Gas Mileage Logger

Back in the olden days, I used to keep track of the gas mileage of my 1996 Buick Regal by jotting down the odometer reading on the receipt from the gas pump and entering the values into a spreadsheet. It was useful to see the seasonal variation in gas prices, gas mileage, and my driving habits.

The Gas Mileage Logger app lets you do that all automatically on your phone. Enter your odometer reading and fill-up amount each time you get gas and see the true tank-by-tank gas mileage of your vehicle, not the over-averaged value your car shows on the dashboard.

This app also lets you import the EPA fuel economy ratings for your vehicle to compare your actual mileage against.

Features

• Track unlimited vehicles
• Import and export data to CSV files to Google Drive, Dropbox, or any other location on your phone or tablet
• Links to EPA ratings for vehicles from 1984 onward to let you compare your actual mileage with your vehicle's rating
• Compatible with US and international units (US Gallons, UK Gallons, Liters, Miles, km)

Rent or Buy?

If you are trying to decide whether to buy a home, you want a complete picture. Most online calculators focus on monthly payments and miss the bigger picture. The Rent or Buy calculator app takes that to the next level by including investments and opportunity costs on an equal basis between a renter and homeowner. Don't neglect the opportunity cost of that hefty down payment, or the cost of home maintenance!

How does it work? Consider home-owner Jane and renter Joe. On day 1, Jane pays $40,000 for her down payment and $3,000 in closing costs for her new $200,000 home. Joe pays a $1,000 deposit to rent an equivalently sized house and invests the difference of $42,000 in diversified index funds.

Joe's rent is $1,000 per month for the first year, and Jane's mortgage payment is fixed at $752. However, her total cost the first month is $970, including tax savings, insurance, property tax, and maintenance. Her costs are $30 less than Joe's, so she invests the difference each month to keep the comparison fair. Inflation increases Jane's taxes, insurance, and maintenance costs, and causes Joe's rent goes up every year. Jane's house also increases in value. In this scenario Jane pays less than Joe every month, so she is investing the difference each month while Joe's initial investment continues to grow.

After 30 years, who has a higher net worth; Joe or Jane? In this case, they both have about $620,000, but Jane has a lot of her net worth in her house.

Put in your numbers and see how your comparison comes out in your housing market!

New Child Growth Tracker App

Child Growth Tracker has moved to its own page, here!

My new growth tracker app is in the Google Play store! After needing to track percentiles for both my kids and not finding many good options for doing so that included gestational age curves, I decided to make my own.

Record multiple children's weight, height, and head circumference measurements and use them to generate growth charts and percentiles from birth to up to 20 years of age. 

Both the CDC and WHO charts are included, as well as the Fenton gestational age charts for pre-term babies or ultrasound measurements. All percentiles are calculated using the same high accuracy LMS method doctor's offices often use.

You can save images of your child's charts or percentile tables to share, put in a baby book, or take along to discuss with your child's doctor.
