# 75 Days vs 75 Day Challenge

The clearest difference is review sentiment: 75 Day Challenge at 80% against 75 Days's 0%. 75 Day Challenge also leads on ads (none vs shown). 75 Days's advantage is update cadence (fortnightly vs every 2 months) and rating (4.5 vs 4.3). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. 75 Days sells 1 one-off in-app purchase and 75 Day Challenge sells 3 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

75 Days holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 16 and 7 respectively. Written reviews complicate that: 0% of 75 Days's written reviews are positive against 80% of 75 Day Challenge's, so the app with the better star average is not the one people write more warmly about.

75 Days ships an update fortnightly, 75 Day Challenge every 2 months. The most recent releases landed on October 13, 2026 and October 8, 2026 respectively.
