LumenLeaf vs Slide Craft

LumenLeaf turns your phone into a real PAR / PPFD grow light meter for monstera, fiddle leaf fig, pothos, snake plant, succulents, orchids, microgreens, herbs, hydroponics, grow tents and legal home cultivation — all free, offline, with no account, no ads, and no subscription. Measure photosynthetically active radiation (PAR / PPFD), Daily Light Integral (DLI), illuminance (lux / foot-candle) and color temperature (Kelvin) directly with your phone's camera and ambient light sensor. WHAT YOU CAN MEASURE - PPFD in µmol/m²/s — real-time photon flux density - DLI in mol/m²/d — daily light integral with photoperiod input - Lux and foot-candle illuminance - Color temperature in Kelvin (CCT) - Per-light-source readings: Sunlight, White LED, HPS, CMH, Fluorescent, Mixed WHY LUMENLEAF - 100% free — every feature, every plant preset, no paywalls - No account, no email, no sign-up - Works fully offline - Available in 20 languages from launch - Honest about accuracy — we tell you when you're on camera mode vs ALS estimate - No physical hardware to buy — interactive printer-paper diffuser walkthrough - Zero data collection, no analytics SDK, no advertising IDs PERFECT FOR - Houseplant parents — monstera, fiddle leaf, pothos, snake plant, calathea, ZZ - Microgreen growers - Indoor herb gardens — basil, mint, rosemary, oregano - Succulents, cacti and orchids - Hydroponic and aeroponic setups - Grow tent hobbyists - Aquarium plant keepers (v1.1) - Legal home cultivation WHAT WE MEASURE THAT OTHER APPS HIDE LumenLeaf is the only free grow light meter that openly distinguishes camera-grade readings from ambient light sensor (ALS) estimates. If your phone does not have a calibration profile, we tell you — no silent fallback that quietly halves your accuracy. HOW IT WORKS LumenLeaf uses your phone's rear camera in RAW mode (when supported) for research-grade illuminance, then converts to PPFD using light-source-specific coefficients. On phones without RAW support, we fall back to the ambient light sensor and clearly mark which mode you are on. A simple printer-paper diffuser is required — build one in under 2 minutes with our visual guide.

Turn good ideas into great pages. SlideCraft is a visual storytelling studio that turns your words into a beautifully laid-out image set. Write an opinion, build a checklist, or recap a weekend — from text to photos, finish a whole set of pages in one style, right on your phone. [PASTE TEXT, AUTO-SPLIT INTO PAGES] Enter a title and body — pages are generated from your paragraphs and length, then fine-tuned page by page. Up to 30 pages per set, so long content unfolds with room to breathe. [20 TEMPLATES, MORE THAN A NEW COLOR] From Minimal Paper and Dark Editorial to Magazine Masthead, Cream Note and Polaroid — every template brings its own layout language, keeping the whole set consistent. [EDIT PAGE BY PAGE, YOUR CALL] Rewrite titles and text, add your own photos, tune font size and byline, insert, delete or move pages. Put what matters where it lands best. [THREE RATIOS FOR DIFFERENT STORIES] 3:4, 1:1 and 4:5 — vertical stories, square cards or feed-friendly notes; pick the frame your content deserves. [PREVIEW THE SET, EXPORT IN HD] Swipe through every page, then export 1080-px-wide PNG images. Save to Photos or share through the system sheet to any app you choose. [DRAFTS ON DEVICE, NO SIGN-IN] Core editing and exporting happen on your device. No account needed; drafts wait right where you left them. Great for knowledge sharing, reading notes, travel recaps, lifestyle lists and product intros. Less layout work. More of what you mean. Good to know: auto-pagination is not AI rewriting — please check text and layout before exporting. SlideCraft does not offer developer cloud sync; system backups depend on your device settings. Keep important material backed up before deleting the app or switching devices.
