- They diverge on capability: ParentSquare covers Multi-channel delivery, Sky Guide covers Light pollution forecasting.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
ParentSquare
- PowerSchool acquired the company in 2024, so a district that deliberately chose an independent communications vendor now depends on the incumbent student records vendor, and future integration favouritism is a reasonable concern.
- Automatic translation is machine translation. It is adequate for routine notices and unreliable for disciplinary, special education or legal language, where a mistranslation has consequences the district owns.
- Adoption is uneven by design. If some teachers post and others do not, families receive an inconsistent picture and start contacting the school by other channels anyway, which defeats the single record argument.
- Engagement dashboards make individual teacher posting frequency visible to leadership, and districts that use that as a performance measure damage the goodwill the tool depends on.
- Switching cost is high in an unusual way. The valuable asset is the conversation history attached to individual pupils and families, and exports of threaded two way messages are far less useful than the live system.
Sky Guide
- It is iOS-only, unlike SkySafari which also covers Android and desktop.
- It has moved from one-time purchase to a subscription model, and long-time users who paid once for earlier versions have criticised the change publicly.
- Pro tier pricing is high relative to Star Walk 2 for broadly similar core stargazing functionality.
- It has no telescope control, unlike SkySafari Plus and Pro, which limits it to naked-eye and camera-based observing.
- Its relationship to other apps under the same distribution platform is not clearly documented, which makes long-term support commitments harder to assess.

Answered from the vendors’ own pages
ParentSquare: Is it FERPA and COPPA aligned?
ParentSquare contracts as a school official under FERPA and takes direction from the district. Pupil accounts, where enabled, run under district consent rather than parental consent for COPPA purposes.
Sky Guide: Is Sky Guide free?
The base app is free to download; Plus and Pro are subscription upgrades for a larger catalogue and forecasting features.
ParentSquare: Does the PowerSchool acquisition change our contract?
Existing terms run to their end date, but renewals now sit with PowerSchool sales, and districts should expect bundling pressure at renewal rather than standalone pricing.
Sky Guide: Did Sky Guide used to be a one-time purchase?
Yes, earlier versions were sold as a one-time purchase before it moved to the current free-plus-subscription model.
ParentSquare: Can it replace our emergency notification system?
It sends voice, text and email at scale, so most districts do replace one. Confirm the voice call throughput commitment in writing before cancelling a dedicated notification contract.
Sky Guide: Does Sky Guide support telescope control?
No. For telescope control, SkySafari Plus or Pro is the better choice.
