WBCheck is a weight and balance utility for pilots that calculates aircraft performance and generates load sheets on iOS.
The App DNA
What makes this app unique?
The app removes the cognitive and time cost of manual POH calculations during preflight, replacing paper-based workflows with a mobile-first, offline-capable interface.
For General aviation pilots and helicopter operators requiring rapid, POH-verified weight and balance calculations for preflight planning.
What does it look like?
Key features
Visualizes takeoff, landing, and zero-fuel points against published aircraft envelopes in real-time as sliders are adjusted.
Calculates IGE and OGE hover ceilings based on density altitude for specific helicopter models.
Produces a timestamped, signed load sheet for records or operational files with one tap.
How much does it cost?
The freemium model uses a single-aircraft free tier to lower the barrier to entry, with Pro subscription and per-model unlocks serving as the primary revenue drivers.
Velocity
Maintenance developmentnew contentmonetizationUX improvementsShow more...

Key takeaways for WBCheck: Weight & Balance
Where is it heading?
The aviation utility market is consolidating around integrated EFB solutions, putting pressure on standalone tools. WBCheck remains advantaged by its offline-first, POH-verified design, which serves as a reliable, low-friction tool for pilots who do not require a full EFB suite.
- The introduction of a 7-day free trial for the full fleet reduces the friction for new users to evaluate the Pro tier.
- The 9-week update cadence indicates a stable, maintenance-focused development cycle that prioritizes reliability over rapid feature iteration.
The SWOT
- POH-verified profiles function as a professional-grade trust signal
- Offline-first architecture removes dependency on ramp connectivity
- One-tap PDF load sheet generation creates a high-utility workflow
- Localized pricing could capture international aviation segments
- Flight-log integration could deepen post-flight utility
- Expansion of helicopter fleet models to increase Pro conversion

Read the full takeBottom line
WBCheck maintains a strong position by focusing on POH-verified accuracy, but the maintenance-only update cadence leaves it vulnerable to EFB suites that bundle weight and balance tools. Prioritizing custom profile flexibility would unlock higher conversion among aircraft owners.
