How Do They Actually Perform?

Cleo – Encouraging and Informal

After testing Cleo for two weeks, it managed to save £22 using its Smart Save feature. The app sends daily messages about your spending habits, some blunt and some humorous, and provides small nudges to help you improve. If you enjoy a more casual, fun experience while managing money, Cleo delivers.

Plum – Quietly Effective

Plum was able to save £74 in just under a month through its automatic savings system. Once connected, it worked in the background without the need for constant interaction. It also offers investment options and the ability to divide savings into “Pockets” for different goals like rent, travel, or an emergency fund.

Real-Life Use Case: Freelancers with Irregular Income

Let’s take the example of a part-time freelancer based in the UK. He connects Cleo for everyday spending accountability and Plum for long-term savings.

After 6–8 weeks:

  • Cleo helped track and reduce overspending.
  • Plum automatically saved over £100 without any manual transfers.
  • The combined use resulted in better money awareness and the start of an emergency savings buffer.

This setup works well for anyone whose income fluctuates — creatives, gig workers, side hustlers — because it removes the pressure to manually budget each week.


Potential Drawbacks

AppLimitation
CleoBest suited for younger or tech-comfortable users. May feel too casual for some.
PlumInvesting features may feel complex at first. Some tools only unlock with a paid plan.

So, Which One Should You Choose?

  • If you want motivation and a bit of personality in your money app: Cleo is a great place to start.
  • If you prefer a quiet, more traditional approach that just works in the background: Plum is a solid choice.
  • Using both together is a smart strategy. Cleo helps you reflect on your day-to-day spending, while Plum builds long-term savings and even investment potential.
