This app is very well-done! Thank you Dr. Ullman!The tablet edition has been updated to include single lines of letters as large as 20/200 calibrated for a 10 foot viewing distance, which seems to be about the limit of what the tablet screen size will display. This distance chart is a huge plus for the tablet edition, and a major reason to justify a separate purchase from the phone edition since the larger screen is really needed to display distance size letters.The distance chart is very useful if you have a presbyopic emmetrope who doesn’t carry reading glasses and so you have no reading glasses available to check acuity. Obviously in a clinic these supplies would be available, but for things like hospital consults or on-the-fly needs, where you may be more likely to utilize a phone or tablet for an acuity check, and may not have every supply, this comes in very handy.It’s very full-featured and works great! There is a feature that attempts to use whatever front-facing camera is available to check the distance from the screen to the tablet for near acuity checks. This works really well if you have Face ID on the tablet/phone. Otherwise it kinda works (it’s really just a bonus feature anyway, and it’s not the app’s fault that the hardware is limited in its capabilities).
