Atom bank review
A mobile-first option for UK savers who want savings accounts and mortgage tracking in one app.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Atom bank is a UK app-based bank for people who want to open and manage savings accounts on a phone, with mortgage information available in the same app for Atom mortgage customers. Its iOS and Android app offers instant-access savings, fixed-term accounts, an easy-access Cash ISA and an Instant Saver Reward account. The product is a fit for mobile savers who also need to keep track of an Atom mortgage, rather than people seeking a broad everyday banking account.
Savings choice is the main strength. Instant-access savings allow unlimited withdrawals, while fixed-term accounts have terms from six months to five years. The Instant Saver Reward account has reward and withdrawal interest rates; the listed Instant Saver rate is 2.50% AER variable. Rates can vary by product and term. Atom bank's pricing model is free, and the product is described as having no listed account fee. Buyers comparing returns should consider the relevant product and term rather than treating the variable rate as fixed.
The app also supports mortgage tracking and device security, biometrics or a passcode for login. Customer support is available through in-app chat, phone and email. The trade-off is a narrower banking scope: Atom bank's product offering centers on savings and mortgages, rather than a general current account, and it has no branches or customer-facing web banking login. Choose it if mobile savings and mortgage tracking match your needs; consider another bank if branch access, web banking or a current account is essential.
