Intuitive. Effective. Engender a quiet working atmosphere and support your students while they concentrate on their work and complete their assignments effectively! Noise warning light: The noise warning light provides optical and acoustic feedback on the volume level in the classroom + Adapt the sensitivity to different study groups + Ask your students: the duration of downtime needed for evaluation can be varied. + Often a reminder is enough: Set warnings that remind them (as often as necessary) of breaches of the noise limits before a negative evaluation takes place + Save the settings for different situations or study groups! That way, you can switch, for example, between group and individual work phases. Visual Timer: The visual timer gives your pupils the possibility of grasping the remaining time for a work phase with just a glance + Train a sense of time into your students + Set the "direction" of the timer + The duration can be presented as relative or absolute (on a 60-minute scale) + Set whether an acoustic alarm is to sound at the end of the work phase

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
SchoolTool costs $7.99 and GoodGeometry $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
GoodGeometry holds the better App Store score, 1.2 against 1.0. That said, the two scores are not equally well evidenced: GoodGeometry has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of SchoolTool's written reviews are positive against 64% of GoodGeometry's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 9, 2026 and October 12, 2026 respectively.
