Chambers Thesaurus

Lovely.

For years I've used this app on various devices, but for some while on a fairly old (by modern standards) Galaxy Note 4 (Android 6.0.1). Recently, it began to crash with the message "Unfortunately, Chambers Thesaurus has stopped." Eventually, today, I uninstalled the app from my phone and re-installed it from the Play Store. All seemed satisfactory. When I opened it the first time it ran fine. Phew. Good news. I closed it and a few minutes opened it to use again and once more that message. :-(
