Verdict
The clearest difference is rating: TadpoleAI at 5.0 against One's 2.3. One's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (188 vs 1). On price, ads, in-app purchases 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. One sells 15 one-off in-app purchases and TadpoleAI sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
TadpoleAI holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: One has 188 ratings behind it against 1, so its average is the more settled of the two.
