Act as an 'Image-to-Prompt Engineer'. Your primary role is to bridge the gap between visual inspiration and text-to-image AI generation by providing highly detailed and optimized English prompts based on user-uploaded images. Purpose and Goals: * Analyze visual data from uploaded images to identify subjects, artistic styles, technical lighting, color palettes, and compositions. * Translate visual elements into structured English prompts that are compatible with top-tier image generation m
★☆☆☆☆ Mantas · Oct 14, 2026
Why doesn't it work with an external USB-C wireless mic? This app seems to have the lowest latency of all I tested. The second best was the "Extra Mic" app. However, there is still a clearly noticeable difference between them latency wise. It would be extremely useful if it would work with external USB-C mics as an external mic is a must for me.
★☆☆☆☆ Julie Johnston · Oct 29, 2026
I'm all for accessibility, but the blistering volume gets extremely painful for those around you. I have to wear earplugs at the office because of this app. Wear hearing protection, and get your hearing checked, so you can use regular volume control.
★☆☆☆☆ bee MacG · Sep 19, 2026
Literally the only thing the app does is piss me off. I only ever tears its ugly head when I'm in the middle of something and can't walk to my phone, and it reduces the volume because it says it was harmful. The most frustrating thing along with randomly treating me like a child at 35 it also has screwed up my Bluetooth ability to properly recognize my devices I no longer have auto connect even to my car. I have the option selected, but it won't work. I have to forget my devices and then re-pair
★☆☆☆☆ Kevin Rye · Oct 25, 2026
This has no impact whatsoever on the earphones when listening to audio on my phone. None of these apps do.
★☆☆☆☆ Sanskriti Santosh · Oct 26, 2026
One of the worst performing apps I have ever came across the app quality was already worse when I first tried it, but it didn't end there it even affected my device my phone and earphone to the earphone is having glitches whatever I'm doing listening to music watching reels YouTube video it's like it gets stuck after 2-3 minutes of Playing and suddenly the sound or voices doesn't match to the voice playing in my earbuds
