Verdict

The call

The clearest difference is rating: Glow Eve Period Tracker at 4.7 against iFertracker's 3.1. Glow Eve Period Tracker also leads on ratings volume (114K vs 55) and update cadence (fortnightly vs every 2 months). iFertracker's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Glow Eve Period Tracker holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: Glow Eve Period Tracker has 114K 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 33% of Glow Eve Period Tracker'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, Glow Eve Period Tracker fortnightly. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
