Phone running slowly, charging slowly or low brightness? See if your device is overheating using Thermals. Thermals displays your device’s thermal state, as well as how many processors are active on your device and its uptime, as reported by iOS. Thermals helps troubleshoot: • Poor performance — iOS reduces processor speed and potentially disables processors temporarily when the device is hot. • Slow charging — battery charging causes a lot of heat and iOS can limit charging speed to reduce the additional heat that might make a device too hot. • Low maximum brightness — if your device screen stays dark despite being on full brightness, it could be limited by iOS due to heat. • Manufacturing defects — if not all processors are active when the device is cool and not in low power mode. Your device's thermal state is monitored regularly in the background and recorded in the app (if Background App Refresh is enabled). Open the app or tap the widget to record a data point manually. Export the raw data to file for corroboration with Screen Time, Xcode's Instruments, or other development tools. Also an independent Apple Watch app shows the thermal status, active processors and uptime, and thermal history of your watch.
TermScape
Read full descriptionHide full description
Termscape is a native iOS client for a self-hosted NodeTerm Server Edition. Point it at a server you run — over Tailscale, a reverse proxy, or your LAN — and pick up your terminal sessions and coding agents right where you left them, from your phone. No relay. No cloud middleman. No Termscape account. The app talks straight to a server you control, and nothing is stored with the developer. WHAT YOU GET • Live terminals — each session is a real, co-attached tmux view. Scroll the history, select text, and use an accessory key bar for the keys a soft keyboard lacks (Esc, arrows, Tab, pipe, Ctrl). • Agents in your pocket — watch Claude Code, Codex, Gemini and other agents work, with live status badges (running / needs you) and a readable transcript view of the conversation. • Grouped by project — collapsible project cards with per-project session and agent counts, updated live over the wire. • Multi-server — add any number of self-hosted servers, each its own profile. Credentials live in the iOS Keychain, scoped per server. • Account usage — see each managed account's rate-limit windows at a glance. • Dictation — talk to your terminal with on-device speech, or your server's own Whisper. You review before anything is sent. • Local notifications — a banner and badge when an agent finishes or needs you. TRY IT WITH NO SETUP Tap "Explore a demo" on the first screen to drive the full app offline, with no server or account — a live-looking session, agent status, and transcript, all local. REQUIRES A SERVER Termscape is a companion for a self-hosted nodeterm Server Edition instance. It is the client only; you run the server. The nodeterm Server Edition is open source. PRIVATE BY DESIGN The app connects only to the server address you configure. There is no developer backend, no analytics, and no tracking.

Verdict
The clearest difference is update cadence: TermScape at every 2 days against Thermals's every 3 months. Thermals's advantage is chart position (#121 vs unranked) and device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
