Session logging
Remember how it actually felt.
Flower, vape, or edible, with twenty effect tags, five stars, and notes.
Capture each session in seconds: the date, the method, the amount, and how it felt. Rate it one to five stars and add any notes worth keeping.
A library of 300+ strains
Look up any strain, offline.
Lineage, terpenes, effects, and flavors for indica, sativa, and hybrid.
Trying something from the library? Add it to your journal with one tap and the details fill themselves in.
Stash tracking
Know what you have on hand.
Log what you added, mark it finished, see how long it lasted.
Each batch keeps its amount, potency, and terpene readings. Leaflog remembers how long it lasted, so you always know what's active and what's history.
Explorer
Charts built from your own journal.
Top rated, sessions per month, effects by strain. Save the ones you keep.
Pick a source, a dimension, and a chart style, or start from ready-made cards, and save the explorations you want to keep.
Private by design
Nothing leaves your iPhone.
No account, no sign-up, no analytics. Optional Leaflog+ backup is end-to-end encrypted, so only you can read it.
