I only use android, so I don’t know about iOS deals, but I will check them out as well for comparison sake:
Currently there are two I see that interest me, these both come with the premium purchase in-game packs that you would otherwise have to buy from the free versions:
Mystic Guardian VIP: Old School Action RPG (normally $3.99 USD)
(This deal ends in 1 day according to my mobile phone, so I am not sure how long it will last.)
The only version I can find on the iOS store is the free version, so you might not be out of luck. I cannot check, sorry.
and
Timing Hero VIP: Retro Fighting Action RPG (normally 3.99 USD)
(This deal ends in 6 days according to my phone.)
Same as above, I can only find the free version of this game on the iOS store.
The VIP(Paid) versions still say “in-app purchases” so I am not exactly sure what that entails. I have not tried the games myself, but since one of them ends in 1 day, I thought I would try to share ASAP.
If you have played one or both of these games, feel free to educate us on what we should know. 
Otherwise, happy gaming everyone!
