Very good app, 60h rendering a month for Unlimited.
I purchased the UNLIMITED (tier 2) because I have monthly (2-3 day) projects where I would like to complete the project in one fell swoop. I certainly don't use it daily all month long. But for some reason, my account was tagged as suspicious. "If our algorithm detects suspicious activity or high usage on a particular account, we will set a daily usage limit." (https://odio.ai/appsumo-faq#ltd-terms). This means that by needing it for a couple days a month to finish a project, I am suspect. 31x(daily limit) =NOT UNLIMITED MONTHLY.
BUT... the app performs awesomely. I love the options, they are always bringing on new voices and natural voices. The app saves your previous files in case you want to refer to them, and you can organize them by project, so you can work on several projects at the same time. I have used it for several months and it has never glitched or froze--except for when I hit a daily limit.
Daily limit is about 2 hours of voice rendering.
I wish that, being a Tier 2 member, I would be given special permission for the unlimited usage, per the terms. But buyer beware. You must regulate your renderings, and time your project around these limits.
I was using Utrrr (Blakify) and the company went under because it couldn't keep up with the demand (or maybe with the promises). So it would have been better for them to list daily 2 hour limit and monthly 60h rendering (which is a lot!) instead of calling it unlimited. I would prefer them to limit by the week rather than day, because I prefer to do my projects over the course of a couple days. But I suspect they'll fix this.
It would also be good to have a countdown for the daily limit so I can maximize on my purchase benefits without hogging the system.
