Hopefully the acronym-laced title didn't scare anyone off. Well, now that you're here - please let me know what Applications you find to be of a Mustachian bent. I see alot of posts around these forums that could seriously benefit from user friendly apps (both gross and granular). Perhaps they exist already, perhaps not. Naturally free is best, but a few dollars for a spectacular app could be gold.
In general, for the Mustachian community - and the population at large, a large problem when comparing to others is that we're often showing each other slightly different numbers that are in different formats with different references etc. Having a standard app (and being able to specify a particular standard output) would go along way to analyzing and comparing usage/spending of whatever area you want.
Another feature of interest would be apps that send data to a open or closed group within a cloud environment with the purpose of populating a 'challenge'.
A couple areas that I see opportunities (if a product doesn't already exist); based on interest in the forums to kick it off:
1) Tracking spending of groceries - this would require a fast and dirty OCR app to scan your receipt and quickly be able to send items to categories, keep running totals of spending, be able to upload a snapshot of a specific time period etc.
2) Electricity - a simple app with fields that you input certain key numbers that allows different calculations to be made.
3) Bike/Run etc challenges - We have a pretty clumsy sheet in the gauntlet area that takes alot of upkeep etc. An app where you input your distances etc for the day and the data populates a closed group cloud environment.
4) Savings rates, spending rates, net worth, etc - again, could be as 3) above.
Since I've no coding/app development experience at all - I'll let those that do chime in. I have no idea what it would cost/time required for someone/s to (using one of the above as an example) develop...but I would think there would a good side gig in it...
Of course, if anyone has suggestions for any kind of Mustachian-app, I can populate in the message below this one a list of useful applications.
