This app is a AVR tutorial based on ATMEGA16 C language. It is suitable for hobbyist or engineering students. Learning AVR mcu is difficult. The learning curve is steep. The process including reading datasheet, writing code, building prototypes and troubleshooting. The most possible errors are the setting wrong value of registers. Now, AVR tutorial is the solution. The code wizard allow you to set the timer, UART, ADC, interrupt and peripherals by just a few clicks in setting. The proven C source code is generated automatically. Though the code wizard is based on ATMEGA16 mcu, it is easy to port to other ATMEGA mcu since the source code is highly structured Features • AVR architecture review • AVR asm mnemonics & C language • 21 demo projects including LED, buzzer, key switch, lcm16x2, ADC, etc • Code wizard for UART, timer, interrupt, ADC and external peripherals Features in PRO only • Support I2C eeprom 24C01 (128B) ~ 24C512 (64kB) • Support SPI eeprom 25010 (128B) ~ 25M02 (256kB) • Extra demo projects including led matrix 16x16, I2C eeprom, SPI eeprom • Code wizard for I2C eeprom, SPI eeprom, LCM128x64, etc Atmel® and AVR® are registered trademarks or trademarks of Atmel Corporation or its subsidiaries, in the US and/or other countries.

Verdict
The clearest difference is review sentiment: AVR Tutorial at 75% against Wio Link's 0%. AVR Tutorial also leads on rating (5.0 vs 2.0). Wio Link's advantage is in-app purchases (none vs 10) and update cadence (monthly vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. AVR Tutorial sells 10 one-off in-app purchases. Wio Link asks for nothing beyond the download.
AVR Tutorial holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: Wio Link has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 0% of Wio Link's written reviews are positive against 75% of AVR Tutorial's.
Wio Link ships an update monthly, AVR Tutorial every 3 months. The most recent releases landed on September 13, 2026 and September 24, 2026 respectively.
