How we picked these apps
We focused on apps that use clear caffeine half-life models and give you a realistic cutoff time for your last cup. Just logging milligrams isn’t enough. You need to know when to stop. We tested on iOS and Android to cover the widest audience and gave extra credit to tools that store data locally or ask for minimal permissions. Apps that only tally caffeine without tying intake to a bedtime were left out. We also made room for a jet lag planner because it applies caffeine timing in a sleep-relevant way, even if it isn’t a daily tracker. The result is a tight set of caffeine sleep planner alternatives that actually help you stop guessing.
