Please allow the early adopters to restore their purchases, as I’m not willing to pay for the app I purchased again. In particular since no new features were introduced in years and the app just had a facelift. ### 4/5 — Good *2025-01-11* But need to understand. There can be a little more guidance how to use the app. I am looking for some tool which allows us to draw any shape like square, triangle, rectangle etc on the ground with measurement. ### 5/5 — It’s simple / Works *2024-04-11* Its been on my phone for a bit and I haven’t deleted it. App's not all fancy like some and - I use it at work for a couple things and haven’t had a problem - It works. ### 1/5 — Wasted my time and money *2024-01-30* I purchased the pro version but it never was pro still had adds in it.fsiled to go to pro no matter what I did. Reinstalled it over and over again. I liked the app it was nice. ### 4/5 — Helpful app *2023-09-03* I like your app and find it useful. Since you’ve disabled the feedback via you webpage, I would like to ask for a few changes if possible. 1. I’m using a ruler almost exclusively. It would be nice for the app to go back to a previously opened tool or designate a default tool in settings to open when one opens the app. 2. Ruler automatically opens in metric measurements and I use inches/imperial ones most of the time. It would be great to allow users to make their default choices. 3. While I understand that all of the app features are in landscape position, it would be good for the screen that selects the tools to rotate to whichever position the phone is rotated. Thanks! ### 2/5 — Dezibelmessung grafische Umsetzung unklar *2023-07-13* Ich verstehe die grafische Umsetzung der Audiopegelmessung nicht. Wiese sinkt der angezeigte Dezibel Wert bei lauter werdendem Audiosignal? Ein paar erklärende begleitsätze zu der App fehlen mir. ### 1/5 — Necesita mejoras *2023-03-10* Ahora no funciona en iphone 13 pro ### 3/5 — G8TKeaper *2020-04-07* First and foremost, this is an outstanding tool, containing all the approate tools I need in one App; however having said that one might question why I have given Only 3 Stars . . . well I liked this app so much that I Purchased the Premium Version . . . which was supposed to REMOVE the ADVERTISEMENTs . . . IT DID NOT REMOVE THE ADVERTISEMENTs! I sent a note to the products authors . . . to NO AVAIL. I still have ADs in my version! Does the App work? Yes the App works very well, BUT it still has the Advertisements in it, which IS ANNOYING, AT A MINIUM! Please REMOVE THE ADs in The PREMIUM EDITION ! ! ! Thank You ### 4/5 — Very good product. *2020-03-31* I especially like the audiometer. I would love to be able to use this to confirm that what I am hearing from my speakers is true to form. By comparing a flat audio playback through a digital source, then use the audiometer like a mixing board / equalizer to bring in what the studio wanted me to hear. Thanks so much. ### 3/5 — Finger weg *2020-01-13* 3,15€ sinnlos vergeudet, ungenau außer vielleicht Lineal, Audiometer stürzt nur ab. **Developer response:** Hallo, schade, dass Ihnen die App nicht gefällt. Um die Genauigkeit der Winkeltools zu erhöhen, sollten Sie die Kalibrierung durchführen. Die finden Sie in beiden Tools unter Einstellungen. Danach sollten beide Tools auf 0.1 Grad genau messen. Wegen des Audiometers werden wir prüfen, ob wir einen Fehler finden können. Falls Sie uns unter contact@jrsoftworx.com beschreiben könnten, wann der Fehler auftritt, würde das sehr helfen. ## Frequently asked questions about Measure Angles & Bubble Level ### What is Measure Angles & Bubble Level?
