Even if someone uses your product a lot, they'll start to take it for granted. They'll forget what life was like without it.

Reminding them of that value helps make them value you.

Instacart, the grocery delivery app, does this for time and money.

They continuously remind you of the amount you’re saving due to being a premium user (free delivery and reduction in fees), as well as the time you’ve saved so far.

And to celebrate submitting an order, they show you how many hours you’ve saved and how many orders you’ve completed since you’ve started using Instacart:

This is clever because it makes me:

1. Feel like my $100 per year Premium subscription is justified
2. Appreciate how useful Instacart has been
3. Realize just how many times I’ve used it. They use your past behavior as proof.

A few more rapid-fire examples

Opal tells you how much you’ve reduced screen time

Imperfect Foods tells you the impact you’re making

“Groceries that help you fight food waste.”

So it makes sense to highlight the impact:

Toothpaste and mouthwash famously does this

Does mint make your mouth cleaner? No.

Does mint make your mouth feel cleaner? It sure does.

Just like manufacturers add palm oil to shampoo to make it foamier. Because foam is a cue that shampoo and soap is working, even if it doesn’t do anything.

Lastly, Wealthsimple reminds you how much interest you’re earning on your money:

Some quick tips

• Remind people of your value as they use it and asynchronously with emails, push notifications, and texts. Keep doing it for as long as they're a customer.
• Only focus on what they likely care about most:
  • Time
  • Money
  • Impact
  • Efficacy
• Remind people of the:
  • Immediate value: what you’re getting now
  • Historical value: what you’ve gotten so far
  • Future value: what you’ll get if you keep doing it for life
• Make the impact seem larger by increasing the time scale.
  • You’ve saved 300 hours since downloading the app.
  • You’ll look at your phone 11 years less in your lifetime.
• If your product does things in the background (like Wealthfront’s tax loss harvesting), send push notifications indicating it’s working hard for them.
• Look for ways to make your product feel like it’s working. That could be both from clever psychological tricks (mint in toothpaste) or by leveraging the labor illusion (showing the effort you’re putting in).

Remind them how you’re helping them, and your customers will value you more and for longer.
