Yes, ViaBTC accelerator and paid transactions accelerators. ViaBTC is free, but has the limit of 100 transactions per hour, so you have to set your clock. Other paid accelerators charge you a fee for rebroadcasting the transaction, few are moderate, rest are insane.
Can u make a recommendations on ->>> paid transactions accelerators

there is also this one if viabtc is saturated
https://www.antpool.com/user/prioritiseTransaction.htm?m=savePrioritiseTx, but if you are not a bitmain supporter or hate their decision about mining, then don't use it
anyway i've noticed that miners will confirm very high fee transaction regardless if these transaction meet the average or minimum fee needed, i've done some test with my transaction, and they always get confirmed
for example a 900 bytes TX that now would require 320k satoshi to be confirmed, will be confirmed with 200k easily
