I loved the Affinity apps, but not on a subscription. I don't do subscriptions or 'freemium' for apps, only for content. On desktop I'll move to Krita / Inkscape / Scribus. On iPad, not sure yet. The key here is watching out for proprietary formats that won't open without the app or subscription; this is something we are going through with Microsoft Publisher offboarding right now to ensure we can archive and read the designs in the future. The same applies to Affinity - if you value past creations, export them to a common future-proof format.
