Can you share how you track your credit card expenses and miles rewarded (e.g. on Excel)?

As a fellow DBS CC user I feel your pain.

What I'm currently doing is manually entering into the seedly app as I find it the most convenient (no need to remember and key in at home, can track immediately).

I have reduced the SMS alert for my card to anything over a $1 transaction. This way I have a record of most of my CC spend on my SMS to double check.

Lastly, I check the ibanking record every week as there are certain transactions that are not SMS to me (like recurring transaction for phone bills)
