Please fix ### 5/5 — Jegbert *2022-08-21, version 1.7.4* Awesome app ### 5/5 — Amazing app *2022-07-27* I recently used the app to build a gazebo roof. It’s just amazing, everything came out perfect. Thankyou ### 4/5 — Redx roof *2022-06-30* Awesome app. Only gave four stars because you can’t compute jack rafters off your rafter lengths. Needs a place where you could input your first jack rafter in order to step down when stack framing. ### 5/5 — Awesome *2022-04-21, version 1.6.1* HANDS DOWN THE MOST IMPORTANT TOOL NOT IN MY BAGS ### 1/5 — Wrong measurements *2021-09-02* Following the measurements for hip and Jack rafters to the 16th came up with the wrong measurements and a lot of wasted material. Luckily this was just training and not out on the job. My instructor also tried following the measurements and came up with a lot of wasted materials. Definitely not worth the money spent. Should offer a refund. ### 2/5 — Seems ok but *2021-08-20* Seems like a cool app with good features but I don’t like a monthly subscription for a calculator app and also seems to but more suited to the imperial system eg cant use degrees to calculate roof members **Developer response:** Hi just so you know, You can use Degrees or a Roof Pitch for the roof angle. And for measurements you can use CM, MM or Feet and Inches, have a look in the settings of the app. Hopefully that clears up any confusion! ### 1/5 — Don’t know what to say I’ll stick to blocklayer *2021-07-27, version 1.5.9* Can only imagine that the roof builder not yet available is more what I need ie width of build, length, pitch then voila. No trial with this product, pay for it with your peril. Utter crap try blocklayer free even tells you how to setup your mitre saw… ### 1/5 — No just no *2021-05-23* Really difficult to use gutted I’ve lost my money **Developer response:** What did you find hard to understand? Did you look through the tutorials we have on our website? ## Most critical reviews (10 lowest-rated) ### 1/5 — No free trial *2026-07-15, version 6.8.9* I canceled on the fifth day and they charged me $69.99 ### 1/5 — No good *2026-04-29, version 6.8.9* The app will not open for me ### 1/5 — Bait and switch *2024-10-05* You’re not able to try the app without signing up. Looks like each function requires a separate purchase too. ### 1/5 — I don’t like it *2024-07-11* I don’t like the fact that it’s hard to move stuff around And I also don’t like that I can’t build full a frame roofs And I also don’t like that I can’t just put my whole build dementions and just get my lumber count I have to build one wall at the time it sucks ### 1/5 — This is a 5 day trial. *2024-06-21* Found out it was a 5-day trial only AFTER installing the app. I am not ready to build this week, so I immediately deleted the app. I may try it once I am ready with the material. ### 1/5 — App is to new to charge *2024-03-01* This app is extremely basic for them to charge before you even try to use it. they also make you sign up an account with your email. you start getting flooded with spam mail. It says that it’s easy to discontinue their services however that is not the case. I highly recommend NOT using this app ### 1/5 — Broken app. Don’t do it. *2024-02-21* Won’t allow me to sign into any of the apps nor the website. Just gets caught in a loop asking to sign in over and over again. Every time it’s says I am signed it, it’s a different account number in the settings. Purchased the bundle subscription to all apps and have no access to any of it. ### 1/5 — Crashes *2023-08-24* After entering data app will crash randomly and all data entered is lost. Not usable definitely will not be paying 60 a year for this. ### 1/5 — App doesn’t show up on your phone. *2023-08-02* Good looking program but not practical for field use. App purchase does not give you access to web base page. ### 1/5 — Just a basic rafter calculator unless you pay *2022-01-23* I wouldn’t have downloaded this app if I had known every feature beyond the basic rafter calculator had to be purchased…..separately!!! I wish developers would stop promoting their apps as free & then requesting money for the features users are truly after. ## Most praised reviews (10 highest-rated) ### 5/5 — Great app *2026-06-15* This app is super user friendly! It is great for quick onsite designs that help customers visualize ideas and expand on them. ### 5/5 — !! *2025-10-01* Не могу оплатить премиум ### 5/5 — Mal *2025-09-28, version 6.7.9* No se puede pagar por mes ### 5/5 — Free version *2025-02-21* The free version only does the common rafter, but it goes in detail, having all measurements no matter where you pull your tape when building it. Very useful for the common rafter. I have no doubt the paid version is better! ### 5/5 — George J gomez *2025-02-14, version 6.1.9* Great app ### 5/5 — ya *2024-10-15, version 6.1.6* great ### 5/5 — A must have *2024-06-26* This series of product is absolutely great and make it easy to calculate everything you need and provides you the list of materials needed. Lea’s guess work and more efficiency. ### 5/5 — Roof cuts *2024-01-12* Love this app ### 5/5 — Green sky roofing *2023-10-16* Best app ever. I’m a carpenter and this is so helpful to make the right cuts and be accurate! ### 5/5 — Ok *2022-09-26* they charge you $24 every month --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
