Pressure-test your next experiment before you run it. Lab+ is a design review tool for wet-lab researchers — built for PhD students, postdocs, and anyone who has to defend an experimental plan to a supervisor. You describe the question, the cell type, the perturbation, and what you plan to measure. Lab+ returns a structured critique: missing controls, statistical pitfalls, infeasible timelines, overlooked literature, and the kinds of things your PI will notice first. WHAT LAB+ DOES • Controls check — flags required and recommended controls you missed, with the rationale • PI-style critique — a skeptical review of your plan, written the way a senior scientist would phrase it • Statistical guidance — recommended test, unit of replication, sample-size guidance for common readouts • Literature check — similar PubMed studies so you can build on or differentiate from published work • Novelty flag — warns when your question has already been answered • Feasibility review — timeline, budget, and equipment sanity checks • PI meeting summary — one-page export for lab meetings and project check-ins • Experiment tracker — log runs, conditions, and results so your next review learns from the last one BUILT FOR • Mammalian cell-culture experiments (v1 scope) • qPCR, Western blot, and cell-viability readouts • Gene knockdown, chemical treatment, and related perturbations HONEST AI DISCLAIMER Lab+ uses AI to generate suggestions. AI can be wrong. Every review must be verified by a human — your supervisor, the primary literature, and your own judgment. Lab+ is a planning aid for trained researchers. It is not a clinical, diagnostic, or medical tool, and it is not a substitute for supervisor review. PRIVACY Your plans and attachments are stored in Supabase (EU region) and tied to your account. We do not sell data, we do not run analytics SDKs, and we do not use your content to train AI models. Delete your account at any time in Profile — it wipes all your data permanently. Made in Belgrade by two researchers who got tired of rerunning experiments that a ten-minute critique would have saved. — Privacy Policy: https://labplus.framer.website/legals/privacy-policy Terms of Use (Apple Standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
