Scribble vs Canopydew

Scribble is the fastest way to get a thought out of your head. Most to-do apps make you wait — open the app, find the right list, tap a plus, then type. By then the thought's gone and you're back to scribbling on paper. Scribble opens straight to a blank line with the keyboard already up. Type it, hit return, and it's saved. That's the whole app. • Instant capture — the keyboard is up the moment you open it. No menus, no lists to scroll past. • Rapid-fire — hit return to save and keep going. Empty your head in one sitting. • Natural dates — type "call mom friday" or "renew passport in 2 weeks" and Scribble quietly files the date for you. • Hands-free — say "Hey Siri, Scribble" on your iPhone or Apple Watch and just speak. It lands in your list. • Calm by design — pen-blue ink on warm paper. Nothing to configure, nothing to nag you. No account. No sign-up. No ads. Your jots stay on your device. Scribble isn't trying to be your project manager. It's the napkin that's always in your pocket — just faster.

Canopydew is a commissioning bench for greenhouse climate: it documents measured climate changes around recorded interventions, with baseline and response windows that a grower can review. Temporal association does not establish that an intervention caused a change. Synchronized air-temperature traces from several sensor positions share one scrubbable chart, interventions are marked on the timeline, and the psychrometric arithmetic underneath (saturation vapor pressure, dew point, leaf VPD, daily light integral) follows the FAO equation basis, with methodology links readable inside the app. A session opens on a bundled synthetic example, the Ridge vent response check: 72 observations from three mapped sensors in a propagation house, with one ridge-vent intervention. Scrub the trace to compare positions, then set baseline, response, and recovery windows in the Evidence workspace; Canopydew computes measured temperature and humidity deltas, pairwise sensor disagreement over overlapping time buckets, and time-to-tolerance for the step response. Capture observations by hand, or import a logger CSV with column mapping, units, and timezone; every import is receipted with its SHA-256 digest and a per-row list of anything rejected. Findings accumulate in a revision trail, and the record exports as a packet of PDF, CSV, and JSON. Canopydew suits growers commissioning a new house, consultants verifying vent and screen behavior, and students learning greenhouse physics. Results are informational documentation, not a safety or control system. Every record lives in the app's private on-device container and leaves only through the share sheet or picker you choose; there is nothing to sign into, no advertising, and no analytics, and the app works without any connection at all.
