Grafium opens the dashboards and alerts from your self-hosted Grafana® on iPhone. Panels are drawn with native iOS charts, and the app only reads data: it never edits your dashboards, alert rules or server settings. • Time series, stat, gauge, bar chart, table, heatmap, logs, state timeline, geomap and other panels keep the colors, units and thresholds from the dashboard. • Change dashboard variables, pick a time range and turn on auto-refresh. • Open a panel full screen and drag across the chart to read exact values. • See firing and pending alert rules first, with their instances and labels. • Pin the dashboards you check often and search across folders. • Add several servers. Sign in with an API token, username and password, LDAP, JWT, auth proxy or SSO, or connect anonymously. Grafium has no account of its own, no tracking and no ads. Tokens and passwords stay in the iOS Keychain,…
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 5 screenshots above are Grafium's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Grafium runs a light set with one background colour (#FCFCFC) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #44BC64, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
