THIS APP REQUIRES A PAID ACCOUNT. Signing up for a new account will start a 30-day free trial. After your trial, you can choose to purchase a subscription using in-app purchase if you wish to continue using Exist. 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 call

The clearest difference is monetization model: When The Last Time at freemium against Exist's subscription. When The Last Time also leads on rating (4.6 vs 4.1) and update cadence (every 2 days vs every 3 weeks). Exist's advantage is ads (none vs shown) and review sentiment (68% vs 60%). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Exist sells 1 in-app purchase, starting at $8.49 per month and When The Last Time sells 10 in-app purchases, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

When The Last Time holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 46 and 25 respectively. Written reviews complicate that: 68% of Exist's written reviews are positive against 60% of When The Last Time's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Exist ships an update every 3 weeks, When The Last Time every 2 days. The most recent releases landed on June 9, 2026 and September 23, 2026 respectively.
