Verdict
The clearest difference is ads: BigPlan at none against CalendarLife's shown. BigPlan also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 80%). CalendarLife's advantage is ratings volume (545 vs 4). On price, update cadence, in-app purchases and monetization model 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. CalendarLife sells 13 in-app purchases, starting at $1.99 per year and BigPlan sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
BigPlan holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: CalendarLife has 545 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 80% of CalendarLife's written reviews are positive against 100% of BigPlan's.
CalendarLife ships an update every 6 weeks, BigPlan monthly. The most recent releases landed on September 22, 2026 and June 11, 2026 respectively.
