Chronicle Bill Organizer app overview

[MegaAVINASH]

Is there any alternative to this?
I am using from past 2/3 years but this is paid amd that to subscription based. I am looking for one which has one time pay.

Main purpose is
1. To have widgets that remind me and
2. add bill amount(optional). Other apps have these features. But none of the apps have one feature which is leaving the amount part empty during the reminder. I have credit card bill which is not same every month
