Battery Sensei vs AlDente.What's the same, what isn't.
AlDente is the tool a lot of MacBook owners reach for first. It's good, paid software. Battery Sensei is a free, open-source alternative with a calmer default and a built-in battery journal. Here is the side-by-side, written by someone who has used both.

Where Sensei is different
- Free, forever, open source. No tiers, no licence, no upsell. You can read the code on GitHub and you keep using Sensei even if the project pauses.
- Smart low-battery alerts as a first-class feature. Three presets (Zen, Regular, Senpai) or your own thresholds, auto-dismiss times, and a calm hierarchy of nudges, warnings, and full-screen alerts.
- A plain-English battery journal. Cycles, rescues, plateaus, capacity over time, written in sentences instead of vendor jargon. Stays on your Mac.
- Calm aesthetic. Single-purpose menu-bar tool, sumi + washi typography, native AppKit + SwiftUI. No dock icon, no notification noise.
Where AlDente still wins
AlDente Pro has more advanced power features: discharge mode, sailing, heat-aware modes, and a longer history as the best-known charge-limit app on macOS. If you want maximum granular control and you do not mind a one-time licence, AlDente is the deeper tool.
Common questions
- Is Battery Sensei really free, or is there a paid tier later?
- Free for everyone, no tiers, no in-app purchases, no upsell. Sensei is open source on GitHub. AlDente Pro is paid (one-time licence, plus a family option) and closed source.
- Does Battery Sensei do everything AlDente does?
- Most of what most people use AlDente for, yes: charge limit, Travel Mode for trips, native menu-bar status. Sensei adds smart low-battery alerts at thresholds you choose and a plain-English battery history. AlDente Pro has additional power features like discharge mode and sailing/calibration that Sensei does not match.
- When should I pick AlDente instead?
- If you want the most fine-grained battery control on macOS today (heat-mode, sailing, discharge), AlDente Pro is the deeper tool. Sensei prioritises calm defaults and a quiet menu-bar story over an exhaustive feature list.
- Will switching from AlDente to Battery Sensei lose my data?
- No history is lost in macOS itself. Sensei starts a fresh battery journal the day you install it. You can run both apps briefly during a switchover, then uninstall the one you do not want.
- Are charge limits safe? Does Apple support them?
- Apple already implements Optimized Battery Charging in macOS to hold around 80% based on your habits. Manual charge-limit tools like Battery Sensei or AlDente sit on top of that, letting you set the cap explicitly. Apple's own guidance is that lithium-ion ages faster the longer it sits at 100%.
