Auto Stamp
Read full descriptionHide full description
AutoStamp, your digital record of validated work on your vehicle. Includes Proof of Work with images taken while work is carried out. Typically vehicles have that thin paper booklet for routine service stamps to note.... if you remember... oh and if you still have the booklet at all that is. A record of the history in this way has been the accepted way for many years, though at the end of the day it's just a smudgy mark in a book. Was the service done? Was it done well? Where do I record that repair on my car? What about modifications? This app not only gives you a way to record ALL work done on your car, it actually validates the work and requires Proof of Work with it. You can insert work that has already been done on the car too... but you'd be wise to have the proof at hand, like receipts or photos. If you're like me, who loves to work on my own machine, taking copious amounts of photos was always part of my routine... if nothing else so I could look back and see how that part should be positioned when putting it back on. Download it... play around with it, you should quickly see the value and what you didn't even realise you've been missing all these years. This is the initial version, the one to kick off the trend, though in the background we're working on many additional features that will appear in future updates. Selling your car on? - Just think, if a full service history adds value when selling your car, think how much more value can be achieved with ALL history, in one digital fully transferrable package! Enjoy!
