Consider possibility of a mobile Money companion app

One of the most annoying things about using a home financial app is having to update it from paper receipts (assuming that you even get one these days) it would be great to have a companion app that simply allowed the capture of transaction data on a phone. Does not need to be complicated...just select account, enter payee, date (but default in today), reason & amount...then update, with option to review & amend transactions entered. Upload to a cloud repository. Then synchronise with main app when it is next opened on one's PC. Cover cost through a simple subscription service for the companion app. Think this may well be a real plus point. Regards, Solly
