Android/iPhone/Web: Keeping track of all the various details about your cars, whether it's service records, receipts or whatever else, can be a bit tough. But if you're sick of just stuffing all of that into the glove box, AUTOsist is an app that manages it all for you. With AUTOsist, you simply set up a profile for your cars, then you can add service records and receipts as you get them with a built-in scanner. You can then set up reminders for services so you're always up to date. Beyond that, you can also store specific info, like insurance documents or your registration, so it's easy to pull up info when you need it. Better yet, if you decide to sell the car, you can easily transfer all that info to the buyer, so they will instantly have a full service record.
The basic account is free and allows you to manage one vehicle. If you need more, you can upgrade for a one-time fee of $US5-$10 ($7-$13) depending on your needs.
