Auto Stamp vs PD Meter

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!

Ordering glasses online and need your PD? PD Meter helps you measure your pupillary distance (PD) in millimeters using a front-camera selfie and any standard-size card, like a credit card, for scale — no ruler, no second person, no trip to the optician. Your pupillary distance is the gap between the centers of your pupils. Online eyewear stores ask for it so your lenses are centered correctly in the frame. PD Meter gives you a quick, repeatable estimate from the comfort of your home. HOW IT WORKS • Hold a standard card (a credit card, ID or any ISO-size card) under your eyes — its known width gives the app a real-world scale. • Take a front-camera selfie, looking straight at the lens. • Mark the center of each pupil and the edges of the card. • PD Meter converts pixels to millimeters and shows your PD instantly. WHAT YOU GET • PD in millimeters, ready to enter at checkout. • Single (binocular) PD, the value most retailers request. • A clear, guided flow with on-screen tips for good lighting and head position. • Re-measure as many times as you like and average your results for confidence. WHO IT'S FOR Anyone buying prescription or blue-light glasses online, parents checking a child's fit, or anyone who simply wants their PD on hand without booking an appointment. A NOTE ON ACCURACY PD Meter provides an estimate based on your photo and the card scale. Results depend on lighting, camera angle and how precisely you place the markers. For high prescriptions or progressive lenses, confirm your PD with an optician. This app is not a medical device.
