Daylio's five-year retention rates aren't a marketing claim — they're proof that the app actually changes behavior long-term. Loop is genuinely excellent for what it is, but 'free and Android-only' is a ceiling, not a feature. The moment you want iOS, cloud sync, or mood context alongside your habits, Loop has nothing to offer.
Combines mood tracking, micro-journaling, and habit streaks in one polished app. Five-year retention rates fro

Buy at AmazonFull review →Daylio isn't just a habit tracker — it's a habit tracker that asks *how you felt* when you did or skipped something. Over weeks, that data reveals patterns: you skip the gym when you're anxious, you journal more when you're happy. Loop tracks whether you did the thing. Daylio tracks whether the thing is actually working for your life.
Loop's 'completely free, no limits' promise is real and rare. No habit cap, no ads, no 'upgrade to unlock' popups. Daylio's free tier is solid but the features that make it genuinely great — advanced stats, unlimited past entries, themes — sit behind a subscription. For budget-conscious users, that's not a minor footnote, it's the whole decision.
Loop is Android-only with no cloud sync, which means if you ever switch phones, get a tablet, or move to iOS, your data and streaks are gone. Daylio syncs across devices and platforms. For a habit tracker — an app whose entire value is long-term continuity — being locked to one device is a serious structural weakness.
Five-year users recommending Daylio isn't a fluke — it means the app's design actually sustains behavior change over time. Most habit trackers get abandoned in weeks. Loop has a loyal following too, but it's smaller and more niche. When you're choosing a habit tracker, the only stat that matters is whether people are still using it years later — and Daylio wins that hands down.
