days ago makes it so I cannot use the app at all. Every time I try to open it, it crashes. Hope this is patched soon. Unacceptable.
★★★★★ When I open the app, it just sits on “checking subscription” forever and doesn't let me do anything.
Lost data, sync, backup8%

3 of the 1 and 2 star reviews.

★★★★★ After 1 year, I chose not to renew the subscription knowing I would just have the older reference, only to find that I completely lost the whole reference.
