# Nestor Studio — product reference This text companion is generated from the same catalogue used by the website. It includes product descriptions and FAQs, not the complete website or legal terms. Read the linked pages for context and each App Store listing for current availability, pricing and compatibility. Website: https://www.nestor.studio/ ## Mactor Product page: https://www.nestor.studio/mactor/ Platforms: macOS App Store: https://apps.apple.com/us/app/mactor-system-monitor/id6768229965?mt=12 Free, native, and built for Apple Silicon. Real-time CPU, memory, disk, network, and battery metrics live in your menu bar — no subscriptions, no telemetry, no clutter. ### Is Mactor free? Yes. Mactor is free to download and use on macOS 13 or later. Mactor Pro adds an optional suite of cleaning and optimization tools on top of the free monitor. ### Does Mactor collect any data? No. Mactor collects, stores and transmits nothing. Every metric is read from local macOS system APIs and never leaves your Mac. There are no analytics SDKs, ad networks or crash reporters in the app. ### Does Mactor work on Apple Silicon? Yes. Mactor is built natively with SwiftUI and AppKit for Apple Silicon, with no third-party frameworks and no background agents. ### How much disk space and memory does Mactor use? The download is 11.9 MB. Mactor runs as a single lightweight menu bar process, and you can disable any metric you do not need or lengthen the refresh interval to reduce its footprint further.

Yes. InfoSaver is free to download and use on iPhone running iOS 14.1 or later. ### Can I track more than one project at a time? Yes. Create a separate list per project — a renovation, a trip, a move — and nest sublists inside it. Every level keeps its own running total, so you can see both the whole budget and each room or category. ### What can the scanner read? The built-in scanner reads standard product barcodes and QR codes, capturing the encoded information straight into your lists.

A smart, personalized plan that reduces your cigarettes day by day, with achievements and health tracking to keep you going. ### How is this different from quitting cold turkey? Smoke Free reduces your intake gradually. A timer widens the interval between cigarettes a little at a time, so your daily count falls step by step instead of dropping to zero overnight. ### Is Smoke Free free to use? Yes. Smoke Free is free to download and use on iPhone running iOS 15.6 or later. ### Does it show how much money I have saved? Yes. The app tracks both daily savings and the total saved across your whole quit plan, alongside the number of cigarettes you have avoided. ### What health recovery does it track? Smoke Free follows an evidence-based recovery timeline covering your heart, lungs and brain — including milestones such as blood pressure and oxygen levels — and updates continuously as your smoke-free time grows.

AI-powered plans you can start following immediately — no overwhelm, no guessing. ### Do I need an OpenAI account to use Study Mood? No. Study Mood generates plans on-device with Apple Intelligence by default, which needs no account and no internet connection. Supplying your own OpenAI API key is optional and unlocks deeper plans for complex topics. ### Where is my OpenAI API key stored? In your device’s system Keychain. It is never transmitted to Nestor Studio’s servers and is only used to authenticate requests you make to OpenAI. You can remove it from the app at any time. ### Does Study Mood work offline? Plan generation with Apple Intelligence runs entirely on-device, so it works without an internet connection. Your plans, notes and saved resources are stored locally with SwiftData. ### Does it sync between my iPhone, iPad and Mac? Yes. iCloud sync is available as a Pro feature and stores your data in your own iCloud account via CloudKit.

Monolist doesn’t. One clean list, sorted the moment you add a task — Overdue, Today, Upcoming, Someday — with reminders, repeats and iCloud sync across iPhone, iPad and Mac. ### Can I add tasks with Siri? Yes. Say “Add a task in Monolist” to capture a task by voice. Siri and Shortcuts can add and complete tasks, and open tasks can be found in Spotlight. On iPhone and iPad, you can also add a New Task control to Control Center or the Lock Screen, or assign it to the Action button on supported devices. ### Which devices can I use? Monolist works on iPhone and iPad with iOS or iPadOS 18 or later, and Mac with macOS 15 or later. Home Screen widgets keep your list nearby; Lock Screen widgets and the New Task control are available on iPhone and iPad. ### Do I need to create an account? No Monolist account is needed. Open the app and add a task. To sync between devices, sign in to the same iCloud account and enable iCloud sync. Your tasks stay on your devices and in your own iCloud account. ### Can I create more than one list in Monolist? No, and that is the point. Monolist keeps a single list and sorts it for you into Overdue, Today, Upcoming and Someday based on each task’s date. There are no projects, tags or folders to set up or maintain. ### Does Monolist sync between my iPhone, iPad and Mac? Yes. Monolist syncs through CloudKit using your own iCloud account, so your tasks appear on every device signed in to that account. Nothing is sent to Nestor Studio. ### How do reminders work? Give a task a due time and switch on a reminder. Monolist schedules a local notification 5 minutes, 15 minutes, 1 hour or 1 day before it is due, or at a custom time before it is due. Complete the task or snooze it for 15 minutes directly from the notification. Notification permission is requested at the moment you turn a reminder on, not on launch. ### What happens when I complete a repeating task? It rolls forward to its next occurrence instead of disappearing, so a daily or weekly habit stays on the list. When you are finished with it for good, Finish Series ends it while keeping the rule, so reopening it restores the habit. ### Is Monolist free? Yes. Monolist is free to download, with no subscription required for the list, reminders, repeats, search, iCloud sync or the widget.

Bring sales, subscriptions and keyword rankings together, with reports processed on your device and your API key kept in its Keychain. ### Can I try it before connecting my account? Yes. Explore sample data inside the app before adding an App Store Connect key. The sample portfolio runs in memory without network requests. After using a real account, restart the app before entering the demo again. ### What is included for free? Free includes keyword tracking for 2 apps, 2 storefronts per app and 10 keywords per storefront. Sales analytics, subscription reports, country analysis and localization audits have no app-imposed app-count limits. An optional Indie plan is planned for version 1.2.0: 5 apps, 5 storefronts per app and 25 keywords per storefront. Availability and subscription prices will be shown in the app. ### What do I need to connect App Store Connect? Your API key with the Sales and Reports role, its key ID and issuer ID, and your vendor number. Some analytics reports need a one-time request setup with Admin access and time for Apple to prepare them. Add the private key separately on each device. ### Where do my reports and API key go? Reports are processed on your device and sync through your private iCloud database. We do not operate a backend that receives them. Your private key stays in the device-only Keychain, outside backups and iCloud Keychain. From version 1.2.0, RevenueCat handles billing data and a random app identifier after a real account is connected, including on Free. It does not receive your API key, sales reports or tracked keywords. Earlier versions do not use RevenueCat. ### Will my keyword positions refresh every day? Automatic checks depend on network access, service rate limits and the time your device allows the app to run. Open the app to give it time to refresh. A completed daily check is not guaranteed. ### Are popularity and difficulty official Apple figures? No. They are relative estimates calculated by ASO Analytics from public signals, not official Apple search-volume figures. Rankings can vary by storefront, query and check time. ### Which devices are supported? Use ASO Analytics on iPhone and iPad with iOS or iPadOS 18 or later. The Mac download requires macOS 15 or later and an Apple M1 chip or later; the App Store lists it as designed for iPad and not verified for macOS. Check compatibility for your device. Stored reports sync through your private iCloud database, but the API key must be added on each device.
