**Note:** Logger isn’t free, but you can log up to 50 events without paying (which should last quite a while). After that, you’ll have the option to choose between a small monthly fee or a one-time purchase for lifetime access. If you reach the paywall, it probably means Logger has become part of your routine—and hopefully feels well worth the cost at that point. Logger is a daily habit tracker designed to help you visualize habits across different timeframes, making it easy to see how your day, week, month, or year is shaping up. Whether you’re tracking positive habits like “Went for a Run” or “Great Sleep” or negative ones like “Junk Food” or “Alcohol,” consistently logging these activities will provide powerful insights over time. Simply decide if what you did meets your bar, log it, and let Logger paint the picture of how you're doing over time.

Ask once. Four models answer at the same time, and Quartet gives you the one answer they agree on, with the places they split underneath. Type a question. Four seats light up as GPT, Gemini, Claude and Qwen answer in parallel. When they finish, Quartet writes the quorum: the answer they support together, and a short list of where they disagree, so you can see it rather than guess it. Every thread is remembered. Open it later, ask a follow up, and the panel picks up where it left off. Turn MEMORY off on the ACCOUNT screen and nothing is kept between threads. A new account starts with a hundred credits at no charge. A question costs a few. No keys to paste, no setup, one username. Made for people who already paste the same question into several chatbots and compare by hand. SUBSCRIPTION AND CREDITS Quartet Pro is an auto-renewable subscription at $9.99 per month with 600 credits each month, billed to your Apple ID. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings. Credit packs are one-time purchases: 500 credits for $4.99 and 1500 credits for $12.99.
