Disappointed that voice pronunciation is unable to use in phone muted mode.
Regret Purchaser
Very disappointed that the voice pronunciation cannot function when the phone is in “mute” mode. At my work place, phone has to be put on “silent” mode, strictly as required within our work environment. Thus, your app will not be of use to me, if it cannot function in this situation. Would appreciate if you could enhance this feature to enable voice pronunciation to function when phone is in “mute or silent ” mode, as what other dictionaries’ apps could do. Hope you can provide this feature to your users.
Don’t buy.

Please don’t buy this app. I never know that I bought a dictionary app and can only check up on one word a day unless I have to pay for a subscription. I might as well buy a physical book dictionary. Further, the speaking function has been disabled with the new updates unless you buy their subscriptions. Might as well use Google translation app. It’s free and has a speaking capability to use in conjunction with an online dictionary. Same on you! Oxford English Dictionary. Note: Dear Mary-Ann (developer), thank you for your reply. As mentioned in the very first and second statement of my review. I used my hard-earned money to PAY for the app. NOT using the FREE version. Had I known this would happen, I will NOT BUY. Thank you.
