TL;DR While you will need a VIP subscription to enjoy the best mods PlatinMods has to offer, this is still one of the best providers for free and paid hacks and mods especially for Android, but also for iOS. Generally recommended.
PlatinMods.com offers different tiers of mods ranging from free ones posted by random users to free ones by approved modders and finally the premium tier is the free and paid mods by the PlatinMods team. As far as I can tell PlatinMods are not using any spammy marketing methods or fake reviews, which is a breath of fresh air in this industry. While I have not ever used their VIP premium subscription, I am quite confident in recommending it anyways, since I have tried some of the free mods provided on the site and they have served me quite well. One should still be careful when downloading random mods from the section where unapproved modders can post, but I guess beggars can’t be choosers. As far as mobile game mod sources go, this is about as good as it gets as far as I can tell. The PM site has not been around long, but seems to be doing great so overall it gets a recommendation. As for if the VIP is worth the money, you will have to determine that for yourself.
