Best Classroom Walkthrough Apps for Principals
By Justin Baeder, The Principal Center — Updated April 2026
I've been doing classroom walkthroughs as a principal for over a decade and have logged thousands of observations. I've also talked with hundreds of principals about their walkthrough practice through Principal Center Radio. These are the apps I've actually used and recommend — with honest notes on each.
Disclosure: Repertoire is built by The Principal Center. Other tools listed are independent products we recommend on merit.
Our Top Pick
Repertoire
Classroom walkthroughs & teacher feedback
Repertoire is built specifically for the most high-leverage part of a principal's job: getting into classrooms and giving teachers useful feedback. It solves the real problem — not the observation itself, but the follow-up. Most feedback never gets sent because writing it takes too long. Repertoire fixes that with a reusable snippet library that lets you compose and send a note in under a minute.

Repertoire

Repertoire is the only walkthrough app built by a practitioner specifically to solve the feedback gap. The core insight: the hard part isn't the observation, it's the follow-up. Repertoire's snippet library lets you assemble and send a personalized feedback email in under a minute — from your own email address, not a system notification.
Beyond feedback, it tracks visit frequency across your whole staff so you always know who you haven't seen in a while. The roster builder is fast: paste a name list, photograph a staff roster, or snap a photo of your whole staff in one shot (Portrait challenge).
Who it's for: Principals who want to give more and better feedback without spending more time on it. Works best for building-level leaders who do their own walkthroughs rather than delegating to a team.
TeachBoost
teachboost.com
TeachBoost is a solid district-level observation and evaluation platform. It's designed around teacher evaluation cycles — goal-setting, observations, mid-year check-ins, and summative ratings — rather than the informal walkthrough practice that most principals actually need to improve.
Who it's for: Districts that want to consolidate their evaluation workflow into one platform and need robust reporting across many schools.
iObservation
Learning Sciences International
iObservation is tightly integrated with the Marzano framework and Marzano's research base. If your district uses Marzano for evaluation, iObservation gives observers a structured rubric experience aligned to the framework's domains and elements. It's comprehensive but can feel slow for informal daily walkthrough use.
Who it's for: Marzano-framework districts that need a rubric-based observation tool built specifically for that model.
Frequently Asked Questions
What's the difference between a walkthrough app and an evaluation platform?
Walkthrough apps are designed for informal, frequent visits — the 5-to-10-minute drop-ins that make up most of a principal's classroom presence. Evaluation platforms are built around formal observation cycles with rubrics, ratings, and documentation. Most principals need both, but they serve different purposes.
Do I need my district to adopt a tool, or can I use one on my own?
Repertoire is designed for individual principals and works without any district setup. District-wide platforms like TeachBoost and iObservation typically require a district-level contract and IT configuration.
What app works best on an iPhone or iPad?
Repertoire is built mobile-first and works equally well on iPhone and iPad. It's optimized for hallway and classroom use — quick note capture, voice memos, and one-tap feedback sending.
