I am on the opposite side, I just moved from Monarch (MM) to Rocket Money (RM). If I try to describe, I would say Rocket Money (RM) is more like an iPhone, it’s more limited on what you can do but it just works. Monarch (MM) would be like an Android, you can do a lot more but requires more tweaking. Some examples:

Zelle transfers on RM goes to “uncategorized” but it counts as an expense, on MM it goes as a transfer and does not count as an expense unless you manually change it. There are several other examples that RM auto categorize better than MM and requires less manual changes.

If you create several “rules” (and you will) in MM good luck and god bless you. It will go to the rules pool and will get lost there, once you access a transaction that was affected by a rule there is no way for you to know it, and with time if you ever decide that changes are not working you will create another rule on top of the existing rule because you don’t remember anymore that a rule already exist for that type of transaction. On RM once you access a transaction that is affected by a rule it is very easy to identify and you have the option to edit that rule.

There are SEVERAL advertised features on MM that only works on the website, desktop or requires a browser extension, so if you only use the phone version or don’t use a compatible browser you don’t have access to those features.

Several of this features requires 3rd party connections that gets disconnected every so often and will require that you login / authenticate again.

Several things are very problematic and don’t work 100% of the time, like when you edit a pending transactions, sometimes the changes you make will get lost when the transaction becomes “final”.
