Verdict
The clearest difference is rating: Smart Logbook at 4.8 against Time's 3.0. Smart Logbook also leads on ads (none vs shown) and ratings volume (153 vs 2). Time's advantage is in-app purchases (none vs 5) and update cadence (monthly vs every 3 months). On price, review sentiment, device support and iOS requirement 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. Smart Logbook sells 5 in-app purchases, starting at $1.99 per month. Time asks for nothing beyond the download.
Smart Logbook holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Smart Logbook has 153 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Time's written reviews are positive against 93% of Smart Logbook's, so the app with the better star average is not the one people write more warmly about.
Time ships an update monthly, Smart Logbook every 3 months. The most recent releases landed on September 24, 2026 and October 8, 2026 respectively.
