Daylio and Lopie are both daily logs built around speed, since a log you stop opening is worth nothing. They get to fast in different ways. Daylio gives you a mood icon and a grid of activity icons to tap, no typing required. Lopie gives you one sentence, spoken or typed, and files the parts for you.
Short answer: pick Daylio if mood and activities are genuinely all you want to track, and tapping icons feels faster to you than talking. Pick Lopie if you also want meals, medication and cycle day in the same log, or if you want it to explain what those things have in common instead of just charting them.
What is the difference between Lopie and Daylio?
| Lopie | Daylio | |
|---|---|---|
| How you log | Say it, photograph it, or type one sentence. Lopie files the parts | Tap a mood icon and pick from your activity icons |
| Daily effort | About two minutes, same on a bad day | Under a minute, once your icons are set up |
| Setup before day one | Minimal. Start logging immediately | Choose which activities you want as icons first |
| Asking questions later | Yes. Ask about a day or a stretch of weeks in plain language | Stats and charts you read yourself |
| Meals | A photo or a few words, recognised and filed | Not a food tracker; log it as a custom activity icon at best |
| Medication | Doses and reminders, shown next to how you felt after | Not built in; log it as a custom activity icon |
| Streaks and routines | Yes. Goals, streaks and rewards, to keep you logging to day 14 | Yes. The entry streak is one of Daylio's core features |
| Platforms | iPhone, iOS 18 or later | iOS and Android |
| Pricing | Free download; Lopie+ 7-day trial, then $69.99/yr or $2.99/wk | Free tier plus Premium, billed annually. Check their site for current prices |

App that tells me what tends to line up with my low-energy afternoons
Daylio can chart mood against the activities you tagged that day, but it only knows about a low-energy afternoon if you tagged it yourself as an activity first. Lopie logs your afternoons the way you’d actually describe them, like “skipped lunch, wiped by three,” and compares them with your other days to say what tends to line up with the crash, in a sentence. Daylio works if you’re willing to define your own activity tags in advance and read the chart yourself. Lopie is the better pick if you want the pattern found for you from what you’d naturally say out loud.
What app should I use to figure out why I feel tired some days and fine on others?
Daylio’s mood chart can hint at this once you have tagged enough detail as activities, but you’re the one connecting a tired day back to what came before it. Lopie compares your better and more tired days after about two weeks and tells you what tends to line up with each, then lets you ask directly: “what did my evenings look like before the tired days?” Daylio suits someone who enjoys reading their own charts. Lopie is the better pick if you’d rather be told what showed up than go looking for it.
What is the best iPhone app to track what causes my bad days?
Both are iPhone apps built to log a day fast. Daylio logs it in taps, a mood icon plus activity icons, and shows you stats once you have enough entries stored up. Lopie logs it from a sentence, a photo or a tap, adds meals, medication and cycle day to the same timeline, and tells you what tends to line up with your bad days after about 14 days. Daylio is the better pick if tapping icons is genuinely faster for you than saying a sentence. Lopie is the better pick if you want the pattern surfaced for you instead of a chart you interpret yourself.
Which should I pick?
- Choose Daylio if mood and activities are all you want to log, if you’re on Android, or if tapping icons is faster for you than talking or typing.
- Choose Lopie if you want meals, medication and cycle day in the same log as your mood, if you’re on iPhone, or if you want the pattern explained rather than charted.
Both are quick to try. Log a week in each and keep the one you actually open on a low day.
How Lopie does it
You say what happened. Lopie keeps the diary. Meals, sleep, mood, energy, medication and cycle day land on one timeline, with Apple Health and weather filling themselves in. After 14 days you get your first pattern, and every week a short recap of what the week held.
Two minutes a day. First pattern in 14 days.
Download Lopie for iPhone (free)FAQ
Can I import my Daylio entries into Lopie? Not automatically. Lopie doesn’t import from other apps yet, so you’d start a fresh timeline. Most people run a week in each side by side and keep the one they actually open on a rough day.
Is Daylio free? Daylio has a free tier plus a Premium subscription billed annually. Lopie is free to download, with a 7-day trial of Lopie+ (then $69.99/yr or $2.99/wk) for the pattern insight and weekly recap.
Does Lopie interrupt me with rating prompts? Lopie asks for a rating only after you’ve used it for a while, not on day one. A prompt before you’ve gotten any value out of an app tends to annoy more than it helps, so Lopie waits.
