Mixers no. Coinjoin solutions, yes. Joinmarket and Samourai Wallet for android.
“Mixers to me are centralized custodial services where you send someone bitcoin and they send you new bitcoin. CoinJoin is a collaborative transaction: when you have multiple people sending a transaction together to help break the probability-analysis that chain-surveillance companies do. As a result, it's a native bitcoin send transaction.”
