Running out of iCloud space? Let Slimm slim it down!

Enjoy seamless iCloud syncing and accurate photo memory recommendations, while avoiding hefty storage costs. It's the ultimate, clever solution to your storage woes.
NetBar

Check slow Wi-Fi with download and upload tests, ping checks and the network traffic observed by your iPhone. TEST MORE THAN DOWNLOAD SPEED Watch the speedometer respond to measured throughput. Each download and upload phase targets at least 10 seconds. Check idle and loaded latency, jitter, TCP connection-probe loss, and consistency to understand how your connection behaves during a test. Measurements depend on your network and the test server. CHECK PING BEFORE YOU PLAY Test public endpoints associated with popular games, streaming services, and websites. See reachability, latency, jitter, and consistency together. These are TCP connection checks, not private game-server ping, ICMP packet-loss tests, or playback-quality measurements. SEE LIVE TRAFFIC AND OBSERVED DATA USAGE View download and upload activity in bits or bytes per second. Review Wi-Fi and cellular traffic observed by NetBar, with daily and monthly charts. Observed usage is not a complete carrier bill, router total, or per-app report. KEEP A USEFUL HISTORY Review recent results locally on your iPhone. NetBar Pro adds retained history, comparisons, custom public targets, and CSV export for a closer look at your connection over time. LATEST READINGS AT A GLANCE Start a Live Activity to see the latest measured rates on the Lock Screen and Dynamic Island on supported iPhones. iOS can suspend background apps: readings are marked stale when NetBar cannot take new measurements. This is not continuous monitoring while the app is closed. START FREE. UPGRADE ONCE. Get 3 successful speed tests per day, 7 days of history, built-in service checks, and live traffic readings. Optional NetBar Pro is a one-time purchase for unlimited successful tests, retained history, comparisons, custom public targets, CSV export, and ad removal. No subscription is required. NO ACCOUNT OR VPN REQUIRED Results stay on your device. NetBar does not inspect packet contents, browsing history, or individual app activity. Tests contact public providers and transfer real data, potentially substantial amounts on fast connections. The free version displays Google AdMob banners in History; privacy choices are provided where required. See the privacy policy for provider and advertising data handling. NetBar is not affiliated with or endorsed by the services whose public endpoints it checks. The interface supports English, Hindi, Spanish, French, and German.

Verdict
The clearest difference is ads: Slimm at none against NetBar's shown. On price, update cadence, in-app purchases and device support there is nothing between them.
