Verdict

The call

The clearest difference is rating: Tempdrop at 4.2 against iFertracker's 3.1. Tempdrop also leads on ratings volume (710 vs 55). iFertracker's advantage is in-app purchases (none vs 6) and update cadence (every 2 months vs every 3 months). On price, review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Tempdrop holds the better App Store score, 4.2 against 3.1. That said, the two scores are not equally well evidenced: Tempdrop has 710 ratings behind it against 55, so its average is the more settled of the two. Written reviews complicate that: 40% of iFertracker's written reviews are positive against 38% of Tempdrop's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iFertracker ships an update every 2 months, Tempdrop every 3 months. The most recent releases landed on September 28, 2026 and September 30, 2026 respectively.
