## What is Cost Split?

Cost Split helps you share costs within a group of people where each person can add expenses from their own devices thanks to the cloud sync.

5.0 average rating in US, UK and Sweden

Top 10 in the Finance category in Sweden, India, Denmark, Poland, Slovenia, Finland, Norway, Turkey, Chile, Argentina, Czech Republic, Philippines, Luxembourg, Lithuania, Venezuela, Iceland, Latvia and Norway.

It is perfect on vacations, road trips, a night on the town or in a household where you share the costs. Just define a group of people, add expenses as you go and when you are ready to settle the debts, you can e-mail a report with a list of all expenses and who should pay what to whom.

You can choose to store the data online, so all your friends can view and add costs themselves. Thanks to the currency and offline support, it works perfect when you are on a trip abroad with limited internet access.

### 4/5 — Fehler bei Aufnahmen

*2026-03-15*

Grundsätzlich eine sehr gute App. Leider stürzt seit einiger Zeit die App ab, wenn man versucht eine Rechnung direkt aus der App zu fotografieren. Es ist nur noch möglich vorher die Fotos aufzunehmen und dann hochzuladen. Das ist extrem nervig und wird hoffentlich bald behoben.

### 2/5 — Can’t download currency rates

*2026-02-16, version 3.4.1*

Despite the option of being able to post transactions in different currencies you are unable to download the exchange rate so the tallied amounts end up being completely wrong. No way of contacting anyone despite the developer happily taking dollars for “premium” version

### 5/5 — Improvement

*2025-11-28, version 3.4.1*

Been using this app for over 5 years now. Its great, I just wanted to make a recommendation to add a search option so that people can search for a specific expense/transfer made a while back

### 4/5 — Kategorien fehlen

*2025-10-21*

Grundsätzlich alles super übersichtlich, allerdings fehlt mir die Funktion Ausgaben in Kategorien einzuteilen.

### 5/5 — Will die on this hill; this is by far the best cost splitting app

*2025-10-10, version 3.4.1*

What the title says

### 5/5 — Excellent app

*2025-09-21, version 3.4.1*

I use this app every time I travel with friends. It make so much easier and also it’s a log of my expenses on my travels, I can always go back and retrieve what I spent and even where I ate if I input the name of the restaurant.. great resource

### 4/5 — Only needs one more thing to be 5 star

*2025-08-17, version 3.4.1*

Very much like this app. The only thing holding me back from a five star rating is its usage of the Apple mail app. There doesn’t seem to be any way to override to either the Outlookmor Gmail apps

### 5/5 — Great app, need text option

*2025-08-11, version 3.4.1*

The app is simple, clean, and effective.  I highly recommend it.  The only challenge I have is that I use the Microsoft mail app and it won’t let me generate the summary reports (I assume it uses the iPhone mail app as the default).  Including the Microsoft mail app it allowing a MMS report generation/ send option would help with that.

### 5/5 — So far, very useful

*2025-08-07, version 3.4.1*

I tried a few cost shearing apps and only this one, as far as I can tell, does it with option other apps do not offer. Recommended

### 5/5 — Excellent App

*2025-05-07, version 3.4.1*

I love the app. It’s so easy to share expenses for a trip or project. I have a suggestion,  once everyone in the group has paid and they show zero there should be an option to change the group color, so I know that event is complete.
