That’s ridiculous. ### 2/5 — Needs Update *2017-03-05, version 2.0.4* Apps hasn't been updated since 2015. When emailing or printing the PRINT or CANCEL icon are not visible. They are there but not visible. Surprised it hasn't been fixed or even commented on. ### 1/5 — App crashes *2015-10-01, version 2.0.2* Does not work with IOS 9 or later. Please fix. ### 1/5 — App crashed *2015-09-30, version 2.0.2* Unable to open app, continues to crash ### 3/5 — Good but... *2015-02-06, version 2.0.1* The is very simple and do well what it is designed for. However, the app close when it push the span options button. Do the same on iPod touch 4th under ios 8.1.3 and also on iPad 3rd under the same ios. ### 2/5 — Could be better *2012-06-18, version 1.2* I appreciate the idea. However, it doesn't lend itself to anything but "2x" construction and even then there is no option to sister members together. I would like to enter custom beam sizes and be able to sister commercial lumber. ### 1/5 — Refund? *2012-03-05, version 1.1.1* Not as useful as I had hoped. I was expecting to be able to find span lengths for custom beam sizes. Guess I just wasted $20. If this is possible I apologize, please let me know. ## Most critical reviews (10 lowest-rated) ### 1/5 — Fails to run *2024-07-20, version 2.15.1* Fails to run on iOS 15.8.2 (iPhone 6s+) stopping on "Generating views…". ### 1/5 — Stopped working *2024-04-19, version 2.15.0* New update messed up app ### 1/5 — Unusable since last upgrade *2024-04-18, version 2.15.0* I have not been able to use the app this week.

Add larger woods and/or multiple smaller woods to make up beams. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
