Tellback is private practice for the moments you can't redo: the meeting, the interview, the pitch. Read a short article, speak about it for a minute or two, and find out exactly how you came across — before it matters for real. Here's how a rep works: 1. Read a short, curated article (60 seconds). 2. Speak your take out loud (1–2 minutes). 3. Get an honest read on your delivery, dimension by dimension. What you get: • Scores on Coherence, Content Recall, Fluency, Vocabulary, and Confidence • Specific coaching on the fillers, pauses, and habits holding you back • Topics matched to your interests, so practice never feels like homework • Progress charts that prove you're getting steadier over time • Practice in English or Turkish What you say stays yours.

Verdict
The clearest difference is in-app purchases: CABG at none against Tellback's 2. CABG also leads on device support (3 vs 1) and iOS requirement (14.0 vs 17). Tellback's advantage is update cadence (every 9 days vs every 2 months). On price and ads there is nothing between them.
