Literally **Developer response:** We sincerely apologize for the experience you had. You’re right, 5 seconds is far too often for anyone to get work done. We’ve taken your feedback seriously and have just released a new update (Version 3.1.6+) that drastically reduces the frequency of ads. Our goal is to make measuring effortless, and we hope you’ll give the new, cleaner version a try. ### 5/5 — My review *2025-12-09* I love this app it’s cool, I want no adds button **Developer response:** Thank you for your kind words and for loving the app. We truly appreciate your support. If you are looking for an ad-free experience, please note that there is a subscription and lifetime unlock option available in app settings. ### 5/5 — Very useful app! *2025-02-20* Reset Scale to Original is not working in either Horizontal or Vertical ruler. When I pinch to size an image small and then back to 100%, the app automatically resizes my image to 109%. It will not let me size it to 100%. Or the app thinks it at 100% but falsely states it as 109% Please update this for the latest version of iOS & iPadOS and correct the minor issues I pointed out. Then you should charge a small price for this app to cover your time to keep it updated. **Developer response:** Thank you for taking the time to share this detailed feedback. We’re sorry for the inconvenience with the scale reset, and we’re already looking into improving this in an upcoming update. Your notes about iOS/iPadOS compatibility are truly appreciated. Thanks again for helping us make the app better! ### 5/5 — Very useful for telescope collimation *2022-02-09, version 3.1.0* Aligning mirrors on a Newtonian telescope can be tricky. Aligning the secondary mirror with the focuser is even harder without using an expensive concentric circle eyepiece, which I do not own. Using a collimation cap, I took a photo using my phone and used this app to check using the protractor tool - it’s easy to centre the overlay so the edge meets the focuser tube, then zoom in to check if the secondary is a) centred and b) circular. Easy! ### 5/5 — Measures pixels between two points in an image *2021-05-18* This exactly what I needed to measure the distance between two isobars on a weather map. Having the angle between the two points is neat. One possible improvement would be to have a measure tool that returns distance (and angle) instead of reading off a ruler. **Developer response:** Thank you for the great review! We're glad the app helped with your weather map measurements and that the angle feature was useful. We appreciate your suggestion about a dedicated distance tool, it’s a great idea, and we’ll keep it in mind for future updates. Thanks for sharing your feedback! ### 2/5 — ???? *2020-09-08* I have no idea what the units of measurement are. Pixels? Mm? Certainly not cm or inches, which is what I was looking for. I wouldn’t have even thought to rate this if it hadn’t left me with such confusion. Any sort of labels would’ve changed this to no review, or even a four star. But I’m just confused. Which is disappointing. At least you can upload images of your actually screen, which is more than I can say for the last app I tried. That’s keeping this from a one star. **Developer response:** Thank you for sharing this thoughtful review. We’re sorry for the confusion around the measurement units and truly appreciate you pointing it out. Clear labels are already on our improvement list, and feedback like yours helps us make the app better. Thanks again for taking the time to let us know. ### 5/5 — Guide line for beading pattern etc *2019-11-13, version 3.1.0* Just what I’ve been looking for. I screenshot beading patterns to follow and tried using the one in Edit on the iPad but the ruler kept disappearing from the options so looked for an app. After trying several ruler apps that didn’t do what I needed, I finally came across this one which works perfectly for what I need. I can use it on the screenshot, moving it up gradually each row. It’s also very handy as it is translucent when moving so i can see clearly where to put it, but solid colour (you can choose the colour) when placed so much easier to follow line of beads etc above it. Could be used for any kind of pattern ie knitting, tapestry, weaving etc or as a ‘reading line’ as I used to have in my real books ( it’s a dyslexia thing), to help read a screenshot. Obviously it can also be used as a ruler but I have loads of rulers. This app has saved me loads of time transposing patterns onto paper so I could use a real ruler to keep my place. Im a very happy customer, thanks. ### 5/5 — Love it! *2019-10-24, version 3.1.0* I use it to keep my place on crochet patterns. Only downside to it, when you load it up, it uses the last photo you took, if you could select a new photo if you wanted one, and by default it stayed the same, that would be better. Edit: I can pick the photo I want to use the app with, but it doesn’t remember this photo and ruler placement the next time I use the app. ### 2/5 — Not ready for Primetime *2017-07-26* First time you open this app, it remains on. No off switch. I'm not sure if the measurement is in pixels or whatever. I can't use this. **Developer response:** Thank you for the feedback. We’re sorry for the confusion, measurement changes will be available soon in the next version, and you can easily close the app from the home indicator or app switcher. We’re working to make this clearer in future updates. If you have any other issues, we’re here to help! ## Frequently asked questions about Screenshot Pixel Measure Tool ### What is Screenshot Pixel Measure Tool?
