What this app is. What it isn’t. What you could build.

One-liner

A simple tool to calculate frequency from wavelength or period, designed for students and engineers who need quick unit conversions.

Strengths

Ranked #20 for 'frequency' — strong keyword visibility in a niche utility space
Minimalist interface with clear input/output fields, suggesting focus on core functionality
No ads or in-app purchases listed — implies clean user experience potential
Targeted at technical users (e.g., physics, engineering) seeking fast calculations

Weaknesses

0.00 rating from 0 reviews — no user validation; likely untested or unreleased
No visible features beyond basic calculation — may lack advanced options like unit selection or waveform support
No mention of offline use, which is critical for educational tools
No social proof or trust signals (e.g., privacy policy, developer info)

Opportunities

Launch with real user testing and collect early reviews to build credibility
Add unit conversion (Hz, kHz, MHz, RPM) and common wave types (sound, light, radio)
Integrate with science education workflows (e.g., export results to notes or PDF)
Offer a free tier with basic functions and premium for advanced features (e.g., graphing, history)
Target STEM educators by adding classroom-ready templates or quiz modes
