THIS APP REQUIRES A PAID ACCOUNT. Signing up for a new account will start a 30-day free trial.

By combining manual tracking with automatic syncing from other services, we can help you understand and optimise your behaviour. Track whatever you like. Bring your activity from your phone or fitness tracker, add other services like your calendar for greater context on what you're up to, and manually enter anything else you care about. Track everything in one place See numbers about things like your health, activity, productivity, social media, and local weather all together. Data syncs automatically from connected services, so your step count and time asleep are right next to manual data points, like your energy level and how many coffees you drank. But it's not just about raw numbers. We deliver extra context like daily insights on how you're going, track long-term trends and averages, uncover relationships, and send it all in a weekly summary email too. Which habits go together? Correlations are the most powerful part of Exist. By finding relationships in your data, we can help you answer questions like: “What makes me happiest?” “What can I do to be more active?” “When am I most productive?” Track anything you can think of Some things in life can’t be counted by your watch or fitness tracker. With Exist, you can create your own data points to track anything else you want. Use it as a habit tracker, keep a record of medications and symptoms, or track subjective measures like energy and stress levels. Run experiments on your behaviour, and Exist will confirm or rule out your hunches.You can enter data as a quantity, time period, scale from 1–9, percentage, or time of day. Or just add a tag to a day as a quick way to say "this happened".

Verdict
The clearest difference is monetization model: Lifely at freemium against Exist's subscription. Lifely also leads on iOS requirement (15.0 vs 18.0). Exist's advantage is review sentiment (68% vs 33%) and rating (4.1 vs 3.8). On price, update cadence, ads and in-app purchases 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. Exist sells 1 in-app purchase, starting at $8.49 per month and Lifely sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Exist holds the better App Store score, 4.1 against 3.8. That said, the two scores are not equally well evidenced: Exist has 46 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 68% of Exist's written reviews are positive against 33% of Lifely's.
Exist ships an update every 3 weeks, Lifely fortnightly. The most recent releases landed on October 8, 2026 and October 15, 2026 respectively.
