Getting discouraged by my 'accent'—is recording myself the best way to fix tone errors?

I spend hours recording myself and comparing my audio to native speakers, but I feel like my tones are still off. I’m starting to wonder if I’m just hitting a listening plateau where I can’t hear the micro-differences in pitch anymore. Would a platform like Chickytutor.com provide better, more objective feedback on whether my tonal placement is actually correct, or should I keep grinding with high-quality audio recordings until it clicks? I am asking specifically about learning Igbo, not a generic study routine.
