12 Apps, 120,000 Installs, $252 a Year

Account Manager
Offline, password-protected daily income and expense tracking with backup and restore.
About Account Manager
Account Manager is a straightforward daily accounting app for people who want their money records on their own phone rather than in the cloud. It stores debit and credit transactions across multiple named accounts and works entirely offline.
The app has passed 10,000 downloads and is built around three things its users asked for repeatedly: speed of entry, password protection, and a backup you actually control.
