I built a Tinder-like iOS app to clean 3,000 contacts - looking for honest feedback

Hi Indie Hackers 👋

I want to share a small personal project and get some honest feedback from people who’ve been through this before.

A while ago my wife showed me her iPhone contacts and said:

“I have more than 3,000 contacts here. Cleaning this manually is impossible.”

She was right.

iOS doesn’t really offer a convenient way to review and delete contacts one by one — especially when you’ve accumulated years of old numbers, duplicates, and people you don’t even remember anymore.

So I built a small iOS app just for her.

The core idea is very simple:

• one contact at a time

• swipe right → keep

• swipe left → delete

• basically Tinder, but for contacts

Surprisingly, this turned a boring chore into something fast and even a bit enjoyable.

That made me think this might be a common problem, so I cleaned up the app and published it on the App Store.

Reality check 😅

After a month, the app had only a couple of downloads.

Now I’m trying to understand:

1. Is this actually a real problem for more people, or just for us?

2. Is the value proposition clear enough?

3. How would you explain this app to a potential user in one sentence?

Pricing transparency:

The app uses a subscription model with a 3-day free trial, which can be canceled anytime during the trial without being charged.

I’m not here to hard-sell — I genuinely want feedback:

• would you personally use something like this?

• what feels unnecessary or confusing?

• what would make it a “no-brainer” for you?

If you’re curious, here’s the app:

Thanks for reading, and I’d really appreciate any thoughts 🙏
