"body": "Watching SMAART evolve over the years, I know this app will only get better. Would love to see an easier calibration for external microphones, as well as the ability to monitor real time data from a connected computer running SMAART. Overall very useful and beautiful design. I’m sure as it grows it will only become more useful. Thanks Rational",

"rating": 1,
"title": "Subscription only",
"body": "A forced subscription screen right at launch is an instant one-star for me. Users should be able to freely explore an app's interface, customize settings, and get a feel for its functionality before being prompted for credit card details. This current method is a major deterrent and should be reconsidered for a more user-friendly experience. *EDIT* give credit where it’s due: the developers at Rational Acoustics reached out to me directly with a thoughtful and detailed explanation of the constraints they face due to Apple’s current rules around trials and purchases. They were transparent about the tradeoffs involved and acknowledged the value of what I was asking for. I suggested they consider implementing a manual, time-limited trial period (e.g., 7 days of full functionality), something I’ve seen work well in other apps, and they were open to the idea. While I still hope to see a more user-friendly trial experience in a future update, I really appreciate the direct and respectful communication from the team. Here’s hoping that as development continues, they’ll find a solution that allows curious users to explore the app before committing to a subscription. Until then, I’ll keep an eye on updates",

"title": "No free/limited option, forced subscription",
"body": "Nothing in the app listing said anything about EVERY feature being locked behind a subscription. Only after downloading the app, and expecting a limited feature set, I am greeted with a forced subscription page as soon as it opens. Sure, there’s a 7 day trial, but even the cheapest plan option is $60 to purchase outright. This is yet another, greedy, “own nothing and be happy” company that wants to push everyone to subscribe and makes a buyout option insanely overpriced.",

"title": "Needs Remote Access Ability",
"body": "This is a fantastic concept, but it needs the ability to pull real-time data from a computer running Smaart on the same network. Your desktop computer can be running Smaart while your phone pulls all the real-time data so you can be mobile while seeing exactly what’s happening on Smaart on your desktop. Otherwise great app!",
