sSLOPE — Lightweight mobile slope-stability solver for quick on‑site checks

Peter Salakani

05/27/2026

sSLOPE is a compact iPhone app that uses a simplified Bishop method to deliver fast slope stability estimates (FOS) with features like layered soils (up to 7), water table and ponding, surcharge and pseudo‑static seismic loads, soil‑nail and end‑anchored supports, Hoek‑Brown criterion, and PDF reporting — ideal for quick field checks though limited in model complexity and platform availability.

In its current iteration, sSLOPE aims to deliver a concise slope stability assessment on mobile devices. The application emphasizes simplicity and rapid usability. It implements the simplified Bishop method (the method of slices) to discretize the soil/rock mass and compute the Factor of Safety (FOS).

Supports analysis of horizontally layered soil slopes (up to seven layers) in the latest release (sSLOPE v3.0).
The water table can be used to calculate pore pressures and to represent ponded water above the slope surface.
Vertical external loading (a distributed compression) can be applied to the upper portion of the slope model.
Pseudo-static seismic loads can be included by specifying horizontal and/or vertical seismic load coefficients.
End-anchored and soil-nail reinforcement models are available to represent slope stabilization measures.
Failure surface search limits are adjustable to narrow the search area and improve accuracy.
Stability assessment supports both Mohr-Coulomb and Generalized Hoek-Brown strength criteria for soil and rock slopes.
The Settings tab allows configuration of main analysis parameters, including units of measurement and project title.
The Report page presents a brief summary of results and input data; the report function saves the model’s input and output to a PDF, which can be shared via email.

Overview

sSLOPE is a Commercial software in the category Business developed by Roozbeh Geraili Mikola.

The latest version of sSLOPE is 3.0.0, released on 05/26/2026. It was initially added to our database on 05/26/2026.

sSLOPE runs on the following operating systems: iOS.

Users of sSLOPE gave it a rating of 4 out of 5 stars.

Pros

Designed specifically for mobile — quick slope stability analyses on iPhone/iPod touch with a small app size (4.1 MB).
Simple, user-friendly interface aimed at fast model setup and result interpretation (renovated GUI in v2.0).
Uses the simplified Bishop method (method of slices) — suitable for many common circular failure analyses.
Supports horizontally layered soil slopes (up to 7 layers) and both SI and Imperial units.
Handles important real-world effects: water table (including ponded water), surcharge (vertical distributed loading), and pseudo‑static seismic loads (horizontal/vertical coefficients).
Includes slope reinforcement modelling: soil nails and end‑anchored supports.
Offers both Mohr–Coulomb and generalized Hoek–Brown strength criteria (useful for soil and rock slope assessments).
Failure surface search limits can be modified to improve accuracy of the search.
Generates a two‑page PDF report of inputs and outputs which can be emailed directly from the app.
Privacy: developer states the app does not collect user data (per App Store listing).
Low cost compared with many desktop geotechnical packages (listed price $3.99).
Actively maintained: changelog shows feature additions and bug fixes (latest v3.0.0 adds End Anchored reinforcement).

Cons

Methodological limitations: only the simplified Bishop method is implemented — no full Bishop, Janbu, Spencer, or limit equilibrium alternatives for more rigorous or non‑circular failures.
Model geometry limited to horizontally layered slopes — not suitable for arbitrary geometries or complex 2D/3D problems.
Maximum of seven layers may be restrictive for complex stratigraphy.
Mobile interface and screen size limit building and inspecting complex models compared with desktop software.
Search algorithm and numerical options appear limited (few advanced solver/mesh controls exposed to the user).
Report output is brief (two pages) and may lack the detailed plotting, slice diagrams, or export formats (e.g., CSV, DXF) expected by advanced engineers.
iOS only (requires iOS 14.0 or later) — no Android or desktop versions noted.
Very few user reviews (1 rating on the App Store) — limited public feedback to judge reliability and real‑world performance.
No explicit third‑party verification or published validation studies referenced on product pages — users may want to verify results against established tools for critical designs.
Paid app with limited trial/demo information visible — uncertain refund/trial policy.

FAQ

What is sSLOPE?

sSLOPE is a mobile app for quick slope stability analysis that uses the simplified Bishop method (method of slices) to compute Factor of Safety (FOS) for soil and rock slopes.

Who developed sSLOPE?

sSLOPE was developed by Roozbeh Geraili Mikola.

On which devices and OS does sSLOPE run?

sSLOPE is an iPhone/iPod touch app and requires iOS 14.0 or later.

How much does sSLOPE cost?

sSLOPE is a paid app on the App Store (price shown in the store; historically listed at $3.99). Check the App Store for current pricing.

What types of analyses and features does sSLOPE include?

Key features include: simplified Bishop method analysis, support for horizontally layered slopes (up to 7 layers), water table and ponded water, vertical surcharge loads, pseudo-static seismic loads (horizontal/vertical), support modeling for soil nails and end-anchored reinforcement, modifiable failure-surface search limits, Mohr-Coulomb and generalized Hoek-Brown strength criteria, PDF report generation and email, and both SI and Imperial units.

Can sSLOPE analyze rock slopes as well as soil slopes?

Yes. In addition to Mohr-Coulomb for soils, sSLOPE supports the generalized Hoek-Brown strength criterion to assess stability of rock slopes.

How does sSLOPE handle groundwater and pore pressure?

You can define a water table in the model; sSLOPE uses it to calculate pore pressures and can also represent ponded water above the slope surface.

Does sSLOPE produce reports or allow exporting results?

Yes. The app can generate a brief two-page PDF report containing model inputs and analysis results, which can be saved and sent via email from the app.

What input/model limits should I be aware of?

Current limits include horizontally layered slopes with up to seven layers and configurable failure-surface search limits. Use the Settings tab to configure analysis parameters and units.

What are the app’s privacy and data practices?

The developer states that the app does not collect any data. For details, the App Store listing links to the developer’s privacy policy on the RoozbehGM website.
