# Sum AI vs Infinity Transcribe Recorder

The clearest difference is rating: Infinity Transcribe Recorder at 5.0 against Sum AI's 4.5. Infinity Transcribe Recorder also leads on monetization model (ad-supported vs free with in-app purchases). Sum AI's advantage is ratings volume (1.7K vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sum AI sells 9 in-app purchases, starting at $4.99 per 7 days and Infinity Transcribe Recorder sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Infinity Transcribe Recorder holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sum AI has 1.7K ratings behind it against 4, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 12, 2026 and October 30, 2026 respectively.
