## What is Deflection Lite?

Deflection Lite is the most interactive, fast, and precise app available for structural beam analysis.  Simply drag loads and supports on the beam, and see how it bends.

RESULTS

Calculate reactions, shear force, bending moment, and beam deflection quickly and easily.

CROSS SECTION DATABASES

Specify elastic modulus and moment of inertia values directly, or find common shapes and materials using the built-in databases, which include most international steel sections, as well as some aluminum and wood shapes.

UNLIMITED LOADS AND SUPPORTS

Simply drag any load or support on the beam.

• Concentrated point loads
• Distributed loads
• Moment loads
• Simple supports
• Fixed supports
• Fixed hinges
• Floating Gerber hinges

OTHER FEATURES

• Export your design to a permalink that you can share.
• Automatic detection of local maxima and minima in diagrams
• Metric and standard measurement units

### 4/5 — Much improved, but would benefit from better in-application checks/instruction

*2024-07-26*

Perhaps better instruction and/or step-by-step wizards to repeat tasks.  For example, beam self-weight seems to be missing, so you have to remember to adjust a manual distributed load on every beam change.  That said, recent upgrades to this app have been very good, and it does feel a lot more useable these days.

**Developer response:** Our apps are designed for competent structural, mechanical, and civil engineering professionals with years of training and experience using similar tools in the industry.  Deflection Lite contains only a subset of the functionality and complexity that the other tiers offer.  We are reachable by email contact@ketchep.com to answer questions, provide documentation, and help process refunds.

### 2/5 — Needs better instruction and step-by-step wizards

*2024-03-13*

Needs better instruction and step-by-step wizards.  Maybe it works, maybe it doesn’t, who knows — so hard to figure out the unintuitive UI that you never quite know what it’s doing.  Honestly, needs a redesign with some stronger UI folks.

### 4/5 — Inclinaison des forces

*2022-04-06*

Bonjour, serait-il possible d’intégrer un paramètre pour incliner les forces ponctuels et réparties ou simplement intégrer la possibilité d’intégrer une force horizontale ?  

Seul défaut de l.application

### 1/5 — Clumsy UI

*2020-10-13*

Clums y UI coupled with limited functionality has me looking for something better.

**Developer response:** Thank you for your honest feedback.  If you would like to share more details with us by emailing contact@ketchep.com, we would try our best to address them.  We look forward to hear from you!

### 1/5 — Civil engineer

*2020-09-14*

Terrible app, what a pain in the neck to use. Poorly designed application, please refund my purchase.

**Developer response:** We continuously make improvements to the app based on user feedback, and we are sorry it did not meet your expectations.  We would love to hear about your experience, and we can help you further if you email us directly at contact@ketchep.com.  We look forward to hear from you!

### 4/5 — Bom

*2017-10-13*

Só que pra ver os diagramas tem que pagar... deveria ter mais opções, como pórticos ou vigas inclinadas

### 1/5 — Uma porcaria

*2017-06-04*

Apenas o pago. Esse não presta

**Developer response:** Desculpe, você não está satisfeito com o nosso aplicativo. Poderá nos enviar um e-mail para contact@ketchep.com? Queremos ouvir mais sobre sua preocupação, e gostaríamos de corrigi-lo.

### 1/5 — Não funciona

*2016-06-28*

Só monta, não faz cálculo nenhum

### 5/5 — About program

*2015-06-03*

Very good
