VTimer is a customizable interval timer that repeats vibration or sound alerts at intervals you set. You can adjust the alert interval and alert length separately, making it easy to fit the timer to workouts, stretching, breathing exercises, study sessions, timed problem-solving, and other repeating routines. Choose vibration or sound for repeating alerts. In sound mode, select an audio file or a video file with playable audio from your device and preview it before using it as your alert sound. On the timer screen, you can check the remaining time, current status, and completed cycle count at a glance. Simple start, pause, and reset controls keep the experience focused and easy to use. Focus on one repeating alert with the single timer, or use several with multi-timers. Save multi-timers with different settings and run up to 10 at once. Full-screen mode hides unnecessary elements and shows the timer in large digits. It is available for the single timer and each individual multi-timer. Check your Lock Screen notifications for the remaining time of up to 3 running timers with the nearest upcoming alerts.

Verdict

The call

The clearest difference is in-app purchases: Periodic Timer at none against VTimer's 1. Periodic Timer also leads on ads (none vs shown) and device support (3 vs 1). VTimer's advantage is update cadence (every 4 weeks vs every 2 months) and iOS requirement (16.1 vs 18.0). On price there is nothing between them.
