Verdict
The clearest difference is rating: PrepSteady at 5.0 against Fertility Window Planner's 4.0. PrepSteady also leads on ratings volume (7 vs 1). On price, review sentiment, ads and in-app purchases 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. Fertility Window Planner sells 3 in-app purchases, starting at $6.99 per month and PrepSteady sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
PrepSteady holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: PrepSteady has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
