Friends of Friendz vs Delphi: An Honest Comparison

If you've searched for a flatmate-matching app, you may have come across Friends of Friendz - a platform built around connecting you with compatible people through an algorithm rather than a fully open listings board. Here's an honest comparison with Delphi.

What Is Friends of Friendz?

Friends of Friendz has a genuinely interesting origin story. It started as an Instagram account, where its founder shared spare-room posts and tagged the original poster so people could message them directly - growing to over 40,000 followers before becoming a full app, now available on iOS and Android. It's since expanded beyond London to New York, Paris, Berlin, and Amsterdam.

Key features include a compatibility-matching algorithm (matching based on lifestyle and personality rather than just listing browsing), in-app scheduling for viewings, and a "buddy up" tool for pairing with others also searching for a place. It's not gender-specific - open to all genders, matching on compatibility rather than a structural filter.

Friends of Friendz vs. Delphi, at a Glance

	Friends of Friendz	Delphi
Format	Dedicated app	Dedicated platform
Audience	Mixed - open to all genders	Women-only

Geographic reach	London + 4 other international cities	London-focused
Origin	Grassroots Instagram account, grew into a funded app	Built specifically as a women-only platform from the outset

Where Friends of Friendz Does Well

Genuine grassroots trust. Growing from real Instagram community engagement to 40,000+ followers before becoming an app suggests organic trust was built early, not manufactured from day one.
Compatibility-first matching is a genuinely useful mechanic if lifestyle fit matters more to you than browsing raw listings.
International reach - useful if you're comparing options across cities, not just London.

Where It Falls Short If You Specifically Want a Women-Only Community

Not gender-specific. The compatibility algorithm matches on lifestyle and personality, not on the same shared baseline priority a women-only community offers structurally.
Matching individuals isn't the same as community-wide alignment. Being matched to a compatible person is different from every single person on the platform already sharing your one non-negotiable priority.

Why Delphi Is a Different Kind of Answer to the Same Underlying Need

Friends of Friendz exists because people want more than a fully anonymous listings board - that instinct is right. Delphi answers a related but different need: instead of an algorithm finding you a compatible individual, every member is already part of one shared, women-only community from the start. The filter is structural, not just algorithmic.

That said, using Friends of Friendz alongside Delphi isn't a bad strategy if you're also open to comparing options more broadly - they're not mutually exclusive.

Frequently Asked Questions

Is Friends of Friendz free to use?

Check the app directly for current pricing - this can change and isn't something we track independently.

Is Friends of Friendz available outside London?

Yes - it's expanded to New York, Paris, Berlin, and Amsterdam alongside its original London base.

Is Friends of Friendz women-only?

No - it's open to all genders. If a women-only community specifically is what you're looking for, that's where Delphi differs.

Should I use Friends of Friendz instead of Delphi, or alongside it?

Alongside it, for most people - they solve a related but different problem (compatibility-matching versus a dedicated women-only community), and using more than one search channel is generally a good strategy.
