I've tried several receipt tracking apps, and they all failed to overcome the OCR challenges. If there is even a 20% chance the app cannot recognize the total amount (ignoring taxes and tips), then suddenly I am manually reconciling unrecognizable receipts. So, if I'm always manually reconciling expense reports, then why bother with an app... I'll just continue taking pictures and forwarding them to my email for manual expense reporting. 100% of the task can be done in one sitting. That being said, I SINCERELY HOPE somebody WILL develop the machine learning algorithms necessary to get 99% OCR accuracy in this space.
