| CPU monitoring | Per-core usage, top processes, Apple Silicon aware | Per-core usage, history graphs, frequency, uptime |
| RAM monitoring | Used/available, top memory consumers | Used/wired/compressed/free breakdown, history, pressure gauge |
| Disk activity | Read/write speeds, capacity per volume | Read/write speeds, S.M.A.R.T. status, capacity |
| Network monitoring | Upload/download speed, per-interface | Upload/download speed, per-interface, IP address, public IP |
| Battery info | Charge %, time remaining, cycle count, health | Charge %, time remaining, cycle count, health, condition, temperature |
| GPU temperature | Not available | GPU temp, fan speed, all sensor readings |
| Fan control | Not available | Custom fan rules, per-sensor triggers |
| Weather | Not available | Menu bar weather with forecasts |
| Notifications | Battery alerts only | CPU, RAM, disk, network, temperature, and battery alerts |
| Menu bar customization | Shared single icon with 6 other tools | Individual icons per metric, fully customizable |
| Price | Core free / $20 for 6mo (all 7 tools) | $11.99 one-time |
| Other tools included | Eye rest timer, AI tracker, window manager, keep alive, port kill, cloud costs | None — dedicated system monitor |
| Privacy | 100% local, no telemetry | Local (telemetry opt-in) |
| Update model | Included with active license | Major versions paid, minor updates free |
| Open source | No | No |
The Verdict
iStat Menus is the better choice if detailed system monitoring is your priority — it has deeper sensor access, GPU temperature readouts, fan control, weather, and per-metric menu bar customization that FavTray cannot match. FavTray is the better choice if you want basic system monitoring alongside an eye rest timer, AI cost tracker, window manager, keep-alive tool, port manager, and cloud cost viewer. FavTray consolidates 7 tools into one icon for $3.33/month, while iStat Menus costs $11.99 one-time for system monitoring alone.
Frequently Asked Questions
Is FavTray better than iStat Menus for system monitoring?
No. iStat Menus is a superior dedicated system monitor with deeper sensor data, GPU temperature readings, fan control, weather, and per-metric menu bar icons. FavTray covers the essentials — CPU, RAM, disk, network, and battery — which is sufficient for most developers who want a quick status check. FavTray's advantage is that system monitoring comes bundled with 6 other developer tools in a single menu bar icon.
Can FavTray replace iStat Menus?
For basic monitoring, yes. FavTray shows CPU usage, memory pressure, disk capacity, network speeds, and battery health — the metrics most developers check regularly. If you need GPU temperature monitoring, fan control rules, detailed sensor readouts, or per-metric menu bar graphs, iStat Menus remains the better choice.
Is iStat Menus worth $11.99?
Yes, if system monitoring is important to your workflow. iStat Menus is the most comprehensive macOS system monitor available, with extensive customization and sensor-level detail. For developers who only need occasional system checks alongside other tools, FavTray's included system info may be sufficient at a lower effective cost per tool.
Does FavTray show CPU temperature like iStat Menus?
No. FavTray focuses on CPU utilization, memory usage, disk space, network throughput, and battery metrics. It does not read temperature sensors or provide fan control. For thermal monitoring — especially useful during sustained compilation or ML workloads — iStat Menus is the better option.
