This makes the app especially helpful for people who want automation that adapts to their lifestyle rather than rigid rules.

8. 8. Dobot Helps You Save Through Visual Goals and Automatic Round-Ups

Dobot lets you create visual savings goals, like trips, holidays, or emergency funds, and then saves for them automatically using round-ups and small scheduled transfers that add up without pressure.
