Question: To my knowledge, [range voting](http://rangevoting.org/) is the most optimal way to run a single-winner election or poll. Aside from being dead simple (e.g. score each choice 0-9, highest sum wins) it's [staggeringly unmatched](http://rangevoting.org/BayRegDum.html) in computer simulations calculating Bayesian regret compared to all other systems regardless of voter utility, strategy, honesty, ignorance, or noise.

Is there a web app for conducting polls with good support for range/score voting? A self-hosted solution is perfectly fine, although unnecessary. Any required architecture or platform will do.

Google has lead me to SurveyMonkey, PollDaddy, EasyPolls, StrawPoll, and none had this. Some came close but the votes weren't kept secret. StrawPoll allows [approval voting](http://rangevoting.org/Approval.html), which is at least a step in the right direction but the results should be hidden until finished.

[BetterPolls](http://betterpolls.com/) has the best implementation I've found but seems relatively small and lacks features such as optional single-IP tallying. (Although it does have a mild captcha.) OAuth login support (e.g. Google+, Facebook) would be ideal. I know it's impossible to stop all ballot stuffing but it would be great to see an app for this superior system, particularly for fast and easy straw polls.

Answer: 
My recommendation is for
<https://github.com/amikula/rangevote>
by Alf Mikula. I know him personally, and have used the software extensively.

PROS
----

It's *very* functional and fairly polished. It has been possibly the most recommended web app among the range voting community. When it was a hosted solution years ago, it was clearly the best software for range voting available.

CONS
----

The author moved on to other projects, and while this project got fairly polished (not beta quality), it hasn't been worked on in many years, so it's using a very old version of Ruby on Rails and may have other age-related weaknesses.

If someone were to fork the project and update it to modern standards, that would be the best solution available.
I'm extremely pleased to have found <https://star.vote/> and also the excellent <https://www.starvoting.us/>. STAR voting is all of the benefits of range (score) voting, with the addition of the feature that, in rare scenarios, made ranked choice perform better. Giving STAR superiority across-the-board, and quite possibly a single system everyone can eventually agree on.
