Been using for years. Today had trouble when using along with a spirit level. Checked app against my old 2 ft spirit and my 4 ft stabila level. The spirit levels matched, but the app was off. App approximate, but not precise. ### 1/5 — Worthless *2023-03-24, version 2.8.1* Paid 3.99$ for nothing. Does not calibrate. ### 3/5 — Deceptive *2023-02-02, version 2.8.1* Does not show in-app purchase or price, so assumed it was free. It’s not. You get limited access until you either pay to upgrade to “Pro” or you can get a one-day pass to Pro by wasting time watching some stupid, irrelevant ad. I get trying to make money, but this approach is highly misleading and deceptive. Yeah, sure, the developer “explains” this in the description, but it is still deceptive IMO. I would not purchase it just for this reason no matter how accurate it was. Do better. ### 5/5 — BJ *2023-01-16, version 2.8.1* Always in my pocket ### 5/5 — Solid app - perfectly useful *2023-01-03, version 2.8.1* Needed something to diy a bunch of shelves and this came in handy ### 5/5 — Great app *2022-11-14, version 2.8.1* Tried several other leveling apps, this one is hands down the best yet. ### 5/5 — Very Imptessive *2022-06-23, version 2.8.1* I am using this app on an iPad Pro and the two-axis GUI is not only impressive, but also extremely fast and accurate. Using this app is totally intuitive. ### 5/5 — Wow!!! *2022-05-25, version 2.8.1* I was needing simple and accurate, and luckily found this after trying out a few. Simply try it and you will understand. ### 1/5 — Not good *2022-03-07, version 2.8.1* Inaccurate and turns of phone screen after a second or two. I do not recommend this app ### 1/5 — Doesn’t work *2021-08-25, version 2.8.1* Paid for the ad free version and the calibrate doesn’t actually work. Will be asking for my money back. No updates in over a year. probably not even compatible any more. ## Frequently asked questions about Precise Level ### What does Precise Level do?
