TeachBoard combines a drawing board, voice recording and lesson export on Android. Its intended audience is teachers, tutors and coaching classes who want to explain material without assembling a desktop recording setup. The central idea is to write or annotate while speaking, then give students either the resulting video or a static PDF.
This First look uses the official Google Play description. We have not recorded a lesson, tested stylus behavior or checked exported files. The documented workflow is useful to examine, while handwriting quality, audio clarity and classroom suitability still need a practical evaluation on your own device.
Based on official store information. We have not tested this app hands-on.
What it does
The board supports pens, pencils, markers, highlighters and calligraphy brushes, with colour and thickness controls. Typed text and a set of ready-made shapes can supplement handwriting. White, black and grid backgrounds provide different starting points. The developer also describes stylus support and palm rejection, which should be checked with the actual pen and screen you plan to use.
You can add photographs from the gallery or camera and import PDF pages to annotate. That makes the app relevant to working through a worksheet, marking a diagram or explaining an existing set of notes. Images can be moved, resized and rotated. Use material you have permission to reproduce, especially if the lesson will be shared outside a small teaching group.
Recording captures the board and voice as an MP4 video. Pausing and continuing leaves paused portions out according to the description, and recording and sound quality can be selected. A concrete lesson workflow would be to prepare the pages, check microphone pickup, record one explanation and inspect the saved output before distributing a full lesson.
Boards can contain multiple pages and live in folders organised by class, subject or group. A separate feature records students' questions for later explanation. A recycle bin is listed for recovering accidental deletions. These are organisational aids; we have not checked recovery limits or what happens when a device is lost.
Videos can be saved to the gallery and shared through familiar messaging, video and email services. Boards can also be exported as PDFs. Keep the distinction clear: the PDF preserves a static explanation, while the video includes the timing and voice that show how you arrived at the result.
Before you install
A phone can make recording accessible, but its screen is not automatically large enough for every subject. Check whether fractions, labels and diagrams remain legible at the size students will view. A large board full of small writing can become difficult to follow after video compression or on another phone.
The developer says work stays on the device, with no account required and offline operation. A PIN or fingerprint app lock is listed. Those claims concern the app's local workflow; sharing a video through another service introduces that service's access and storage conditions. We have not audited either the local protection or external sharing path.
Audio deserves its own check. A clear diagram paired with quiet speech or distracting room noise may not be useful. Record a short representative segment using the actual microphone position and review it with headphones. The app's quality settings do not establish the quality of the room or microphone.
A supported Chromebook or larger screen may offer a different experience from a small phone. The description mentions keyboard shortcuts on Chromebooks and laptops, but compatibility should be confirmed for the device you intend to use. Do not assume every stylus or shortcut behaves identically across devices.
Price and access
The free plan starts with a seven-day trial allowing recordings of any length, then limits free recordings to two minutes while keeping unlimited boards. Free videos and PDFs carry a TeachBoard watermark. Lifetime is a one-time purchase for longer recordings and adding your own name or logo; Pro Lifetime additionally removes the TeachBoard watermark. The source does not supply regional amounts, so check checkout terms. There is no subscription. The developer says purchases restore with the same Google account.
Our take
The attractive part is keeping preparation, explanation and export close together. A tutor could annotate a student's question, explain the reasoning aloud and share a compact lesson without moving the board between several applications. The separate PDF option also lets a learner revisit a final diagram without searching through the recording.
Start with one real lesson segment, not a collection of decorative boards. Check that a student can read the result, hear the reasoning and identify the step they need. Then decide whether the free recording limit and watermark meet your needs or a paid tier is justified.
We have not assessed recording stability, export fidelity, palm rejection or recovery behavior. Our take is about a coherent documented teaching workflow, with the plan distinctions and device-specific writing experience central to the decision.
Prepare the sequence before recording a complicated derivation. A blank board offers freedom, but a few clearly separated pages can help the learner understand where one idea ends and another begins. Do not assume that recording continuously is the best explanation.
