Odozi (like odyssey, get it?) is a roughly two-minute-a-day journal for your mental wellbeing. This was built because I personally wasn't great at finding the time to journal in the way that I want to journal. Mainly, the app is focused on mood, sleep, gratitude, a daily win, a source of tension, a free journal, and a couple other data points. This entry should be low-friction even on the busiest of days. In the background, Odozi will capture context from your day (your neighborhood, steps, walking distance, sleep, and screen time) so each entry is already half-filled by the time you open the app. Over time, Odozi turns those small daily check-ins into something you can actually look at: * Mood trend charts that show how you've been feeling across weeks and months * A map with color-coded pins so you can see where your best - and worst - days happened * An analytics view so you can spot unseen correlations between any two data points * A Spotify-Wrapped-style Year in Review you can share * A word cloud built from your own journal entries The app is private by design. There are no accounts and no third party tracking. It will remain that way. Your entries live on your device and nowhere else. Location, HealthKit, and Screen Time access are all optional - the journal works without any of them. Furthermore, if you do want syncing across devices, you can enable iCloud sync in the Profile tab. This will sync your journal across your iPhone, Apple Watch, and Mac using Apple's secure CloudKit service.

Verdict
The clearest difference is in-app purchases: Odozi at none against Lens Cycle Tracker's 1. Odozi also leads on ads (none vs shown). Lens Cycle Tracker's advantage is iOS requirement (15.0 vs 17.0). On price, update cadence and device support there is nothing between them.
