Settle Up for Android will let you share expenses with roommates, colleagues and others. There's an iPhone app as well, which makes it easy to share expenses with non-Android users. There's also a very basic web app that requires a Google login.
Settle Up works well on Android tablets and phones. It will split bills evenly or in differing amounts by person and allow you to attach receipt images. The app lets you pay those you owe via PayPal. If you have a lot of expenses in a group and you need to do an analysis or graph using a spreadsheet program like Excel, then you can export data or import it to your SD card or email using the CSV format.
Settle Up supports multiple currencies and has been translated into 20 languages. You'll see some ads unless you remove them with an in-app purchase. Other in-app purchases include adding the ability to filter payments and convert debts to a single currency.
Cost: Free, with optional in-app purchases of $0.99–$19.99 per item

The app offers views of all of your balances between individuals and groups, as well as your total balances across all of your groups and friends. You can make payments directly from your phone and choose to be notified when expenses are added or paid. If you choose to receive them, the app will also send automatic reminders to pay what you owe.

Receipt Ninja splits bills and expenses, and tracks who still owes money and how much. The app offers different ways to share the splitting details with group members, including via SMS text, email, Google Drive or Dropbox. You can sync data with other users as payments and splits are made if they use the app, and you can snap photos of your receipts (unfortunately, you can't share those photos through the app, but you can share them via Dropbox or Google Drive).
If you need to analyze data for a large group, Receipt Ninja exports data to CSV files for use with spreadsheets like Excel, and also backs up data to an SD card, Google Drive, or Dropbox.
Receipt categories are customizable, and it's easy to add group members with names, email addresses and mobile numbers. The app offers support for multiple currencies, as well. The reports are easy to read with monetary value and percentages.
There's a free version of Receipt Ninja, but you'll need to endure some ads in the app, and event syncing is limited. The paid version eliminates ads and offers unlimited syncing.
