As answered by people managing JavaScript Operator Lookup and Setapp.
Setapp's answer:
Setapp was created in 2016 by MacPaw, the company behind apps such as CleanMyMac, ClearVPN, and more. The key idea behind Setapp was to give users a simple way to discover high-quality apps for Mac. Over the years, the catalog has grown to over 260 apps and now includes tools for Mac, iOS, and web. Setapp is localized in eight languages and has users all over the world. Here are the key dates:
November 2016: Setapp closed beta is launched for the press, opinion leaders, and influencers. December 6, 2016: Setapp Beta release. January 25, 2017: Setapp public release. August 6, 2020: Setapp let users install iOS apps. August 11, 2021: Setapp arrives on iPhone and iPad. March, 2026: Single app purchase via Setapp Marketplace is introduced. Now, Setapp includes 260+ apps, 50+ iOS apps, and about 10 web apps with more to come.
Setapp's answer:
Setapp's key differentiators:
-Curation. Setapp is a curated platform with trusted, hand-picked apps — not a place filled with self-submitted apps.
-Professional focus. Setapp includes apps aimed at improving productivity and workflows for professionals who rely on their Macs. Setapp users range from developers and marketers to educators, healthcare experts, logistics and retail professionals, and more.
-Flexible access. Users have two ways to get apps: a single-fee subscription to 260+ fully unlocked Mac, iOS, and web apps; or individual app purchases via Setapp Marketplace, for those who need just a few apps rather than the full catalog.
-Security. Setapp holds ISO/IEC 27001:2022, SOC 2, and GDPR certifications. Apps are not permitted to display ads or include hidden in-app purchases.
-AI access. AI+ plans give access to all popular LLM models — GPT, Claude, Gemini, and Grok — through a single gateway.
Setapp gives users apps they can count on. It’s not an endless store but a curated collection of apps worth users’ time and money.
Setapp's answer:
-Quality over volume. The catalog includes only hand-picked, trusted apps. When downloading an app from Setapp, users can be sure it is high quality and safe to use.
-Trusted apps, no fillers. Every app is Apple-notarized, ad-free, fully unlocked, and has no features locked behind additional paywalls. Getting apps through Setapp means avoiding malware and unpleasant surprises.
-Save costs. Setapp Membership offers access to over 260 apps for a flat fee — no need to subscribe to multiple individual apps and juggle subscriptions. In Setapp Marketplace, users can purchase hand-picked, trusted apps individually, with no need to double-check quality or security.
Setapp's answer:
Setapp is actively used by professionals who rely heavily on their Macs and want to improve their workflows — including developers, IT specialists, content creators, designers, marketers, writers, educators, students, and specialists in agriculture, logistics, retail, healthcare, and other fields.
