+Frames is an iOS app for planning deep-sky astrophotography and visual observing. It combines a GPU-rendered star atlas with 8,797 deep-sky objects and a deep star layer of roughly 12 million stars, a nightly target ranking that scores every object for your equipment, location and sky, a true field-of-view preview for your camera or eyepiece, session and project tracking, an AR finder that shows where a target sits in your real sky, plate solving that places your own photos on the atlas, and an AI assistant that answers your astrophotography questions, explains any object and adds your gear in plain language.
An iPhone running iOS 18 or newer. No account, no sign-up — your data stays on your device.
+Frames is available on the App Store for iPhone. Download it and start the free trial, and if you have questions or feedback, email support@plus-frames.com or send feedback right from the app.
+Frames Premium is a single subscription that unlocks the whole app: USD 3.99 per month or USD 29.99 per year, each starting with a 7-day free trial. Prices in your region and currency follow Apple's regional pricing and are shown before you confirm. Billing, renewal and cancellation are handled by Apple through your Apple Account — see the Terms of Use for details.
Yes, fair-use limits apply per device and month so the service stays fast and affordable for everyone. Equipment lookups that are answered from the app's built-in equipment catalog — a large, growing dataset covering cameras, telescopes and accessories from many manufacturers — are instant, free and do not count towards any limit. Only requests that need live AI research or chat count. The limits are set as fair use: normal use will not run into them, and they can be adjusted over time.
Yes. Equipment data, explanations and other AI-generated answers can be inaccurate or incomplete. +Frames verifies common equipment against its built-in catalog, but always double-check critical specifications before you rely on them.
Plate solving uses the free service at nova.astrometry.net. You need your own free API key (available after a quick sign-up on their site); the app asks for it the first time you solve an image. Solving time depends on the server queue — usually well under a minute, sometimes a few minutes at busy times.
The atlas, your gear, your projects and the planning tools work offline. Internet is needed for the AI assistant, plate solving and the initial download of object images.
See the Privacy Policy. In short: no account, no tracking, no ads. AI requests are processed through our server without personal identifiers beyond what is technically required.
