FieldForge
The naturalist’s field notebook for ages 9–14: a specimen is in front of you — sort each note into what you OBSERVE (see, count, measure) and what you THINK (a guess about why or what next). It’s the habit every field scientist learns. On-device; nothing leaves your device.

Meet the cast
FieldForge's cast each embody one part of the naturalist's craft; field-scientist Fenna asks the notebook question — “can you SEE this, or are you guessing why?” — before any note is filed.
Fenna
(Guide) the field naturalist — observe first (what's really there), then interpret (what it might mean), and keep them apart
Loupe
Observation — records only what can be seen, counted, or measured right now
Reasa
Interpretation — forms ideas about why and what happens next, labelled clearly as ideas, never facts
Proxa
The sketch — draws the specimen with measured proportions (the field-notebook craft)
Askel
The question keeper — logs the questions you couldn't answer, and who to ask
What's inside
