Your iPhone manages heat quietly. It slows the processor, dims the screen, pauses background work, and never mentions it. Thermal State mentions it. The app reads the thermal state iOS itself uses to make those decisions — Nominal, Fair, Serious, Critical — and puts it on one screen, in one color, with a plain-language explanation of what the system is doing and what you are likely to notice. ON THE SCREEN - The current thermal state, in full color - What that state means and what it affects - Thermal pressure and memory pressure - Uptime - Battery level and charging status - Low Power Mode - Processor, CPU core count, and active cores - Physical RAM - Radio access type - Storage used and total capacity - System version, device model, and locale - The time the current state began - An option to keep the screen awake while the app is open COLOR SCHEMES The four state colors are a default, not a requirement. Swap them for another palette — including one that trades green and yellow for white and cyan, for anyone who doesn't read green as calm. WIDGETS Home Screen: a Medium widget showing the state, its color, battery level, Low Power Mode, and uptime. Lock Screen: inline and circular widgets, so the state is there before you unlock. WHAT IT DOES NOT DO It does not report degrees. iOS does not make a temperature reading available to apps. What it does make available is the four-state assessment the system acts on — which is the reading that actually predicts what your phone will do next. It does not cool your phone down. No app can. It tells you when your phone is cooling itself, and how hard it is working at it. PRIVACY No account. No sign-in. Anonymous analytics only: a device identifier and interaction events, not linked to your identity and never used for tracking. Free. No subscription, no ads, nothing to unlock.

Woke up before your alarm? Skip it, just for today. With most alarm apps, the only way to stop tomorrow's alarm is to switch it off, and then you have to remember to switch it back on. Alarm Plus lets you skip a single day instead. Your alarm stays on and rings again next time. SKIP A DAY • Tap Skip under any repeating alarm to skip just its next ring • Your alarm stays on, so there's nothing to switch back on • Skip any of your next seven rings in advance, such as a holiday or day off • Changed your mind? Tap Undo • Or just ask Siri: "Skip my next alarm in Alarm Plus" SNOOZE YOUR WAY • Choose any snooze length from 1 to 60 minutes, set per alarm • If you don't respond, it rings again automatically, up to 10 more times ONE‑TIME ALARMS FOR A SPECIFIC DATE • Set an alarm for a specific date and time • Optionally have it delete itself after it rings, so your list stays tidy EVERYTHING YOU EXPECT FROM AN ALARM • Rings even when your iPhone is on silent or in a Focus • Repeat on any days, with Every Day, Weekdays and Weekends shortcuts • Labels, and 22 original alarm sounds, from realistic alarm‑clock beeps and bells to gentle wake‑ups • A countdown to your next alarm • Tap to edit, swipe to skip or delete, touch and hold to duplicate No account, no ads, no tracking. Your alarms stay on your iPhone.

Verdict
The clearest difference is in-app purchases: Alarm Plus at none against Thermal State's 4. Thermal State's advantage is iOS requirement (17.0 vs 26.1). On price, ads and device support there is nothing between them.
