Verdict
The clearest difference is rating: iDay at 4.7 against Accumulate's 4.0. iDay also leads on ratings volume (71 vs 1). Accumulate's advantage is ads (none vs shown) and update cadence (every 10 days vs every 2 months). On price, in-app purchases, monetization model 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. iDay sells 1 one-off in-app purchase and Accumulate sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
iDay holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: iDay has 71 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 89% of iDay's written reviews are positive against 100% of Accumulate's, so the app with the better star average is not the one people write more warmly about.
iDay ships an update every 2 months, Accumulate every 10 days. The most recent releases landed on October 15, 2026 and September 30, 2026 respectively.
