Verdict
The clearest difference is rating: DFT 101 at 5.0 against Thevenin's 4.3. DFT 101 also leads on in-app purchases (none vs 2). Thevenin's advantage is ratings volume (11 vs 2). On price, review sentiment, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Thevenin sells 2 in-app purchases, starting at $4.99 per month. DFT 101 asks for nothing beyond the download.
DFT 101 holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Thevenin has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
