Choosing the right hotel guest app can significantly impact your guest experience, operational efficiency, and bottom line. Both sigma Software and STAY aim to improve guest interactions and streamline hotel services but do so with different strengths and weaknesses. Your team needs to evaluate which platform aligns better with your hotel’s size, geographic presence, and feature needs.
sigma Software offers foundational guest engagement tools but lacks recent reviews, active support, and a robust feature set. In contrast, STAY provides a comprehensive, well-reviewed solution with a broad feature set, proven global presence, and modern integrations. Are you prepared to prioritize recent user feedback and active support?
sigma Software appears to be an older, less actively supported product with zero recent reviews or verified users. Its rating is nonexistent, and it has no documented features beyond basic guest engagement. Meanwhile, STAY boasts over 200 recent reviews, a 3/5 overall rating, and a 96% likelihood to recommend—highlighting its active user base and ongoing development.
The key difference is the level of trust and credibility built through recent feedback. sigma Software’s lack of updates and reviews over the last six months makes it a risky choice, whereas STAY’s ongoing support and positive sentiment suggest a more reliable vendor.
Would you prefer to invest in a solution with proven ongoing support and recent user validation? Or are you willing to risk an unsupported product with no recent user feedback?
If your hotel needs a straightforward guest app to provide essential hotel information and basic communication, sigma Software might seem like a candidate. However, its limited feature set, lack of recent reviews, and no verified integrations make it difficult to justify. Conversely, STAY’s extensive 14 features—including chatbots, messaging, room service ordering, and multi-lingual support—are designed for hotels seeking a comprehensive guest experience platform.
For large, international, or tech-forward hotels, STAY's integration with 20 partners and its experience working with chains like NH Hotels and RIU make it the clear choice. If your hotel prioritizes digital guest services and operational efficiency, STAY’s proven track record is unmatched.
So, if you want a feature-rich, well-supported solution, STAY wins. But if you prefer a minimal, unsupported platform, sigma might be considered—though it's a gamble.
sigma Software provides no recent reviews, so its usability rating is unknown. Its lack of current user feedback suggests it may not be actively refined or user-friendly today. Meanwhile, STAY scores a 4.78/5 for ease of use, with over 200 recent reviews praising its intuitive interface, simple content management, and smooth onboarding.
STAY’s platform is designed for hotel staff and guests alike, with many reviews highlighting their satisfaction with the easy-to-navigate CMS and mobile app. Given the limited data on sigma, STAY’s high usability score clearly makes it the easier platform to implement and adopt.
Edge: STAY Guest App
sigma Software offers no documented features beyond basic guest communication, making its feature set minimal or undefined. In contrast, STAY boasts 14 features, including a chatbot, automated replies, message routing, room service ordering, local recommendations, hotel directory, multilingual translations, mobile checkout, and guest profiles.
This extensive feature set allows STAY to digitize a wide range of guest services, reducing operational friction and elevating guest satisfaction. If you need a feature-rich platform, STAY provides more options and flexibility.
Edge: STAY Guest App
sigma Software’s support reputation is unknown, with no recent reviews or support ratings available. Conversely, STAY’s customer support scores a 4.83/5, with reviews praising the team’s responsiveness and helpfulness. Feedback mentions that STAY’s support is efficient, though some users note the absence of phone support and regional support hours.
The consistent, positive reviews suggest STAY’s support team is dedicated and reliable, making it the safer choice if ongoing assistance is crucial.
Edge: STAY Guest App
sigma Software currently has no verified integrations, limiting its ability to connect with other hotel systems. STAY, however, has 20 verified partners, including hotelkit, apaleo, SiteMinder, Oracle Hospitality, and Mews, facilitating seamless data exchange and operational cohesion.
The broad range of integrations means STAY can easily fit into your existing tech stack, reducing manual work and improving data consistency. For an interconnected solution, STAY is the clear leader.
Edge: STAY Guest App
sigma Software’s lack of recent reviews and ratings makes comparison impossible. STAY, with 206 reviews in the last six months and a 3/5 overall rating, is actively used and rated by hoteliers worldwide.
Most recent reviews highlight how STAY improves operational efficiency, guest satisfaction, and ease of use. Its high review volume and recent feedback confirm it is the preferred choice among hoteliers.
Edge: STAY Guest App
sigma Software does not disclose any pricing information, suggesting it may have a custom or unknown pricing model. In contrast, STAY charges a straightforward $300 monthly base fee, with no implementation or extra per-room charges.
This transparent pricing model makes budget planning easier. If you want predictable costs alongside a proven solution, STAY offers a clear financial proposition.
Not ideal if your hotel seeks advanced features, regional support, or integration with other systems.
Not ideal if your hotel prefers a minimal, unsupported app or has very limited digital sophistication.
sigma Software is an unsupported, minimal platform with no recent reviews or documented features, making it unsuitable for most hotels needing modern guest engagement. Its lack of active support, integrations, and recent validation makes it a risky choice.
STAY, on the other hand, is a well-supported, feature-rich platform with over 200 recent reviews, proven integrations, and a global presence. It reduces guest wait times, increases operational efficiency, and offers a scalable solution for diverse hotel types.
If your hotel values ongoing support, a broad feature set, and recent positive reviews, STAY is the clear choice. Choose sigma only if your needs are minimal, and you accept the risks of unsupported software.

| Criteria Group | Weight | What It Measures |
|---|---|---|
| Customer Ratings & Reviews |
|
How highly do users recommend this product? Ratings Score, Review Volume, Share of Voice, Review Depth, Review Recency, Success Stories ▾ The most heavily weighted factor. Analyzes average satisfaction ratings (likelihood to recommend, ease of use, support, ROI), total review count relative to category peers, review recency (at least 20 reviews in the trailing 6 months), and share of voice across unique hotel clients to detect selection bias. |
| Partner Ecosystem |
|
How highly do tech partners recommend this company? Partner Recommendations, Integration Quantity, Integration Quality ▾ Evaluates partner recommendations as expert votes of confidence, the number of verified integrations, and ecosystem quality — the average HT Scores of integration partners. Products with higher-quality integration ecosystems are more likely to deliver a connected tech stack. |
| Customer Centricity |
|
How customer-centric is this organization? Certified Support, Review Consistency, Profile Completeness ▾ Assesses whether the company has earned HTR Customer Support Certification, maintains consistent review collection over time (an indicator of feedback-driven culture), and keeps product profiles complete with capabilities, screenshots, pricing, and features. |
| Reach, Staying Power & Resources |
|
How extensive is this company's reach and resourcing? Geographic Reach, Staying Power, Company Resources, Trending Score ▾ Measures global presence (countries and regions served), years in business as a stability proxy, team headcount as a resource proxy, and a trending score based on trailing-twelve-month buyer inquiries, reviews, partner recommendations, and press activity. |
Customer ratings and reviews are by far the most important factor in the HT Score algorithm. HTR does not accept payment for higher rankings. All reviews are verified — only hotel industry practitioners with confirmed affiliations can submit ratings. View full HT Score methodology →
