High Yield
Our review
Alto offers a simple place for savings, with a deliberately limited set of ways to reach the money.
Alto is easier to understand if you give it one assignment: hold savings that can move through a linked bank account. It is an online savings service under BMO Bank, rather than a replacement for every part of your daily banking. The absence of an opening minimum and monthly maintenance fee makes it approachable, but the access arrangement deserves as much attention as the yield.
One external link and a deliberately limited service
The application may be online, but Alto's limited access options make the first withdrawal especially important. Reddit discussions from its 2023 launch include reports of joint-account setup problems, missing transfer status and repeated calls to recover outgoing funds. One poster later said an escalated complaint resolved the transfer. Those older anecdotes are a reason to test the current process, not proof that today's customers will have the same experience.
The external account is effectively Alto's front door and exit. That arrangement can be perfectly workable for a reserve that is replenished from the same checking account and spent only occasionally. It becomes less comfortable if you regularly change primary banks, expect to pay someone directly, or need several ways to reach cash. The absence of wires matters particularly for a large, dated expense. Paying a wire fee elsewhere can sometimes solve a timing problem; here, there is no wire feature to buy. A higher savings yield should therefore be compared with the amount of money you would still keep outside Alto for those situations.
Bankrate describes Alto as a basic online account with limited access features. Its review calls out the lack of ATM access, a mobile app and mobile check deposit. That is an important distinction for someone who assumes a familiar bank name means all of that bank's services are included. A simple website can be enough for savings; it needs to match how you will fund and withdraw the money.
A browser-only account is not necessarily hard to maintain. For someone who checks savings on a computer and rarely touches it otherwise, a separate app might add no value. But the lack of mobile check deposit, a card and branch service makes this a deliberately narrow product. BMO's broader banking capabilities should not be mentally added to Alto's feature list. That is also why general reviews of BMO checking are a poor guide to this account. The savings experience turns on Alto's own linked-account process and remote support, even though the legal bank behind the deposit is a familiar institution.
The terms and the experience when help is needed
The account information reviewed lists no required opening or ongoing balance. New accounts must be funded within 90 days. There are no branch services, debit cards, checks or wires for this product. Alto is a BMO Bank trade name, so deposits you already hold at BMO can affect your total insurance coverage. A second brand does not automatically provide a second insurance allowance.
Alto's lack of branch and ATM access makes remote support especially important when a transfer needs investigation. A useful resolution would distinguish a request still pending at Alto from money already sent to the receiving bank; simply being able to reach a representative does not establish either outcome. Alto is a BMO Bank trade name, so deposit coverage must be assessed with the relevant BMO balances. That bank relationship establishes where the money is held, rather than providing evidence about how promptly this particular service resolves an exception.
The public discussion is more balanced than a collection of launch complaints alone would suggest. In a 2024 savings thread, one customer described satisfactory use and a transfer that took one business day for that person. Older 2023 conversations describe the opposite experience: uncertainty about whether withdrawals had been accepted and difficulty obtaining a useful status update. Neither is a current processing promise. The contrast identifies a specific service issue worth caring about: whether the interface and support can tell you where a transfer stands. That information matters much more than whether the website looks modern or has an extensive list of features.
Where I would use Alto
Alto's simplicity comes with a real tradeoff: there is no outgoing wire, card or branch route to fall back on. That makes the linked external account part of the savings arrangement, not just an opening formality. I would use Alto for money whose spending date can move, rather than a closing balance that must arrive on a particular morning. Someone already holding deposits at BMO also needs to consider the combined insurance exposure before treating Alto as another place to spread a large reserve.

I would want a meaningful ongoing advantage before adding Alto alongside another competent online savings account. A small introductory-looking gap in a comparison table can disappear while the work of maintaining another relationship remains. For money being accumulated over several years toward a flexible goal, the limited features may be an acceptable exchange for return. For a home purchase whose closing date is approaching, the same design creates a constraint that extra interest cannot remove. Someone who already holds substantial BMO deposits should also recognize that changing the logo on the login does not necessarily spread the deposit risk across another bank.
